Hash Generator

MD5, SHA-1, SHA-256 and SHA-512.

Loading…

A hash is a short fingerprint of data: change one letter and the fingerprint changes completely. Five common algorithms are calculated together as you type.

Open a file to check a download against the checksum its publisher lists. Paste the expected value into the compare box and the tool says whether any of the hashes match.

How to use the Hash Generator tool

  1. Type text, or choose a file to hash.
  2. Paste a known hash into the compare box if you are verifying something.
  3. Copy the hash you need.
  • Verifying a downloaded installer or ISO
  • Checking that two files are identical
  • Generating checksums for your own releases

Tips for the best result

  • Use SHA-256 for integrity checks; MD5 and SHA-1 are only for matching old published values.
  • A hash of a text depends on every space and line break in it.

Frequently asked questions

Can a hash be reversed?

No. It is one-way. Short or common inputs can be guessed by trying candidates, though.

Is MD5 safe?

Not for security. Two different files with the same MD5 can be crafted on purpose.

Should I hash passwords with this?

No. Password storage needs a slow, salted method such as bcrypt or Argon2.

Is my file uploaded?

No. It is read and hashed in the browser.
