How to use
Type or paste text and its MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes appear instantly. Text is hashed as UTF-8 bytes, matching the output of md5sum, sha256sum and most programming languages.
Which algorithm should I use?
Use SHA-256 or SHA-512 for anything security-related. MD5 and SHA-1 are broken for security purposes but still common for checksums and cache keys. None of them is suitable for storing passwords; use a password hashing function such as Argon2 or bcrypt instead.
Is my data safe?
Yes. Hashes are computed in your browser with the Web Crypto API. Your text is never sent to a server.
