About Hash Generator

A cryptographic hash function takes input data and produces a fixed-size string of bytes. The output is deterministic - the same input always produces the same hash.

Available Algorithms

  • SHA-1: 160-bit (40 hex characters) - legacy, not recommended for security
  • SHA-256: 256-bit (64 hex characters) - widely used, recommended
  • SHA-384: 384-bit (96 hex characters) - stronger variant
  • SHA-512: 512-bit (128 hex characters) - strongest variant

Common Uses

  • File integrity verification
  • Password storage (with salt)
  • Digital signatures
  • Data deduplication
  • Blockchain and cryptocurrency
