I have just installed gpg4win 3.1.5 and this is my first time working with it. I have created the keypair and exported the public key to an old unix box and have been able to encrypt a file on the unix box and decrypt it on the gpg4win server. I have exported the public key from the unix box and imported it into Kleopatra. But when I right click on a file to encrypt, the key for the unix box is not listed in the “Encrypt for others” box. I type in the email address but there is no drop down to select from, and the icon on the left changes to a white X in a red square. I assume that this means it doesn’t match.
The unix server has GPG 1.4.7. Is there an incompatibility issue? If not, what am I doing wrong?
I have attached a shot showing the new key and imported key in Kleopatra, as well as the encrypt files window showing the lack of a match for the email address.
