3. August 2024 in Administration, GNU/Linux, Programmierung.
GnuPG is a powerful cryptographic tool that enjoys widespread support by F/LOSS mail user agents. However, due to a lack of conventional public key management it is plagued by key-related issues. One such issue is the expiry of GnuPG keys, which often goes unnoticed by affected messaging partners until such time when it actually disturbs […]
