Generate MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes from text or files. Instant, client-side, private.
Start typing to see hashes
One-way
A hash cannot be reversed. You can't get the original text back from its hash.
Deterministic
The same input always produces the same hash. Even one character change gives a completely different result.
File integrity
Compare hashes to verify a file hasn't been tampered with or corrupted during transfer.
