BIP 174 format playground

Small script that parses and regenerates variants of the BIP 174 scheme.

Requires Python 3 and construct. Protobuf is based on trezorlib implementation, extended to support Fixed32 fields. It doesn't support packed arrays though, which messes up the measurement a little.

Presumes UNIX-based environment, only tested on Linux but should work elsewhere too.

Installation and usage

Create and activate a virtualenv:

python3 -m venv virtualenv
source virtualenv/bin/activate
pip install -r requirements.txt

Feed one of the test vectors (taken from here) to the tool:

python3 analyze.py < case-sighash.hex
