+Beginning with Secretive 2.2, every secret has an automatically generated public key file representation on disk, and the path to it is listed under "Public Key Path" in Secretive.

+
+Yes, you can! Once you've set up Secretive, just add `ForwardAgent yes` to the hosts you want to forward to in your SSH config file. Afterwards, any use of one of your SSH keys on the remote host must be authenticated through Secretive.
