SHA-1 Security Information & Alternatives
🚨 Security Warning
SHA-1 is cryptographically weak and vulnerable to collision attacks. While still used in some legacy systems, it should be avoided for new security implementations.
⚠️ SHA-1 Vulnerabilities
- Collision attacks demonstrated in 2017
- Rainbow table attacks possible
- No built-in salt support
- Not suitable for password hashing
✅ Secure Alternatives
- BCrypt: Industry standard for passwords
- Argon2: Modern, memory-hard function
- SHA-256/SHA-512: Stronger hash functions
- HMAC-SHA256: For message authentication
📋 Acceptable Use Cases
- Git commit hashes (being phased out)
- Legacy system compatibility
- Non-security file checksums
- Educational purposes
🔄 Migration Recommendations
- Upgrade to SHA-256 or SHA-512
