Hash generator

Get MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes of text or files, make HMACs, and compare checksums.

How to use the hash generator

  1. Type text or choose a file.
  2. All hashes appear at once. Switch between hex and Base64 if needed.
  3. Paste an expected checksum under Compare to verify a download.

Frequently asked questions

Is my file uploaded?

No. The file is read and hashed in your browser, so it can be private or very large without being sent anywhere.

Which hash should I use?

SHA-256 for most purposes. MD5 and SHA-1 are fine for checking downloads but are not secure against deliberate tampering.

What is HMAC?

A hash mixed with a secret key, used to sign messages and API requests. Enter a key to get HMAC-SHA results.
