# BIP-322

Implements

[BIP-322](https://github.com/bitcoin/bips/blob/master/bip-0322.mediawiki),

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. 

- [x] simple

- [x] full 

- [ ] full (proof-of-funds)

- [ ] legacy (BIP-137)

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

[this](https://github.com/ACken2/bip322-js/tree/main) Javascript library.

## Test Vectors

- from Bitcoin Core [repo](https://github.com/bitcoin/bitcoin/blob/29b28d07fa958b89e1c7916fda5d8654474cf495/src/test/util_tests.cpp#L2747)

- from [bip322-js](https://github.com/ACken2/bip322-js/blob/main/test/Verifier.test.ts)

- from [BIP-322](https://github.com/bitcoin/bips/blob/master/bip-0322.mediawiki#test-vectors)

## 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](https://bip322.rs) site also runs a small WASM binary if you'd like

to check it out.

## MSRV

At the moment the Minimum Supported Rust Version (MSRV) is 1.63. You can check

it by running `just msrv`.
