Use it to verify a downloaded file or string has not changed, or to compare values without exposing them.
Examples
- Compare the SHA-256 of a downloaded ISO against the publisher's checksum.
- Generate a SHA-512 to confirm two configuration snippets are identical.
Common mistakes
- Using plain SHA hashes to store passwords; use bcrypt or Argon2 instead.
- Comparing hashes of text that differs only in trailing newlines or spaces.
