Algorithm Information

bcrypt Recommended

Industry standard for password hashing. Adaptive and designed to be slow.

  • ✅ Adaptive cost parameter
  • ✅ Built-in salt
  • ✅ Widely supported
  • ✅ Time-tested security

Argon2 Modern

Winner of the Password Hashing Competition. Most secure option available.

  • ✅ Memory-hard function
  • ✅ Resistant to GPU attacks
  • ✅ Multiple variants (2i, 2d, 2id)
  • ✅ Latest standard

MD5/SHA1 Deprecated

Fast cryptographic hashes, but not suitable for passwords.

  • ❌ Too fast (vulnerable to brute force)
  • ❌ No built-in salt
  • ❌ Collision vulnerabilities
  • ⚠️ Use only for legacy compatibility
