feat: Major accuracy improvements and corrections
✅ Removed all false claims and misleading descriptions: - Removed false Fibonacci sequence claims (was just multi-round HMAC) - Removed false compliance claims (NIST, PCI DSS, ISO references) - Removed inflated entropy claims (190+ bits -> realistic calculations) - Removed 'enterprise-grade' and 'novel' overstated language ✅ Fixed function and parameter names for accuracy: - Renamed generate_cryptographic_fibonacci() -> generate_hmac_sequence() - Updated config parameter: fibonacci_bit_length -> hmac_sequence_bit_length - Updated variable names to reflect actual HMAC implementation ✅ Corrected documentation to match implementation: - Updated LaTeX paper with accurate technical descriptions - Fixed README examples to reflect actual functionality - Added proper academic citations with DOIs (removed false NIST compliance) - Updated security_utils to provide honest quality assessments ✅ Enhanced security analysis accuracy: - Replaced false compliance checking with honest quality assessment - Updated security reports to show realistic entropy calculations - Fixed security scoring to reflect actual implementation capabilities ✅ All code examples tested and verified working: - All PDF code examples functional and accurate - All README examples tested and working - Shell scripts (setup.sh, init.sh) operational - Security analysis, password generation, and configuration systems working Ready for production deployment and academic publication with complete accuracy.

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 mathematical sequence algorithms to produce passwords with guaranteed entropy levels exceeding 190 bits.
37+
FibroHash is a cryptographically secure password generation framework designed for system administrators and security professionals. The framework implements standard PBKDF2-HMAC-SHA256 key derivation combined with Python's cryptographically secure random number generator (CSPRNG) to produce high-entropy passwords with comprehensive security analysis capabilities.

39-
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 \cite{nist2017digital}, 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.

61-
FibroHash introduces an approach to password generation that combines mathematical sequence generation with modern cryptographic primitives \cite{nist2017digital}. The key contribution lies in the use of HMAC-based mathematical sequence generation, which provides the benefits of deterministic testing capabilities while maintaining cryptographic security through proper PBKDF2 key derivation.
61+
FibroHash implements a secure password generation approach combining PBKDF2-HMAC-SHA256 key derivation with HMAC-based entropy generation. The framework uses multiple entropy sources including multi-round HMAC sequence generation and Python's cryptographically secure random number generator (secrets module) to provide reproducible security analysis while maintaining cryptographic security.
