Hash Generator
Generate MD5, SHA-1, SHA-256, and SHA-512 hashes online. Secure hash calculator for passwords, files, and data verification.
Calculate five checksums for text or a local file, compare a digest and export hashes.txt.
Hashing is not encryption or password storage. MD5 and SHA-1 are weak against collisions. Files up to 500 MiB are read into memory; browser limits may be lower. Text cap: 1,000,000 characters; file cap: 500 MiB.
Method and limits
Method and limits
MD5 uses the local implementation; SHA-1, SHA-256, SHA-384 and SHA-512 use WebCrypto. Progress counts completed algorithms, not file-read bytes.
