Types

type MultiSignatureData 

type MultiSignatureData struct {
	// BitArray is a compact way of indicating which signers from the multisig key
	// have signed
	BitArray *types.CompactBitArray

	// Signatures is the nested SignatureData's for each signer
	Signatures []SignatureData
}

MultiSignatureData represents the nested SignatureData of a multisig signature

type SignMode 

type SignMode int32

SignMode represents a signing mode with its own security guarantees.

This enum should be considered a registry of all known sign modes in the Cosmos ecosystem. Apps are not expected to support all known sign modes. Apps that would like to support custom sign modes are encouraged to open a small PR against this file to add a new case to this SignMode enum describing their sign mode so that different apps have a consistent version of this enum. 

const (
	// SIGN_MODE_UNSPECIFIED specifies an unknown signing mode and will be
	// rejected.
	SignMode_SIGN_MODE_UNSPECIFIED SignMode = 0
	// SIGN_MODE_DIRECT specifies a signing mode which uses SignDoc and is
	// verified with raw bytes from Tx.
	SignMode_SIGN_MODE_DIRECT SignMode = 1
	// SIGN_MODE_TEXTUAL is a future signing mode that will verify some
	// human-readable textual representation on top of the binary representation
	// from SIGN_MODE_DIRECT. It is currently not supported.
	SignMode_SIGN_MODE_TEXTUAL SignMode = 2
	// SIGN_MODE_DIRECT_AUX specifies a signing mode which uses
	// SignDocDirectAux. As opposed to SIGN_MODE_DIRECT, this sign mode does not
	// require signers signing over other signers' `signer_info`. It also allows
	// for adding Tips in transactions.
	//
	// Since: cosmos-sdk 0.46
	SignMode_SIGN_MODE_DIRECT_AUX SignMode = 3
	// SIGN_MODE_LEGACY_AMINO_JSON is a backwards compatibility mode which uses
	// Amino JSON and will be removed in the future.
	SignMode_SIGN_MODE_LEGACY_AMINO_JSON SignMode = 127
	// SIGN_MODE_EIP_191 specifies the sign mode for EIP 191 signing on the Cosmos
	// SDK. Ref: https://eips.ethereum.org/EIPS/eip-191
	//
	// Currently, SIGN_MODE_EIP_191 is registered as a SignMode enum variant,
	// but is not implemented on the SDK by default. To enable EIP-191, you need
	// to pass a custom `TxConfig` that has an implementation of
	// `SignModeHandler` for EIP-191. The SDK may decide to fully support
	// EIP-191 in the future.
	//
	// Since: cosmos-sdk 0.45.2
	SignMode_SIGN_MODE_EIP_191 SignMode = 191
)

func (SignMode) String 

func (x SignMode) String() string

type SignatureData 

type SignatureData interface {
	// contains filtered or unexported methods
}

SignatureData represents either a *SingleSignatureData or *MultiSignatureData. It is a convenience type that is easier to use in business logic than the encoded protobuf ModeInfo's and raw signatures.

func SignatureDataFromProto 

func SignatureDataFromProto(descData *SignatureDescriptor_Data) SignatureData

SignatureDataFromProto converts a SignatureDescriptor_Data to SignatureData. SignatureDescriptor_Data is considered an encoding type whereas SignatureData is used for business logic.

type SignatureDescriptor 

type SignatureDescriptor struct {
	// public_key is the public key of the signer
	PublicKey *types.Any                `protobuf:"bytes,1,opt,name=public_key,json=publicKey,proto3" json:"public_key,omitempty"`
	Data      *SignatureDescriptor_Data `protobuf:"bytes,2,opt,name=data,proto3" json:"data,omitempty"`
	// sequence is the sequence of the account, which describes the
	// number of committed transactions signed by a given address. It is used to prevent
	// replay attacks.
	Sequence uint64 `protobuf:"varint,3,opt,name=sequence,proto3" json:"sequence,omitempty"`
}

SignatureDescriptor is a convenience type which represents the full data for a signature including the public key of the signer, signing modes and the signature itself. It is primarily used for coordinating signatures between clients.

type SignatureV2 

type SignatureV2 struct {
	// PubKey is the public key to use for verifying the signature
	PubKey cryptotypes.PubKey

	// Data is the actual data of the signature which includes SignMode's and
	// the signatures themselves for either single or multi-signatures.
	Data SignatureData

	// Sequence is the sequence of this account. Only populated in
	// SIGN_MODE_DIRECT.
	Sequence uint64
}

SignatureV2 is a convenience type that is easier to use in application logic than the protobuf SignerInfo's and raw signature bytes. It goes beyond the first sdk.Signature types by supporting sign modes and explicitly nested multi-signatures. It is intended to be used for both building and verifying signatures.

type SingleSignatureData 

type SingleSignatureData struct {
	// SignMode represents the SignMode of the signature
	SignMode SignMode

	// Signature is the raw signature.
	Signature []byte
}

SingleSignatureData represents the signature and SignMode of a single (non-multisig) signer
