Hash Generator
Get the MD5, SHA-1 or SHA-256 hash of any text.
Questions
Which hash should I use?
SHA-256 for checksums, signatures and anything security-related. MD5 and SHA-1 are broken for security (people can craft two inputs with the same hash) but are still used to match older checksums and cache keys.
Why doesn’t my hash match another tool’s?
Usually because of an invisible difference: a trailing space or line break, Windows line endings, or a different text encoding. This tool hashes exactly what is in the box, as UTF-8. Many command-line tools add a line break at the end; turn on “Add a line break” to match them.
Can a hash be reversed to get the text back?
No. A hash is one-way. Short or common inputs can still be found by guessing and comparing, so don’t treat the hash of a password as a secret.
How do I hash a file?
Use the file hash calculator, which handles files of any size.
Is it free? Do I need an account?
It is free to use and there is nothing to sign up for. There are no watermarks and no daily limits.
