+[![Go Report Card](https://goreportcard.com/badge/Azure/go-autorest)](https://goreportcard.com/report/Azure/go-autorest)
+
+Package go-autorest provides an HTTP request client for use with [Autorest](https://github.com/Azure/autorest.go)-generated API client packages.
+
+An authentication client tested with Azure Active Directory (AAD) is also
+provided in this repo in the package
+`github.com/Azure/go-autorest/autorest/adal`.  Despite its name, this package
+is maintained only as part of the Azure Go SDK and is not related to other
+"ADAL" libraries in [github.com/AzureAD](https://github.com/AzureAD).
+
+## Overview
+
+Package go-autorest implements an HTTP request pipeline suitable for use across
+multiple goroutines and provides the shared routines used by packages generated
+by [Autorest](https://github.com/Azure/autorest.go).
+
+The package breaks sending and responding to HTTP requests into three phases: Preparing, Sending,
+and Responding. A typical pattern is:
+
+```go
+  req, err := Prepare(&http.Request{},
+    token.WithAuthorization())
+
+  resp, err := Send(req,
+    WithLogging(logger),
+    DoErrorIfStatusCode(http.StatusInternalServerError),
+    DoCloseIfError(),
+    DoRetryForAttempts(5, time.Second))
+
+  err = Respond(resp,
+		ByDiscardingBody(),
+    ByClosing())
+```
+
+Each phase relies on decorators to modify and / or manage processing. Decorators may first modify
+and then pass the data along, pass the data first and then modify the result, or wrap themselves
+around passing the data (such as a logger might do). Decorators run in the order provided. For
+example, the following:
+
+```go
+  req, err := Prepare(&http.Request{},
+    WithBaseURL("https://microsoft.com/"),
+    WithPath("a"),
+    WithPath("b"),
+    WithPath("c"))
+```
+
+will set the URL to:
+
+```
+  https://microsoft.com/a/b/c
+```
+
+Preparers and Responders may be shared and re-used (assuming the underlying decorators support
+sharing and re-use). Performant use is obtained by creating one or more Preparers and Responders
+shared among multiple go-routines, and a single Sender shared among multiple sending go-routines,
+all bound together by means of input / output channels.
+
+Decorators hold their passed state within a closure (such as the path components in the example
+above). Be careful to share Preparers and Responders only in a context where such held state
+applies. For example, it may not make sense to share a Preparer that applies a query string from a
+fixed set of values. Similarly, sharing a Responder that reads the response body into a passed
+struct (e.g., `ByUnmarshallingJson`) is likely incorrect.
+
+Errors raised by autorest objects and methods will conform to the `autorest.Error` interface.
+
+See the included examples for more detail. For details on the suggested use of this package by
+generated clients, see the Client described below.
+
+## Helpers
+
+### Handling Swagger Dates
+
+The Swagger specification (https://swagger.io) that drives AutoRest
+(https://github.com/Azure/autorest/) precisely defines two date forms: date and date-time. The
+github.com/Azure/go-autorest/autorest/date package provides time.Time derivations to ensure correct
+parsing and formatting.
+
+### Handling Empty Values
+
+In JSON, missing values have different semantics than empty values. This is especially true for
+services using the HTTP PATCH verb. The JSON submitted with a PATCH request generally contains
+only those values to modify. Missing values are to be left unchanged. Developers, then, require a
+means to both specify an empty value and to leave the value out of the submitted JSON.
+
+The Go JSON package (`encoding/json`) supports the `omitempty` tag. When specified, it omits
+empty values from the rendered JSON. Since Go defines default values for all base types (such as ""
+for string and 0 for int) and provides no means to mark a value as actually empty, the JSON package
+treats default values as meaning empty, omitting them from the rendered JSON. This means that, using
+the Go base types encoded through the default JSON package, it is not possible to create JSON to
+clear a value at the server.
+
+The workaround within the Go community is to use pointers to base types in lieu of base types within
+structures that map to JSON. For example, instead of a value of type `string`, the workaround uses
+`*string`. While this enables distinguishing empty values from those to be unchanged, creating
+pointers to a base type (notably constant, in-line values) requires additional variables. This, for
+example,
+
+```go
+  s := struct {
+    S *string
+  }{ S: &"foo" }
+```
+fails, while, this
+
+```go
+  v := "foo"
+  s := struct {
+    S *string
+  }{ S: &v }
+```
+succeeds.
+
+To ease using pointers, the subpackage `to` contains helpers that convert to and from pointers for
+Go base types which have Swagger analogs. It also provides a helper that converts between
+`map[string]string` and `map[string]*string`, enabling the JSON to specify that the value
+associated with a key should be cleared. With the helpers, the previous example becomes
+
+```go
+  s := struct {
+    S *string
+  }{ S: to.StringPtr("foo") }
+```
+
+## Install
+
+```bash
+go get github.com/Azure/go-autorest/autorest
+go get github.com/Azure/go-autorest/autorest/azure
+go get github.com/Azure/go-autorest/autorest/date
+go get github.com/Azure/go-autorest/autorest/to
+```
+
+### Using with Go Modules
+In [v12.0.1](https://github.com/Azure/go-autorest/pull/386), this repository introduced the following modules.
+
+- autorest/adal
+- autorest/azure/auth
+- autorest/azure/cli
+- autorest/date
+- autorest/mocks
+- autorest/to
+- autorest/validation
+- autorest
+- logger
+- tracing
+
+Tagging cumulative SDK releases as a whole (e.g. `v12.3.0`) is still enabled to support consumers of this repo that have not yet migrated to modules.

+
+   9. Accepting Warranty or Additional Liability. While redistributing

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,

+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,

+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including

+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

-## Migration Guide from v2 -> v3
-
-Version 3 adds several new, frequently requested features.  To do so, it introduces a few breaking changes.  We've worked to keep these as minimal as possible.  This guide explains the breaking changes and how you can quickly update your code.
-
-### `Token.Claims` is now an interface type
-
-The most requested feature from the 2.0 verison of this library was the ability to provide a custom type to the JSON parser for claims. This was implemented by introducing a new interface, `Claims`, to replace `map[string]interface{}`.  We also included two concrete implementations of `Claims`: `MapClaims` and `StandardClaims`.
-
-`MapClaims` is an alias for `map[string]interface{}` with built in validation behavior.  It is the default claims type when using `Parse`.  The usage is unchanged except you must type cast the claims property.
-
-The old example for parsing a token looked like this..
-
-```go
-	if token, err := jwt.Parse(tokenString, keyLookupFunc); err == nil {
-		fmt.Printf("Token for user %v expires %v", token.Claims["user"], token.Claims["exp"])
-	}
-```
-
-is now directly mapped to...
-
-```go
-	if token, err := jwt.Parse(tokenString, keyLookupFunc); err == nil {
-		claims := token.Claims.(jwt.MapClaims)
-		fmt.Printf("Token for user %v expires %v", claims["user"], claims["exp"])
-	}
-```
-
-`StandardClaims` is designed to be embedded in your custom type.  You can supply a custom claims type with the new `ParseWithClaims` function.  Here's an example of using a custom claims type.
-
-```go
-	type MyCustomClaims struct {
-		User string
-		*StandardClaims
-	}
-	
-	if token, err := jwt.ParseWithClaims(tokenString, &MyCustomClaims{}, keyLookupFunc); err == nil {
-		claims := token.Claims.(*MyCustomClaims)
-		fmt.Printf("Token for user %v expires %v", claims.User, claims.StandardClaims.ExpiresAt)
-	}
-```
-
-### `ParseFromRequest` has been moved
-
-To keep this library focused on the tokens without becoming overburdened with complex request processing logic, `ParseFromRequest` and its new companion `ParseFromRequestWithClaims` have been moved to a subpackage, `request`.  The method signatues have also been augmented to receive a new argument: `Extractor`.
-
-`Extractors` do the work of picking the token string out of a request.  The interface is simple and composable.
-
-This simple parsing example:
-
-```go
-	if token, err := jwt.ParseFromRequest(tokenString, req, keyLookupFunc); err == nil {
-		fmt.Printf("Token for user %v expires %v", token.Claims["user"], token.Claims["exp"])
-	}
-```
-
-is directly mapped to:
-
-```go
-	if token, err := request.ParseFromRequest(req, request.OAuth2Extractor, keyLookupFunc); err == nil {
-		claims := token.Claims.(jwt.MapClaims)
-		fmt.Printf("Token for user %v expires %v", claims["user"], claims["exp"])
-	}
-```
-
-There are several concrete `Extractor` types provided for your convenience:
-
-* `HeaderExtractor` will search a list of headers until one contains content.
-* `ArgumentExtractor` will search a list of keys in request query and form arguments until one contains content.
-* `MultiExtractor` will try a list of `Extractors` in order until one returns content.
-* `AuthorizationHeaderExtractor` will look in the `Authorization` header for a `Bearer` token.
-* `OAuth2Extractor` searches the places an OAuth2 token would be specified (per the spec): `Authorization` header and `access_token` argument
-* `PostExtractionFilter` wraps an `Extractor`, allowing you to process the content before it's parsed.  A simple example is stripping the `Bearer ` text from a header
-
-
-### RSA signing methods no longer accept `[]byte` keys
-
-Due to a [critical vulnerability](https://auth0.com/blog/2015/03/31/critical-vulnerabilities-in-json-web-token-libraries/), we've decided the convenience of accepting `[]byte` instead of `rsa.PublicKey` or `rsa.PrivateKey` isn't worth the risk of misuse.
-
-To replace this behavior, we've added two helper methods: `ParseRSAPrivateKeyFromPEM(key []byte) (*rsa.PrivateKey, error)` and `ParseRSAPublicKeyFromPEM(key []byte) (*rsa.PublicKey, error)`.  These are just simple helpers for unpacking PEM encoded PKCS1 and PKCS8 keys. If your keys are encoded any other way, all you need to do is convert them to the `crypto/rsa` package's types.
-
-```go 
-	func keyLookupFunc(*Token) (interface{}, error) {
-		// Don't forget to validate the alg is what you expect:
-		if _, ok := token.Method.(*jwt.SigningMethodRSA); !ok {
-			return nil, fmt.Errorf("Unexpected signing method: %v", token.Header["alg"])
-		}
-		
-		// Look up key 
-		key, err := lookupPublicKey(token.Header["kid"])
-		if err != nil {
-			return nil, err
-		}
-		
-		// Unpack key from PEM encoded PKCS8
-		return jwt.ParseRSAPublicKeyFromPEM(key)
-	}
-```

-
-**BREAKING CHANGES:*** Version 3.0.0 is here. It includes _a lot_ of changes including a few that break the API.  We've tried to break as few things as possible, so there should just be a few type signature changes.  A full list of breaking changes is available in `VERSION_HISTORY.md`.  See `MIGRATION_GUIDE.md` for more information on updating your code.
-
-**NOTICE:** A vulnerability in JWT was [recently published](https://auth0.com/blog/2015/03/31/critical-vulnerabilities-in-json-web-token-libraries/).  As this library doesn't force users to validate the `alg` is what they expected, it's possible your usage is effected.  There will be an update soon to remedy this, and it will likey require backwards-incompatible changes to the API.  In the short term, please make sure your implementation verifies the `alg` is what you expect.
-
-
-## What the heck is a JWT?
-
-JWT.io has [a great introduction](https://jwt.io/introduction) to JSON Web Tokens.
-
-In short, it's a signed JSON object that does something useful (for example, authentication).  It's commonly used for `Bearer` tokens in Oauth 2.  A token is made of three parts, separated by `.`'s.  The first two parts are JSON objects, that have been [base64url](http://tools.ietf.org/html/rfc4648) encoded.  The last part is the signature, encoded the same way.
-
-The first part is called the header.  It contains the necessary information for verifying the last part, the signature.  For example, which encryption method was used for signing and what key was used.
-
-The part in the middle is the interesting bit.  It's called the Claims and contains the actual stuff you care about.  Refer to [the RFC](http://self-issued.info/docs/draft-jones-json-web-token.html) for information about reserved keys and the proper way to add your own.
-
-## What's in the box?
-
-This library supports the parsing and verification as well as the generation and signing of JWTs.  Current supported signing algorithms are HMAC SHA, RSA, RSA-PSS, and ECDSA, though hooks are present for adding your own.
-
-## Examples

-See [the project documentation](https://godoc.org/github.com/dgrijalva/jwt-go) for examples of usage:

-## Extensions
-
-This library publishes all the necessary components for adding your own signing methods.  Simply implement the `SigningMethod` interface and register a factory method using `RegisterSigningMethod`.  
-
-Here's an example of an extension that integrates with the Google App Engine signing tools: https://github.com/someone1/gcp-jwt-go
-
-## Compliance
-
-This library was last reviewed to comply with [RTF 7519](http://www.rfc-editor.org/info/rfc7519) dated May 2015 with a few notable differences: 
-
-* In order to protect against accidental use of [Unsecured JWTs](http://self-issued.info/docs/draft-ietf-oauth-json-web-token.html#UnsecuredJWT), tokens using `alg=none` will only be accepted if the constant `jwt.UnsafeAllowNoneSignatureType` is provided as the key.
-
-## Project Status & Versioning
-
-This library is considered production ready.  Feedback and feature requests are appreciated.  The API should be considered stable.  There should be very few backwards-incompatible changes outside of major version updates (and only with good reason).
-
-This project uses [Semantic Versioning 2.0.0](http://semver.org).  Accepted pull requests will land on `master`.  Periodically, versions will be tagged from `master`.  You can find all the releases on [the project releases page](https://github.com/dgrijalva/jwt-go/releases).
-
-While we try to make it obvious when we make breaking changes, there isn't a great mechanism for pushing announcements out to users.  You may want to use this alternative package include: `gopkg.in/dgrijalva/jwt-go.v2`.  It will do the right thing WRT semantic versioning.
-
-## Usage Tips
-
-### Signing vs Encryption
-
-A token is simply a JSON object that is signed by its author. this tells you exactly two things about the data:
-
-* The author of the token was in the possession of the signing secret
-* The data has not been modified since it was signed
-
-It's important to know that JWT does not provide encryption, which means anyone who has access to the token can read its contents. If you need to protect (encrypt) the data, there is a companion spec, `JWE`, that provides this functionality. JWE is currently outside the scope of this library.
-
-### Choosing a Signing Method
-
-There are several signing methods available, and you should probably take the time to learn about the various options before choosing one.  The principal design decision is most likely going to be symmetric vs asymmetric.
-
-Symmetric signing methods, such as HSA, use only a single secret. This is probably the simplest signing method to use since any `[]byte` can be used as a valid secret. They are also slightly computationally faster to use, though this rarely is enough to matter. Symmetric signing methods work the best when both producers and consumers of tokens are trusted, or even the same system. Since the same secret is used to both sign and validate tokens, you can't easily distribute the key for validation.
-
-Asymmetric signing methods, such as RSA, use different keys for signing and verifying tokens. This makes it possible to produce tokens with a private key, and allow any consumer to access the public key for verification.
-
-### JWT and OAuth
-
-It's worth mentioning that OAuth and JWT are not the same thing. A JWT token is simply a signed JSON object. It can be used anywhere such a thing is useful. There is some confusion, though, as JWT is the most common type of bearer token used in OAuth2 authentication.
-
-Without going too far down the rabbit hole, here's a description of the interaction of these technologies:
-
-* OAuth is a protocol for allowing an identity provider to be separate from the service a user is logging in to.  For example, whenever you use Facebook to log into a different service (Yelp, Spotify, etc), you are using OAuth.
-* OAuth defines several options for passing around authentication data. One popular method is called a "bearer token". A bearer token is simply a string that _should_ only be held by an authenticated user. Thus, simply presenting this token proves your identity. You can probably derive from here why a JWT might make a good bearer token.
-* Because bearer tokens are used for authentication, it's important they're kept secret. This is why transactions that use bearer tokens typically happen over SSL.

+Package uuid provides a pure Go implementation of Universally Unique Identifiers
+(UUID) variant as defined in RFC-4122. This package supports both the creation
+and parsing of UUIDs in different formats.
+
+This package supports the following UUID versions:
+* Version 1, based on timestamp and MAC address (RFC-4122)
+* Version 3, based on MD5 hashing of a named value (RFC-4122)
+* Version 4, based on random numbers (RFC-4122)
+* Version 5, based on SHA-1 hashing of a named value (RFC-4122)
+
+## Project History
+
+This project was originally forked from the
+[github.com/satori/go.uuid](https://github.com/satori/go.uuid) repository after
+it appeared to be no longer maintained, while exhibiting [critical
+flaws](https://github.com/satori/go.uuid/issues/73). We have decided to take
+over this project to ensure it receives regular maintenance for the benefit of
+the larger Go community.
+
+We'd like to thank Maxim Bublis for his hard work on the original iteration of
+the package.
+
+## License
+
+This source code of this package is released under the MIT License. Please see
+the [LICENSE](https://github.com/gofrs/uuid/blob/master/LICENSE) for the full
+content of the license.
+
+## Recommended Package Version
+
+We recommend using v2.0.0+ of this package, as versions prior to 2.0.0 were
+created before our fork of the original package and have some known
+deficiencies.
+
+## Installation
+
+It is recommended to use a package manager like `dep` that understands tagged
+releases of a package, as well as semantic versioning.
+
+If you are unable to make use of a dependency manager with your project, you can
+use the `go get` command to download it directly:
+
+```Shell
+$ go get github.com/gofrs/uuid
+```
+
+## Requirements
+
+Due to subtests not being supported in older versions of Go, this package is
+only regularly tested against Go 1.7+. This package may work perfectly fine with
+Go 1.2+, but support for these older versions is not actively maintained.
+
+## Go 1.11 Modules
+
+As of v3.2.0, this repository no longer adopts Go modules, and v3.2.0 no longer has a `go.mod` file.  As a result, v3.2.0 also drops support for the `github.com/gofrs/uuid/v3` import path. Only module-based consumers are impacted.  With the v3.2.0 release, _all_ gofrs/uuid consumers should use the `github.com/gofrs/uuid` import path.
+
+An existing module-based consumer will continue to be able to build using the `github.com/gofrs/uuid/v3` import path using any valid consumer `go.mod` that worked prior to the publishing of v3.2.0, but any module-based consumer should start using the `github.com/gofrs/uuid` import path when possible and _must_ use the `github.com/gofrs/uuid` import path prior to upgrading to v3.2.0.
+
+Please refer to [Issue #61](https://github.com/gofrs/uuid/issues/61) and [Issue #66](https://github.com/gofrs/uuid/issues/66) for more details.
+
+## Usage
+
+Here is a quick overview of how to use this package. For more detailed
+documentation, please see the [GoDoc Page](http://godoc.org/github.com/gofrs/uuid).
+
+```go
+package main
+
+import (
+	"log"
+
+	"github.com/gofrs/uuid"
+)
+
+// Create a Version 4 UUID, panicking on error.
+// Use this form to initialize package-level variables.
+var u1 = uuid.Must(uuid.NewV4())
+
+func main() {
+	// Create a Version 4 UUID.
+	u2, err := uuid.NewV4()
+	if err != nil {
+		log.Fatalf("failed to generate UUID: %v", err)
+	}
+	log.Printf("generated Version 4 UUID %v", u2)
+
+	// Parse a UUID from a string.
+	s := "6ba7b810-9dad-11d1-80b4-00c04fd430c8"
+	u3, err := uuid.FromString(s)
+	if err != nil {
+		log.Fatalf("failed to parse UUID %q: %v", s, err)
+	}
+	log.Printf("successfully parsed UUID %v", u3)
+}
+```
