Computes SHA-1/SHA-256/SHA-384/SHA-512 hashes of your text using the browser's built-in Web Crypto API — nothing is uploaded anywhere. MD5 is deliberately not offered: it's cryptographically broken and the Web Crypto API doesn't implement it on purpose.
| Algorithm | Hash |
|---|
Compute SHA-1, SHA-256, SHA-384 and SHA-512 hashes of any text instantly. Useful for checking checksums, generating cache keys, comparing strings without revealing them, or simply learning how hashing works.
Hashes are computed with the Web Crypto API built into your browser — the input is never sent to a server. MD5 is deliberately not offered: it is broken for security purposes and modern tooling should not encourage it.
MD5 has known collision attacks and should not be used for anything security-related. If you need it for a legacy checksum, most operating systems ship an md5 command line tool.
Yes — use the File Checksum Verifier tool, which hashes files locally and compares them to an expected value.
No. Hashing runs in your browser via crypto.subtle.digest().
