PGP Desktop, Keys, and Passphrase Relationship
I would like to know the relationship (how each unit affects the other units) between PGP Desktop, Private Keys, and Passphrase.
I recently changed the Passphrase on my Private key in Administrator User mode. When I switched to Standard User, the new Passphrase did not work. I had to use the old Passphrase, then change it to the new one. In both User modes, I was accessing the same files, and had imported the Key to PGP Desktop from the other User.
This problem also brings up the issue of old (and possibly compromised) Passphrases that are floating around on some backup. Could recently stored files be opened using old Passphrases?
Is there some easy solution, other than finding all my old Keys/Passphrases and deleting them?
