Practical guidance
Separate signing and encryption keys when your process calls for it. Set an expiry date and keep a revocation certificate. Verify fingerprints through an independent channel before exchanging confidential data.
Before using this tool
Define what you need from GPG key generator and prepare the relevant input. When diagnosing a live service, record the test time and connection conditions so you can compare results after configuration changes. Check findings against the documentation for your software.
