What are Cryptographic Hashes?

Cryptographic hash functions are mathematical algorithms that convert input data of any size into a fixed-size string of characters. The output, called a hash or digest, is unique to the input data. Even a tiny change in the input produces a completely different hash, making them ideal for verifying data integrity and detecting tampering.

Supported Hash Algorithms

  • MD5: 128-bit hash function, widely used for checksums (not recommended for security)
  • SHA-1: 160-bit hash function, formerly used in SSL/TLS (deprecated for security)
  • SHA-256: 256-bit hash from the SHA-2 family, widely used and secure
  • SHA-512: 512-bit hash from the SHA-2 family, maximum security
  • HMAC: Hash-based Message Authentication Code using a secret key

Common Use Cases

  • Verify file integrity and detect corruption
  • Generate checksums for software downloads
  • Create secure password hashes
  • Implement digital signatures
  • Validate data transmission integrity
  • Generate unique identifiers for data
  • Create HMAC tokens for API authentication

Privacy & Security

All hash generation happens locally in your browser. Your data never leaves your device, ensuring complete privacy and security. No server-side processing, no data storage, no tracking.
