About the Hash Generator (SHA-256, SHA-512)

Compute SHA-1, SHA-256, SHA-384 and SHA-512 hashes of any text instantly using the browser's native Web Crypto API — the same audited implementation your browser uses for TLS.

Hashes verify integrity, deduplicate content and fingerprint data; local computation means sensitive input never leaves your machine.

How to use the Hash Generator (SHA-256, SHA-512)

  1. Paste or type your text.
  2. All four hashes compute automatically.
  3. Click any hash to copy it.

Common uses

Verifying file/text integrity Generating deterministic IDs Comparing content without exposing it

Frequently asked questions

Which algorithm should I use?
SHA-256 is the modern default. SHA-1 is provided for legacy comparison only — it is broken for security purposes.
Can a hash be reversed?
No — hashes are one-way. The only attack is guessing inputs, which strong input length defeats.
Why no MD5?
The Web Crypto API deliberately excludes MD5 because it is cryptographically broken; SHA-256 is the recommended replacement.
