File Share Encryption

Hello Guys,

Our HR and Servicedesk have additional PGP Key pair. The problem is that the signature of those public key expire.

And we can't send encrypted message to them. Uncrypted works fine. Can someone assist me here?

With what key mode are the keys created?  Depending on the key mode, you might just be able to synchronize the keys with the server to get the signature renewed.  You can manually force the Organization key to renew signatures of all keys on the server by starting an SSH session and issuing the following command:
pgpkeymaint --update-sigs

More info on setting up SSH here if you need it:

Since it is just an expired signature, you should be able to get that signature renewed, and not have to generate a new keypair.

Hello Mike,

Thank you for replying to my question. We are using GKM Key mode for our PGP Server. I will try your solution and inform you about the result.
