be a fantastic combination for portable encryption/signing. Of course I understand context menu options (such as right clicking on a file) couldn't list the encryption option because it would require an install but even without it's still cool. Maybe a .reg file could also be included so if people wanted/were able to they could get the menus in explorer. At the moment I'm using the non-portable version and it's a pain in the ass when it needs updating etc. Portable app is easy, delete the old and put the new, first of all saving preferences.
