How it works

  1. Input text is converted to UTF-8 bytes.
  2. The browser Web Crypto API computes the selected SHA digest.
  3. The digest is shown in hex and Base64 encodings.

Limitations

  • This scaffold hashes text, not uploaded files.
  • SHA hashes are not password storage by themselves; use a password hashing algorithm for credentials.

FAQ

Which hash algorithms are available?

The current tool supports SHA-256, SHA-384, and SHA-512 through Web Crypto.

Is this suitable for passwords?

No. Passwords need dedicated slow password hashing such as Argon2, bcrypt, or scrypt.
