service/meta.proto

Message RequestMetaHeader

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

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

Message Token.Info

Field	Type	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

Scalar Value Types

.proto Type	Notes	C++ Type	Java Type	Python Type
double		double	double	float
float		float	float	float
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
int64	Uses variable-length encoding. Inefficient for encoding negative numbers – if your field is likely to have negative values, use sint64 instead.	int64	long	int/long
uint32	Uses variable-length encoding.	uint32	int	int/long
uint64	Uses variable-length encoding.	uint64	long	int/long
sint32	Uses variable-length encoding. Signed int value. These more efficiently encode negative numbers than regular int32s.	int32	int	int
sint64	Uses variable-length encoding. Signed int value. These more efficiently encode negative numbers than regular int64s.	int64	long	int/long
fixed32	Always four bytes. More efficient than uint32 if values are often greater than 2^28.	uint32	int	int
fixed64	Always eight bytes. More efficient than uint64 if values are often greater than 2^56.	uint64	long	int/long
sfixed32	Always four bytes.	int32	int	int
sfixed64	Always eight bytes.	int64	long	int/long
bool		bool	boolean	boolean
string	A string must always contain UTF-8 encoded or 7-bit ASCII text.	string	String	str/unicode
bytes	May contain any arbitrary sequence of bytes.	string	ByteString	str
