About Cryptographic Hashes
Hashing transforms any input into a fixed-length fingerprint. SHA-256 and SHA-512 are considered cryptographically secure and are used for file integrity checks, digital signatures, and password storage. MD5 and SHA-1 are fast but broken for security purposes — use them only for checksums.
How to generate file hashes
Switch to the 'File' tab and drop your file into the browser. The tool uses the Web SubtleCrypto API combined with array buffers to stream and hash large files directly from your hard drive without ever uploading a single byte to the internet.
