Hash Generator
MD5, SHA-1, SHA-256, and SHA-512 hashes of any text, computed live in your browser using the Web Crypto API. Nothing you type is sent anywhere.
Which one should I use?
Depends on what you're hashing for.
SHA-256 is the safe general-purpose default for checksums and integrity checks. MD5 and SHA-1 are both cryptographically broken (collisions are practical to construct), fine for checking a file didn't get corrupted in transit, not fine for anything security-sensitive like password storage.
Not for passwords
None of these algorithms should be used to store passwords, they're deliberately fast, which is exactly wrong for that job. Password storage needs a slow, purpose-built algorithm like bcrypt, scrypt, or Argon2 instead.
