hashsigs-ts is a TypeScript library that implements hash-based digital signatures using the WOTS+ scheme.
Hash-based signatures provide an alternative to traditional public-key cryptography by deriving signatures from cryptographic hash functions rather than number-theoretic problems. WOTS+ is a one-time signature scheme that offers strong security guarantees against quantum computing threats. The library implements this scheme in TypeScript, making hash-based signature generation and verification available to JavaScript environments. This approach is particularly valuable for applications requiring post-quantum cryptographic security, as hash-based signatures remain secure even against adversaries with quantum computers.
Developers should consider this library if their projects require quantum-resistant cryptography or operate in environments where traditional RSA and elliptic-curve signatures may become vulnerable. It suits applications handling long-term sensitive data, security-critical infrastructure, or compliance scenarios where post-quantum readiness is mandated. The TypeScript implementation makes it accessible to Node.js and browser-based applications. The library's focus on WOTS+ specifically targets use cases where one-time signatures are acceptable, such as certificate signing or scenarios where signature keys are used only once.
The project shows consistent maintenance with regular commits addressing implementation details and bug fixes. Development activity demonstrates ongoing refinement of the cryptographic implementation through iterative improvements. The codebase receives updates that suggest active attention to code quality and correctness in the sensitive domain of cryptographic operations.
