đŸ’ģ Implementation Security
0/12 Issues
Use Cryptographically Secure Libraries
Verify that SHA-224 implementation uses well-vetted cryptographic libraries (e.g., OpenSSL, WebCrypto, hashlib) rather than custom implementations.
Critical OWASP A02 CWE-327
Constant-Time Implementation
Ensure the implementation runs in constant time to prevent timing attacks. Avoid data-dependent branches and memory access patterns.
High Side-Channel CWE-208
Library Version Management
Keep cryptographic libraries updated to the latest stable versions. Subscribe to security advisories for the libraries in use.
High OWASP A06 Patch Management
Error Handling
Implement proper error handling that doesn't leak sensitive information. Log errors securely without exposing hash inputs or outputs.
Medium OWASP A09 CWE-209
Input Validation
Validate all inputs before hashing. Check for maximum sizes, encoding issues, and null bytes that could cause problems.
Medium Input Sanitization CWE-20
🔐 Cryptographic Security
0/10 Issues
No Password Storage with Plain SHA-224
Never use plain SHA-224 for password storage. Use proper password hashing functions like bcrypt, scrypt, or Argon2 instead.
Critical OWASP A02 CWE-916
Salt Usage for Sensitive Data
When hashing sensitive data, use proper salting techniques. Generate cryptographically secure random salts of at least 128 bits.
High Rainbow Tables CWE-759
HMAC for Authentication
Use HMAC-SHA224 instead of plain SHA-224 when message authentication is required. Never use secret prefix/suffix constructions.
High MAC Security CWE-328
Collision Resistance Assessment
Evaluate if SHA-224's 112-bit collision resistance is sufficient for your security requirements. Consider SHA-256 for higher security needs.
Medium Algorithm Selection Risk Assessment
📊 Data Handling & Storage
0/8 Issues
Secure Memory Management
Clear sensitive data from memory after use. Use secure memory wiping functions that prevent compiler optimization from removing the operation.
High Memory Security CWE-244
Encoding Consistency
Maintain consistent encoding (UTF-8, Base64, Hex) throughout the application. Document encoding requirements clearly.
Medium Data Integrity CWE-838
Hash Storage Security
Store hash values securely with appropriate access controls. Encrypt hashes at rest if they contain sensitive information.
Medium Storage Security CWE-922
Audit Logging
Implement comprehensive audit logging for hash operations. Log who, what, when, and why without logging sensitive data.
Low Audit Trail Compliance
📋 Compliance & Standards
0/7 Issues
FIPS 140-2 Compliance
Verify that the SHA-224 implementation meets FIPS 140-2 requirements if operating in a regulated environment.
High FIPS 140-2 Regulatory
GDPR Data Protection
Ensure hash usage complies with GDPR requirements. Document lawful basis for processing and implement appropriate technical measures.
Medium GDPR Privacy
PCI DSS Requirements
If handling payment card data, ensure SHA-224 usage meets PCI DSS cryptographic requirements (currently requires SHA-256 minimum).
Medium PCI DSS Payment Security
⚙ī¸ Operational Security
0/8 Issues
Performance Monitoring
Monitor hash operation performance for anomalies that could indicate attacks or system issues.
High Monitoring Operations
Backup and Recovery
Implement secure backup procedures for systems using SHA-224. Test recovery procedures regularly.
Medium Business Continuity DR Planning
Documentation
Maintain comprehensive documentation of SHA-224 usage, including use cases, data flows, and security considerations.
Low Documentation Knowledge Management
