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.

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.
