About the Hash Generator

This free online hash generator computes cryptographic hash digests from any text input. It supports SHA-1, SHA-256, SHA-384, and SHA-512 via the browser's native SubtleCrypto API, plus MD5 for legacy compatibility.


All hashing runs entirely in your browser — no data is sent to any server. Hash functions are one-way: they produce a fixed-length fingerprint of your input that cannot be reversed. This makes them ideal for data integrity verification, checksums, and password storage workflows.

How to Generate Hashes

  1. Enter Text: Type or paste the text you want to hash.
  2. Select Algorithms: Toggle which hash algorithms to compute.
  3. Generate: Click "Generate Hashes" to compute all selected digests.
  4. Copy: Click the copy icon next to any hash value.

Algorithm Reference

  • MD5: 128-bit hash. Legacy use only — not cryptographically secure.
  • SHA-1: 160-bit hash. Deprecated for security but still common.
  • SHA-256: 256-bit hash. Industry standard for integrity checks.
  • SHA-512: 512-bit hash. Maximum security for critical applications.
