I'd been looking for a fairly secure way to store an increasing number of passwords. There's a large number of methods one can use. While the most secure might be an encrypted file on a system that has no network access, I do want to have access to the information over a network while I'm traveling. Remote access makes using a graphical client a poor choice.
After a moderate search and trying a number of candidates, I settled on Console Password Manger (CPM) written by Harry Brueckner. It's close to an ideal match to my needs: it's console-based, had an emphasis on security and uses my existing GPG key for encryption. The program is maintained and I've had no issues while using the last three beta versions of the program. Thanks, Harry for the very good tool. Recommended.
