What is a Hash?

A cryptographic hash function takes input data and produces a fixed-size output (the hash or digest). The same input always produces the same hash, but even a tiny change in input produces a completely different hash. Hashes are one-way functions - you cannot reverse a hash to get the original data.

Supported Algorithms

  • •MD5: 128-bit hash (32 hex characters). Fast but considered cryptographically broken.
  • •SHA-1: 160-bit hash (40 hex characters). Deprecated for security use.
  • •SHA-256: 256-bit hash (64 hex characters). Widely used and secure.
  • •SHA-384: 384-bit hash (96 hex characters). Higher security margin.
  • •SHA-512: 512-bit hash (128 hex characters). Highest security.

Common Use Cases

  • •File Integrity: Verify files haven't been modified
  • •Password Storage: Store hashes instead of plain passwords
  • •Digital Signatures: Sign documents and verify authenticity
  • •Data Deduplication: Identify duplicate content
  • •Caching: Generate cache keys from content

Security Considerations

For security-critical applications, use SHA-256 or higher. MD5 and SHA-1 have known vulnerabilities and should only be used for non-security purposes like checksums. For password hashing, use specialized algorithms like bcrypt or Argon2 instead of plain SHA hashes.

100% Private

All hashing is performed locally in your browser using the Web Crypto API (for SHA algorithms) and JavaScript (for MD5). Your input text never leaves your device.
