Secure Implementation

Core Principles

Input Validation

• Validate input data before hashing
• Handle variable-length inputs correctly
• Implement maximum input size limits
• Sanitize inputs to prevent injection attacks

Output Handling

• Store complete hash output without truncation
• Use constant-time comparison for hash verification
• Implement secure error handling
• Avoid exposing internal hash state

Performance Optimization

• Use hardware acceleration when available
• Implement batch processing for multiple hashes
• Consider parallel processing for large datasets
• Profile and optimize critical paths

Security Considerations

• Use cryptographically secure random number generators
• Implement replay attack prevention
• Consider timing attack mitigations
• Regular security audits and updates
