Create a hexadecimal checksum from text. SHA-256 is selected by default.

How to generate a hash

  1. Paste the text you want to checksum.
  2. Choose an algorithm. SHA-256 is the usual choice.
  3. Generate the hash and copy the hexadecimal digest.

SHA-1 is included for older checksums. Prefer SHA-256 or stronger for new work. A hash is not a password store and cannot be reversed into the original text.

Frequently asked questions

Which hash should I use?

Use SHA-256 unless a system you are checking specifically asks for SHA-384, SHA-512, or SHA-1.

Is the text uploaded?

No. The digest is calculated in your browser with the Web Crypto API and the text is not sent to our servers.
