Hash & Checksum Generator

Computes the SHA-256, SHA-384, or SHA-512 hash of a text or a local file using crypto.subtle.digest(), with the result in HEX and Base64, a secure comparison against an expected hash, and SHA-1 available only as a compatibility option with a visible warning. The file is never uploaded to any server; a simple hash is no substitute for a specialized password-storage algorithm.

How to use this tool

  1. Choose text or file and the algorithm
  2. Compute the hash and copy it in HEX or Base64
  3. Optionally compare it against an expected hash

Frequently asked questions

Can I use this tool to store user passwords?
No. A simple hash (SHA-256 or similar) is no substitute for a specialized password-storage algorithm (like bcrypt or Argon2), which add salt and deliberate computational cost.
Why does it include SHA-1 if it isn't secure?
Only as a compatibility option for legacy systems that still require it, with a visible warning that it shouldn't be used in new applications.
