How to use Hash Generator

  2. All five digests are calculated at once as you type.

  3. Copy a hash, or paste a reference value to check whether it matches.

Frequently Asked Questions

Can a hash be reversed?

No. Hashing is one-way. Short or common inputs can still be found by brute force, which is why MD5 and SHA-1 must never be used to store passwords.

Which algorithm should I use?

SHA-256 for anything security related. MD5 remains useful only as a fast checksum when you are comparing a file against a published value.

Is my file uploaded to hash it?

No. The digest is computed in your browser with the Web Crypto API, so even a large file never leaves your device.
