hashsigs-rs

A Rust implementation of WOTS+ (Winternitz One-Time Signature) scheme, with Solana program support.

Building

To build the library:

cargo build

For release build:

cargo build --release

To build the Solana program:

cd solana
cargo build-sbf

Testing

Run all tests:

cargo test

Run specific test vectors:

cargo test test_wotsplus_keccak256_vectors

Run Solana program tests:

cd solana
cargo test-sbf

For test output and backtrace:

RUST_BACKTRACE=1 cargo test-sbf -- --nocapture 2>&1

Show compute units only:

RUST_BACKTRACE=1 cargo test-sbf -- --nocapture 2>&1 | grep "compute units:"

Development Requirements

• Rust 1.70 or later
• Solana CLI tools (for Solana program development): https://solana.com/docs/intro/installation

NOTE: if on Mac, do not use brew to install rust and instead use https://www.rust-lang.org/tools/install
