Cryptographic hash functions produce a fixed-size digest from arbitrary input. They are one-way functions used for data integrity verification, password storage, and digital signatures.
All hashing is performed locally in your browser using the Web Crypto API. Your data never leaves your device.
The Web Crypto API doesn't support MD5 natively. We provide SHA-1, SHA-256, SHA-384, and SHA-512.
