Hash Generator (MD5, SHA-1, SHA-256, SHA-512)


Generate cryptographic hashes from any text. Uses the Web Crypto API β€” nothing is sent to a server.

Supported Algorithms

  • MD5 β€” 128-bit hash. Fast but not collision-resistant. Use for checksums, not security.
  • SHA-1 β€” 160-bit hash. Deprecated for security but still used in legacy systems.
  • SHA-256 β€” 256-bit hash. Industry standard for security, certificates, and blockchain.
  • SHA-512 β€” 512-bit hash. Strongest option, used in high-security applications.

Common Use Cases

  • Verify file integrity (compare checksums)
  • Generate content hashes for caching
  • Create deterministic IDs from strings
  • Check if two strings are identical without comparing them directly
