+// Package v4 implements signing for AWS V4 signer
+//
+// Provides request signing for request that need to be signed with
+// AWS V4 Signatures.
+//
+// # Standalone Signer
+//
+// Generally using the signer outside of the SDK should not require any additional
+// logic when using Go v1.5 or higher. The signer does this by taking advantage
+// of the URL.EscapedPath method. If your request URI requires additional escaping
+// you many need to use the URL.Opaque to define what the raw URI should be sent
+// to the service as.
+//
+// The signer will first check the URL.Opaque field, and use its value if set.
+// The signer does require the URL.Opaque field to be set in the form of:
+//
+//	"//<hostname>/<path>"
+//
+//	// e.g.
+//	"//example.com/some/path"
+//
+// The leading "//" and hostname are required or the URL.Opaque escaping will
+// not work correctly.
+//
+// If URL.Opaque is not set the signer will fallback to the URL.EscapedPath()
+// method and using the returned value. If you're using Go v1.4 you must set
+// URL.Opaque if the URI path needs escaping. If URL.Opaque is not set with
+// Go v1.5 the signer will fallback to URL.Path.
+//
+// AWS v4 signature validation requires that the canonical string's URI path
+// element must be the URI escaped form of the HTTP request's path.
+// http://docs.aws.amazon.com/general/latest/gr/sigv4-create-canonical-request.html
+//
+// The Go HTTP client will perform escaping automatically on the request. Some
+// of these escaping may cause signature validation errors because the HTTP
+// request differs from the URI path or query that the signature was generated.
+// https://golang.org/pkg/net/url/#URL.EscapedPath
+//
+// Because of this, it is recommended that when using the signer outside of the
+// SDK that explicitly escaping the request prior to being signed is preferable,
+// and will help prevent signature validation errors. This can be done by setting
+// the URL.Opaque or URL.RawPath. The SDK will use URL.Opaque first and then
+// call URL.EscapedPath() if Opaque is not set.
+//
+// If signing a request intended for HTTP2 server, and you're using Go 1.6.2
+// through 1.7.4 you should use the URL.RawPath as the pre-escaped form of the
+// request URL. https://github.com/golang/go/issues/16847 points to a bug in
+// Go pre 1.8 that fails to make HTTP2 requests using absolute URL in the HTTP
+// message. URL.Opaque generally will force Go to make requests with absolute URL.
+// URL.RawPath does not do this, but RawPath must be a valid escaping of Path
+// or url.EscapedPath will ignore the RawPath escaping.
+//
+// Test `TestStandaloneSign` provides a complete example of using the signer
+// outside of the SDK and pre-escaping the URI path.

-// with changes:
-//   * using different headers for sign/presign
-
-// Package v4 implements the AWS signature version 4 algorithm (commonly known
-// as SigV4).
-//
-// For more information about SigV4, see [Signing AWS API requests] in the IAM
-// user guide.
-//
-// While this implementation CAN work in an external context, it is developed
-// primarily for SDK use and you may encounter fringe behaviors around header
-// canonicalization.
-//
-// # Pre-escaping a request URI
-//
-// AWS v4 signature validation requires that the canonical string's URI path
-// component must be the escaped form of the HTTP request's path.
-//
-// The Go HTTP client will perform escaping automatically on the HTTP request.
-// This may cause signature validation errors because the request differs from
-// the URI path or query from which the signature was generated.
-//
-// Because of this, we recommend that you explicitly escape the request when
-// using this signer outside of the SDK to prevent possible signature mismatch.
-// This can be done by setting URL.Opaque on the request. The signer will
-// prefer that value, falling back to the return of URL.EscapedPath if unset.
-//
-// When setting URL.Opaque you must do so in the form of:
-//
-//	"//<hostname>/<path>"
-//
-//	// e.g.
-//	"//example.com/some/path"
-//
-// The leading "//" and hostname are required or the escaping will not work
-// correctly.
-//
-// The TestStandaloneSign unit test provides a complete example of using the
-// signer outside of the SDK and pre-escaping the URI path.
