# 1. Add a key profile
                    $ crypto add production -k "mySecretKey12345!"
                    ✓ Profile 'production' saved.

                    # 2. Encrypt a connection string
                    $ crypto encrypt "Server=db.prod;Password=s3cret" -n production
                    ┌──────────── Encrypted ────────────┐
                    │ dG9wIHNlY3JldCBiYXNlNjQgb3V0... │
                    └───────────────────────────────────┘

                    # 3. Decrypt it back
                    $ crypto decrypt "dG9wIHNlY3JldCBiYXNlNjQgb3V0..."
                    ┌──────────── Decrypted ────────────┐
                    │ Server=db.prod;Password=s3cret │
