About MD6

MD6 (Message Digest 6) is a cryptographic hash function created by Ronald Rivest. It was designed as a successor to MD5 and incorporates features of modern hash functions while maintaining the simplicity of older algorithms. MD6 uses a tree-based structure, making it suitable for parallel computation on multi-core systems.

Unlike MD5, MD6 is designed to be secure against known cryptographic attacks. It supports variable output sizes (from 128 to 512 bits) and uses a keyed mode for message authentication. However, MD6 has not been widely adopted in practice, and SHA-2 and SHA-3 are more commonly used in modern applications.
