About this hash generator
A hash is a fixed-length fingerprint of some data. The same input always gives the same hash, and changing a single character changes the output completely.
Hashes are used for checksums, deduplication and integrity checks. Note that SHA-1 is considered broken for security purposes and is included only for legacy comparison.
How to use it
- Type or paste your text.
- The hashes for each algorithm are calculated as you type.
- Copy the one you need.
Hash Generator — FAQ
Can I reverse a hash?
No. Hashing is one way by design. Short or common inputs can be found by brute force, which is why passwords need salting and a slow algorithm.
Should I use SHA-256 or SHA-512?
SHA-256 is the sensible default. SHA-512 is not meaningfully more secure for most uses, though it is faster on 64-bit hardware.
Is MD5 supported?
No. MD5 is thoroughly broken and the browser's crypto API does not offer it.
