Hashes

MD5
SHA-1
SHA-256
SHA-384
SHA-512

These are the hashes of empty text. MD5 and SHA-1 are fine for checksums but shouldn't be used to protect passwords.

What is the Hash Generator?

A hash is a short fingerprint of some text: the same input always gives the same hash, and any change gives a completely different one. Generate MD5, SHA-1 and the SHA-2 family at once.

How it works

How to use the Hash Generator

3 simple steps. No experience needed.

What can you use it for?

  • Check that two pieces of text are identical.
  • Create a checksum for a value in a script or config.
  • Compare a hash from documentation with your own.

FAQ

Frequently asked questions

Can a hash be decrypted?

No — hashing is one-way. Sites that “decrypt” MD5 just look it up in lists of common inputs.

Should I use MD5 for passwords?

No. Use a dedicated password-hashing method such as bcrypt or Argon2 on your server.
