Module sapio_bitcoin::util::sighash

Expand description

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 to be 0x50.
ScriptPath
Information related to the script path spending
SighashCache
Efficiently calculates signature hash message for legacy, segwit and taproot inputs.

Enums

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