About the Hash Generator
A cryptographic hash function turns any input into a fixed-length string of characters. The same input always produces the same hash, but you can't reverse a hash back into the original data. Hashes are used for verifying file integrity, checksums, and data fingerprinting.
This tool generates SHA-1, SHA-256, SHA-384, and SHA-512 hashes of any text using your browser's built-in Web Crypto API — nothing is uploaded.

Frequently asked questions
Why is MD5 not included?
MD5 is cryptographically broken and unsafe for security purposes, and the browser's Web Crypto API doesn't support it. SHA-256 or higher is recommended.
Can I reverse a hash?
No. Cryptographic hashes are one-way functions by design. The only way to 'reverse' one is to guess inputs and hash them until you find a match.
