Overview

Computes common cryptographic hash digests of text — useful for checksums, cache keys and verifying data integrity.

How to use it

1Type or paste text.
2MD5, SHA-1, SHA-256 and SHA-512 digests are computed and shown together.
3Click any digest to copy it.

How it works

SHA-1/256/512 use the browser's native Web Crypto API (crypto.subtle.digest). MD5 is not exposed by Web Crypto (it's considered broken for security use) so it's computed with a small local implementation — MD5 is included here for legacy checksum compatibility only.

Tips

MD5 and SHA-1 are broken for security purposes (collisions are practical to generate) — use SHA-256 or SHA-512 for anything security-sensitive.
