Wilmer Paulino	545bc5d474	txscript: handle variable length P2PKH signatures in ComputePkScript ... Since P2PKH signatures have variable lengths, we would attempt to parse P2PKH scripts as P2SH if they didn't fit the previous length constraints.	2019-06-03 13:55:24 -07:00
Wilmer Paulino	0cec774a75	txscript: add support to re-derive output's PkScript from input ... In this commit, we extend the txscript package to support re-deriving the PkScript of an output by looking at the input's signature script/witness attempting to spend it. As of this commit, the only supported types are P2SH, v0 P2WSH, and v0 P2WPKH. This will serve useful to detect when a particular script has been spent on-chain. A set of test vectors has also been added for the supported script types to ensure its correctness.	2019-01-11 18:30:42 -08:00
