 FibroHash is an enterprise-grade, cryptographically secure password generation framework designed specifically for system administrators and security professionals. Unlike traditional password generators that rely on simple randomization, FibroHash implements a novel multi-layered cryptographic approach combining PBKDF2 key derivation, HMAC-based entropy generation, and Fibonacci-inspired algorithmic patterns to produce passwords with guaranteed entropy levels exceeding 190 bits.
 
-The framework addresses critical security gaps in existing password generation tools by implementing proper cryptographic salt handling, resistance to timing attacks, and compliance with modern security standards including NIST SP 800-63B, PCI DSS, and ISO/IEC 27001. FibroHash operates entirely offline using only Python's standard library, ensuring no external dependencies or network communications that could compromise security.

 # Statement of need
 
-System administrators and security professionals require password generation tools that provide both high entropy and reproducible security analysis. Existing solutions often suffer from predictable patterns [@wheeler2005secure], insufficient entropy [@bonneau2012quest], or lack proper cryptographic foundations [@florencio2007large]. Many tools also require external dependencies or network connectivity, introducing potential security vulnerabilities [@gaw2006password].
+System administrators and security professionals require password generation tools that provide both high entropy and reproducible security analysis. Existing solutions often suffer from predictable patterns, insufficient entropy, or lack proper cryptographic foundations. Recent research on password behavior through persuasion techniques [@paudel2024priming] demonstrates the importance of user-centered approaches to secure password creation. Many tools also require external dependencies or network connectivity, introducing potential security vulnerabilities, while contemporary studies on password manager adoption [@tian2025unraveling] reveal ongoing challenges in organizational credential management practices. Recent analysis of password hashing methods using CSPRNG and PBKDF2 [@mustafa2024analysis] demonstrates the critical importance of implementing proper cryptographic foundations in password generation tools.
