I use OpenGPG to sign Git commits on Github and my passwords were expiring too quickly.
I originally tried to increase the key expire times, but this is when the key becomes invalid, not how long the password is cached.
~/.gnupg/gpg.conf doesn’t exist (which is likely), create it.use-agent on it’s own line to the gpg.conf file.default-cache-ttl 86400 to set the password to cache for 1 day.You can list your keys with the following command.
gpg --list-keys
You can set how long a key lasts before it expires with the following command. GPG will prompt you for how long to allow the key to be valid.
gpg --edit-key [key-id] expire
Type quit to exit GPG and select y to save.
