Passwords need slow hashes
SHA-256 is fast and inappropriate for password storage alone. Prefer bcrypt, scrypt, or Argon2 from dedicated tools when storing credentials.
Common Use Cases
- Verify downloads against published checksums
- Fingerprint config files in support tickets
- Teach integrity concepts before introducing HMAC
- Compare outputs with MD5 when legacy systems require migration planning

Frequently Asked Questions
- Is SHA-256 the same as encryption?
- No. Hashing produces a fixed-length digest you cannot decrypt back to the original. Encryption is reversible with the correct key.
- Hex vs Base64 output?
- Same bits, different encoding. APIs may expect lowercase hex while others expect Base64—match your verifier’s format.
