BIP-322

Implements BIP-322, generic message signing and verification.

Types of Signatures

At the moment this crate supports P2TR, P2WPKH and P2SH-P2WPKH single-sig addresses. Feedback through issues or PRs on the interface design and security is welcome and encouraged.

• simple
• full
• full (proof-of-funds)
• legacy (BIP-137)

The goal is to provide a full signing and verifying library similar to this Javascript library.

Test Vectors

• from Bitcoin Core repo
• from bip322-js
• from BIP-322

Compile for WASM (on MacOs)

brew install llvm
cargo install wasm-pack
rustup target add wasm32-unknown-unknown
AR=/opt/homebrew/opt/llvm/bin/llvm-ar \
CC=/opt/homebrew/opt/llvm/bin/clang \
wasm-pack build \
    --target web \
    --out-name bip322 \
    www

The WASM binary and Javascript glue code can then be found in www/pkg. The bip322.rs site also runs a small WASM binary if you'd like to check it out.
