WebNote: All SIGHASH types sign the transaction nLocktime field. In addition, the SIGHASH type itself is appended to the transaction before it is signed, so that it can't be modified once signed. In the example of Alice's transaction, we saw that the last part of the DER-encoded signature was 01, which is the SIGHASH_ALL flag. WebThe following are 4 code examples of bitcoin.core.script.SignatureHash().You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example.

WebNov 19, 2024 · The signed data is determined by a SigHash type which is specified by a byte that is appended to the digital signature. For the most common SigHash type, SIGHASH_ALL, the signed data consists of the transaction data with the scriptSigs replaced by the byte 0x00. The exception being the input corresponding program being executed.

WebAccording to the sighash type (ALL, NONE, SINGLE, ANYONECANPAY), a transaction digest is generated with a double SHA256 of a serialized subset of the transaction, and the signature is verified against this digest with a given public key. The detailed procedure is described in a Bitcoin Wiki article.
