Formula

hash = SHA(UTF-8 bytes of the text), written as hexadecimal

How the hash generator works

  1. Step oneType or paste the text.
  2. Step twoThe four hashes appear below and change as you type.
  3. Step threeCopy the one you need. The same text always gives the same hash.

What this tool does not do

  • A hash cannot be turned back into the text, and this tool does not try to.
  • It is not a password hashing method: for storing passwords a slow, salted method is needed.
  • SHA-1 is shown for checking old data only; it is not safe against deliberate collisions.

Frequently asked questions

Is a hash the same as encryption?

No. A hash is a one-way fingerprint. You cannot get the text back from it, and a tiny change in the text gives a completely different hash.

Which hash should I use?

SHA-256 is a good default. SHA-1 is no longer considered safe against deliberate collisions and is shown only for checking old values.

Why is MD5 missing?

This page uses the hashing built into your browser, which does not include MD5. The MD5 generator on this site has its own MD5 code.
