## Frequently asked questions

### Is a password hash reversible?

No. It is used to compare a candidate with a derived value, not recover the original password.

### Decoder or auditor?

A decoder shows JWT structure; an auditor adds security-oriented checks.

### Can a key pair replace a password?

No. Public and private keys support signing or encryption and are different credentials.
