Undergraduate thesis produced to obtain a B.Sc. in Computer Science from UFSC, in which we optimize the Winternitz one-time signature scheme.

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.

Misuse-resistant hash-based signatures using deep Merkle trees

Explores and evaluates optimizations for the hash-based signature schemes XMSS, LMS, and SPHINCS+ in BouncyCastle. Integrates hardware acceleration and other software optimizations and provides benchmark tooling and results.
