## What it is
A Rust library implementing hash-based post-quantum digital signatures (WOTS+ and SHRINCS primitives) with an account policy wrapper. It compiles to WebAssembly via wasm-bindgen with a TypeScript npm package and includes Solana program integration.

## Use cases
- sign and verify messages with post-quantum hash-based signatures
- generate SHRINCS keypairs in JavaScript or TypeScript via WASM
- integrate quantum-resistant signatures into a Solana program
- verify post-quantum signatures in the browser
- import and export signing keys in a Node.js application

## When to choose
- you need signatures resistant to quantum attacks based on hash functions
- you are building on Solana and need post-quantum signature verification on-chain
- you want to use the same signature primitives across Rust, Node.js, and the browser via WASM

## When to avoid
- you need conventional signatures like Ed25519 or ECDSA with small signature sizes
- you need a standardized NIST signature scheme such as ML-DSA or SLH-DSA
- your license requirements are incompatible with AGPL-3.0
