Functions ¶
func BlockHash ¶
func BlockHash(block *external.DomainBlock) *external.DomainHash
BlockHash returns the given block's hash
func CalculateSignatureHashECDSA ¶
func CalculateSignatureHashECDSA(tx *external.DomainTransaction, inputIndex int, hashType SigHashType, reusedValues *SighashReusedValues) (*external.DomainHash, error)
CalculateSignatureHashECDSA will, given a script and hash type calculate the signature hash to be used for signing and verification for ECDSA. This returns error only if one of the provided parameters are consensus-invalid.
func CalculateSignatureHashSchnorr ¶
func CalculateSignatureHashSchnorr(tx *external.DomainTransaction, inputIndex int, hashType SigHashType, reusedValues *SighashReusedValues) (*external.DomainHash, error)
CalculateSignatureHashSchnorr will, given a script and hash type calculate the signature hash to be used for signing and verification for Schnorr. This returns error only if one of the provided parameters are consensus-invalid.
func HeaderHash ¶
func HeaderHash(header external.BaseBlockHeader) *external.DomainHash
HeaderHash returns the given header's hash
func TransactionHash ¶
func TransactionHash(tx *external.DomainTransaction) *external.DomainHash
TransactionHash returns the transaction hash.
func TransactionID ¶
func TransactionID(tx *external.DomainTransaction) *external.DomainTransactionID
TransactionID generates the Hash for the transaction without the signature script and payload field.
func TransactionIDs ¶
func TransactionIDs(txs []*external.DomainTransaction) []*external.DomainTransactionID
TransactionIDs converts the provided slice of DomainTransactions to a corresponding slice of TransactionIDs
Types ¶
type SigHashType ¶
type SigHashType uint8
SigHashType represents hash type bits at the end of a signature.
const ( SigHashAll SigHashType = 0b00000001 SigHashNone SigHashType = 0b00000010 SigHashSingle SigHashType = 0b00000100 SigHashAnyOneCanPay SigHashType = 0b10000000 // SigHashMask defines the number of bits of the hash type which is used // to identify which outputs are signed. SigHashMask = 0b00000111 )
Hash type bits from the end of a signature.
func (SigHashType) IsStandardSigHashType ¶
func (sht SigHashType) IsStandardSigHashType() bool
IsStandardSigHashType returns true if sht represents a standard SigHashType
type SighashReusedValues ¶
type SighashReusedValues struct {
// contains filtered or unexported fields
}
SighashReusedValues holds all fields used in the calculation of a transaction's sigHash, that are the same for all transaction inputs. Reuse of such values prevents the quadratic hashing problem.
