Hash Generator
SHA-1, SHA-256, SHA-384 and SHA-512 hashes of any text — computed locally, live.

Hashes are computed locally with the Web Crypto API. MD5 is omitted — it is broken and should not be used for anything security-related.
About this tool
Type or paste text and see its SHA-1, SHA-256, SHA-384 and SHA-512 digests update live — for checksums, cache keys, deduplication and verifying downloads against published hashes.
Hashes are computed with the Web Crypto API in your browser, so the input never leaves your device. MD5 is deliberately omitted: it has been cryptographically broken for years.
How to use
- Paste your text.
- Read all four SHA digests instantly.
- Copy the one you need.
Frequently asked questions
SHA-256 is the modern default — fast, widely supported and secure. SHA-1 remains only for legacy comparisons.
MD5 collisions can be manufactured at will, so it is unsafe for anything security-related. Use SHA-256 instead.
No — hashing is one-way. Identical input always gives the identical digest, but the digest cannot be turned back into the input.
