SHA-256 hash generator

Create a fingerprint of any text to check it hasn't changed.

Algorithm

How to use the SHA-256 hash generator

  1. Type or paste text.
  2. Choose the algorithm.
  3. Copy the hash.

When it's useful

  • Checking that two texts are identical
  • Generating checksums
  • Learning how hashing works

Limits to know

  • Hashes text as UTF-8. Don't use plain SHA hashes to store passwords — use a password hashing method like bcrypt.

Questions

Can a hash be reversed?

No. SHA hashes are one-way; you can only check by hashing the same text again.
