 FibroHash is a research-focused, cryptographically secure password generation framework designed for system administrators and security professionals. It implements a novel multi-layered cryptographic approach combining PBKDF2 key derivation, HMAC-based entropy generation, and mathematical sequence algorithms to produce passwords with guaranteed entropy levels exceeding 190 bits.
