NSign (/ˈensaɪn/) is a set of .Net libraries for HTTP Message Signatures (RFC 9421).
eXtended signatures
cryptographic signatures directly from your keyboard
File Fingerprinting
Lightweight PHP library for cryptographically signed tokens with expiration. Stateless authentication without external dependencies
Hometree is a library for building homomorphic merkle trees for fast cryptographic signing and integrity checking of components in a finite set.
This repository implements the Lamport-Diffie One-Time Signature (OTS) scheme, a cryptographic protocol that enables secure, one-time signing of messages. Using SHA-256 hashing, the system generates a unique signature for each bit of a message, ensuring that each signature can only be used once.
