service/meta.proto

Message RequestMetaHeader

RequestMetaHeader contains information about request meta headers (should be embedded into message)

Field Type Label Description
TTL uint32 TTL must be larger than zero, it decreased in every NeoFS Node
Epoch uint64 Epoch for user can be empty, because node sets epoch to the actual value
Version uint32 Version defines protocol version TODO: not used for now, should be implemented in future
Raw bool Raw determines whether the request is raw or not

Message ResponseMetaHeader

ResponseMetaHeader contains meta information based on request processing by server (should be embedded into message)

Field Type Label Description
Epoch uint64 Current NeoFS epoch on server
Version uint32 Version defines protocol version TODO: not used for now, should be implemented in future

service/verify.proto

Message RequestVerificationHeader

RequestVerificationHeader is a set of signatures of every NeoFS Node that processed request (should be embedded into message).

Field Type Label Description
Signatures RequestVerificationHeader.Signature repeated Signatures is a set of signatures of every passed NeoFS Node
Token Token Token is a token of the session within which the request is sent

Message RequestVerificationHeader.Signature

Field Type Label Description
Sign bytes Sign is signature of the request or session key.
Peer bytes Peer is compressed public key used for signature.

Message Token

User token granting rights for object manipulation

Field Type Label Description
TokenInfo Token.Info Info is a grouped information about token
Signature bytes Signature is a signature of session token information

Message Token.Info

Field Type Label Description
ID bytes ID is a token identifier. valid UUIDv4 represented in bytes
OwnerID bytes OwnerID is an owner of manipulation object
verb Token.Info.Verb Verb is a type of request for which the token is issued
Address refs.Address Address is an object address for which token is issued
Created uint64 Created is an initial epoch of token lifetime
ValidUntil uint64 ValidUntil is a last epoch of token lifetime
SessionKey bytes SessionKey is a public key of session key

Token.Info.Verb

Verb is an enumeration of session request types

Name Number Description
Put 0 Put refers to object.Put RPC call
Get 1 Get refers to object.Get RPC call
Head 2 Head refers to object.Head RPC call
Search 3 Search refers to object.Search RPC call
Delete 4 Delete refers to object.Delete RPC call
Range 5 Range refers to object.GetRange RPC call
RangeHash 6 RangeHash refers to object.GetRangeHash RPC call

int32 Uses variable-length encoding. Inefficient for encoding negative numbers – if your field is likely to have negative values, use sint32 instead. int32 int int
