Module breez_sdk_core::bitcoin::util::sighash

Generalized, efficient, signature hash implementation.

Implementation of the algorithm to compute the message to be signed according to Bip341, Bip143 and legacy (before Bip143).

Structs

• Annex
  The Annex struct is a slice wrapper enforcing first byte is 0x50.
• ScriptPath
  Information related to the script path spending.
• SighashCache
  Efficiently calculates signature hash message for legacy, segwit and taproot inputs.
• SighashTypeParseError
  Error returned for failure during parsing one of the sighash types.

Enums

• EcdsaSighashType
  Hashtype of an input’s signature, encoded in the last byte of the signature.
• Error
  Possible errors in computing the signature message.
• Prevouts
  Contains outputs of previous transactions. In the case SchnorrSighashType variant is SIGHASH_ANYONECANPAY, Prevouts::One may be used.
• SchnorrSighashType
  Hashtype of an input’s signature, encoded in the last byte of the signature. Fixed values so they can be cast as integer types for encoding.
