SHA-256
256-bit hash (recommended)
SHA-384
384-bit hash
SHA-512
512-bit hash

Hash Security

  • SHA-256/512: Cryptographically secure, recommended
  • SHA-1: Deprecated for security, use for compatibility only
  • MD5: Not secure, use only for data integrity checks
  • • Hashes are one-way functions (irreversible)
  • • Same input always produces same hash
  • • Small changes result in completely different hashes

Use Cases

  • • File integrity verification and checksums
  • • Password storage and authentication
  • • Digital signatures and certificates
  • • Blockchain and cryptocurrency operations
  • • Data deduplication in storage systems
  • • Version control and commit identification
