Hash & Crypto
Hashes are everywhere: file checksums, data integrity checks, string fingerprints, password storage. Here you can instantly compute MD5, SHA-1, SHA-256 and CRC32 for any string, compare two hashes and generate a cryptographically strong password of the desired length. All computations run through the Web Crypto API locally — the source text is never uploaded.
