HashMaster is a powerful and easy-to-use tool for computing HMAC hashes of user-provided input strings using various hashing algorithms. With support for SHA-256, SHA-512, SHA-384 and SHA-224, HashMaster provides a flexible and secure way to verify the integrity and authenticity of messages in a wide range of applications.

Ancillary files for research done on a variant of the Winternitz one-time signature scheme.

Signature schemes implemented in different languages
