Hash Types

Hash Information

Cryptographic Hashes

  • SHA-256, SHA-512: Secure and widely used
  • SHA-3: Latest standard, very secure
  • BLAKE2: Fast and secure alternative
  • Used for password storage, digital signatures

Legacy Hashes

  • MD5, SHA-1: Deprecated, not secure
  • Vulnerable to collision attacks
  • Should not be used for security
  • Only for compatibility or non-security uses

Non-Cryptographic

  • CRC32: Error detection, not security
  • FNV, MurmurHash: Fast hashing
  • XXH: Extremely fast hashing
  • Used for hash tables, checksums

Hash Security Tips

Secure Hashing

  • Use SHA-256 or SHA-512 for security
  • Always use salt for password hashing
  • Use multiple iterations (PBKDF2, bcrypt)
  • Never use MD5 or SHA-1 for security

Password Hashing

  • Use bcrypt, scrypt, or Argon2
  • Include random salt for each password
  • Use high iteration counts
  • Consider using dedicated libraries

Common Mistakes

  • Using weak hash functions
  • Not using salt
  • Using too few iterations
  • Storing hashes in plain text
