$ head mykey.ppk PuTTY-User-Key-File-2: ssh-rsa Encryption: none Comment: imported-openssh-key Public-Lines: 6 AAAAB3NzaC1yc2EAAAADAQABAAABAQC8V+PLuklXrfFDZ9GNluXB/L8foOzaEp5s jwaOL1iAxCKDWWsfsmyj9MbhV5r4Z6VGo/0T
Simply pressing enter at the prompt does not work. How can I add this key to the agent?
PS: I've already heard the sermon on security practices, so you can save your breath :-)
