Functions ¶
func VerifySignature ¶
func VerifySignature(pubKey cryptotypes.PubKey, signerData SignerData, sigData signing.SignatureData, handler SignModeHandler, tx sdk.Tx) error
VerifySignature verifies a transaction signature contained in SignatureData abstracting over different signing modes and single vs multi-signatures.
Types ¶
type SigVerifiableTx ¶
type SigVerifiableTx interface {
types.Tx
GetSigners() []types.AccAddress
GetPubKeys() ([]cryptotypes.PubKey, error) // If signer already has pubkey in context, this list will have nil in its place
GetSignaturesV2() ([]signing.SignatureV2, error)
}
SigVerifiableTx defines a transaction interface for all signature verification handlers.
type SignModeHandler ¶
type SignModeHandler interface {
// DefaultMode is the default mode that is to be used with this handler if no
// other mode is specified. This can be useful for testing and CLI usage
DefaultMode() signing.SignMode
// Modes is the list of modes supporting by this handler
Modes() []signing.SignMode
// GetSignBytes returns the sign bytes for the provided SignMode, SignerData and Tx,
// or an error
GetSignBytes(mode signing.SignMode, data SignerData, tx sdk.Tx) ([]byte, error)
}
SignModeHandler defines a interface to be implemented by types which will handle SignMode's by generating sign bytes from a Tx and SignerData
type SignModeHandlerMap ¶
type SignModeHandlerMap struct {
// contains filtered or unexported fields
}
SignModeHandlerMap is SignModeHandler that aggregates multiple SignModeHandler's into a single handler
func NewSignModeHandlerMap ¶
func NewSignModeHandlerMap(defaultMode signing.SignMode, handlers []SignModeHandler) SignModeHandlerMap
NewSignModeHandlerMap returns a new SignModeHandlerMap with the provided defaultMode and handlers
func (SignModeHandlerMap) DefaultMode ¶
func (h SignModeHandlerMap) DefaultMode() signing.SignMode
DefaultMode implements SignModeHandler.DefaultMode
func (SignModeHandlerMap) GetSignBytes ¶
func (h SignModeHandlerMap) GetSignBytes(mode signing.SignMode, data SignerData, tx sdk.Tx) ([]byte, error)
DefaultMode implements SignModeHandler.GetSignBytes
func (SignModeHandlerMap) Modes ¶
func (h SignModeHandlerMap) Modes() []signing.SignMode
Modes implements SignModeHandler.Modes
type SignerData ¶
type SignerData struct {
// The address of the signer.
//
// In case of multisigs, this should be the multisig's address.
Address string
// ChainID is the chain that this transaction is targeted
ChainID string
// AccountNumber is the account number of the signer.
//
// In case of multisigs, this should be the multisig account number.
AccountNumber uint64
// Sequence is the account sequence number of the signer that is used
// for replay protection. This field is only useful for Legacy Amino signing,
// since in SIGN_MODE_DIRECT the account sequence is already in the signer
// info.
//
// In case of multisigs, this should be the multisig account number.
Sequence uint64
// PubKey is the public key of the signer.
//
// In case of multisigs, this should be the pubkey of the member of the
// multisig that is signing the current sign doc.
PubKey cryptotypes.PubKey
}
SignerData is the specific information needed to sign a transaction that generally isn't included in the transaction body itself
type Tx ¶
type Tx interface {
SigVerifiableTx
types.TxWithMemo
types.FeeTx
tx.TipTx
types.TxWithTimeoutHeight
}
Tx defines a transaction interface that supports all standard message, signature fee, memo, tips, and auxiliary interfaces.
