I'd like an application that supports encrypting/decrypting files using gnupg keys. Actually, what I'd really like is password-store (aka pass) running on Sailfish, but the first option would be a reasonable workaround, for now. Once my current work project ends and I get some free time, I may look into porting pass, but just don't have time at the moment. There are Android apps that will do it (there's an Android version of password-store on FDroid) but there's an issue in the AlienDalvik which means that it and none of the keychain apps can import a key from a file (they can only see image files). That said, I'd prefer it to be native anyway, for no necessarily logical reason.
