Create MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes of any text.
Hashes
These are the hashes of empty text. MD5 and SHA-1 are fine for checksums but shouldn't be used to protect passwords.
Last reviewed by the OnlineToolPro team
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.

Good to know
SHA-256 is the everyday choice for checksums, signatures and data integrity. SHA-384 and SHA-512 give longer outputs. MD5 and SHA-1 are broken for security purposes but still common for quick checksums and legacy systems.
Many downloads publish a SHA-256 checksum. If the hash of the text you have matches the published one exactly, the content is identical — one changed character gives a completely different hash.
FAQ
No — hashing is one-way. Sites that “decrypt” MD5 just look it up in lists of common inputs.
No. Use a dedicated password-hashing method such as bcrypt or Argon2 on your server.
Usually hidden differences: a trailing space, a line break at the end, or different letter case. Hashes change completely with any difference.
