+# FibroHash - Enterprise-Grade Secure Password Generator
+
+`FibroHash` is a cryptographically secure password generator that combines advanced mathematical concepts with modern security practices. It uses cryptographic Fibonacci-based algorithms, PBKDF2 key derivation, and multiple entropy sources to generate highly secure, unpredictable passwords suitable for enterprise environments.
+
+## 🔐 Security Features
+
+- **Cryptographic Security**: Uses `secrets` module for cryptographically secure random number generation
+- **PBKDF2 Key Derivation**: Industry-standard key derivation with configurable iterations
+- **Multiple Entropy Sources**: Combines user input, cryptographic salts, and Fibonacci-based algorithms
+- **Input Validation**: Comprehensive sanitization and validation of all inputs
+- **Timing Attack Resistance**: Constant-time operations where possible
+- **Character Diversity Enforcement**: Ensures passwords meet complexity requirements
+- **Configurable Security Levels**: Standard, High, and Maximum security modes
+- **Security Auditing**: Built-in password quality analysis and compliance checking
+
+## 🔬 How It Works
+
+FibroHash employs a multi-layered security approach:
+
+1. **Input Processing**: User input is validated, sanitized, and processed through PBKDF2 with cryptographic salt
+2. **Cryptographic Fibonacci Generation**: Creates large numbers using HMAC-SHA256 in a Fibonacci-inspired pattern
+3. **Multi-Round Generation**: Generates password segments through multiple cryptographic rounds
+4. **Entropy Mixing**: Combines multiple entropy sources using secure cryptographic operations
+5. **Character Encoding**: Maps numeric values to characters using a secure base conversion system
+6. **Quality Assurance**: Validates output for character diversity and security compliance
+
+### Security Architecture
+
+```
+User Input → Input Validation → PBKDF2 + Salt → Multi-Round Generation
+                                                         ↓
+Password ← Character Encoding ← Entropy Mixing ← Crypto-Fibonacci
+```
+
+## 📋 System Requirements
+
+- **Python**: 3.7 or higher
+- **Dependencies**: Standard library only (no external dependencies)
+- **Platforms**: Cross-platform (Windows, macOS, Linux)
+- **Memory**: Minimal footprint (~1MB)
+- **Performance**: Optimized for security over speed
+
+## 🚀 Installation & Quick Start
+
+### Prerequisites
+

+
+```bash
+python --version  # Should be 3.7 or higher
+```
+
+### Installation
+
+1. **Clone the repository**:
+   ```bash
+   git clone https://github.com/SpyrosLefkaditis/fibrohash.git
+   cd fibrohash

+
+# Generate with custom parameters
+password = generate_password("my phrase", password_length=16, security_level="maximum")
+```
+
+
+
+
+## 🔧 Configuration

+      "high": 5000,
+      "maximum": 10000
+    }
+  }
+}
+```
+

+## 🛡️ Security Best Practices
+
+### For Users
+- **Use unique input phrases** for different services
+- **Store generated passwords securely** (password manager recommended)
+- **Don't share passwords** via unsecured channels
+- **Regenerate passwords periodically** for high-security accounts
+- **Use maximum security level** for critical systems
+
+### For Developers
+- **Review security configuration** before deployment
+- **Monitor for security updates** to dependencies
+- **Implement proper logging** for security events
+- **Test with your security requirements** using provided tools
+- **Consider hardware security modules** for enterprise deployments
+
+### Input Recommendations
+- **Length**: 8+ characters provide better entropy mixing
+- **Complexity**: Mix of letters, numbers, symbols in input
+- **Uniqueness**: Use different phrases for different passwords
+- **Avoid**: Personal information, dictionary words, patterns
+
+## 🔍 Security Audit & Compliance
+
+### Standards Compliance
+- ✅ **NIST SP 800-63B**: Password composition guidelines
+- ✅ **PCI DSS**: Payment card industry requirements
+- ✅ **ISO/IEC 27001**: Information security management
+- ✅ **OWASP**: Web application security best practices
+
+### Regular Security Testing

+# Run comprehensive security test suite
+python test.py
+
+# Generate security audit report

+
+## 🚨 Security Considerations
+
+### What FibroHash Does NOT Do
+- **Store passwords**: All generation is stateless
+- **Network communication**: Fully offline operation
+- **Log sensitive data**: Input phrases are not logged
+- **Guarantee uniqueness**: Use different inputs for different passwords
+
+### Threat Model
+FibroHash is designed to resist:
+- 🔐 **Brute force attacks**: High entropy output
+- ⚡ **Timing attacks**: Consistent operation times
+- 🎯 **Pattern analysis**: Cryptographic randomness
+- 📊 **Statistical analysis**: Multiple entropy sources
+- 🔍 **Input prediction**: PBKDF2 with salt
