Encrypt and decrypt a file using GPG through the fman plugin api
Note This is my first plugin for fman (https://fman.io) - please let me know if you have issues.
This plugin assumes that you have a working installation of GPG and have set up a keyring. I am not providing any guidance on that, as there are many tutorials available online.
For convenience I am providing a copy of gnugp.py pulled from the tarball available at https://pypi.org/project/python-gnupg/#files. I have also included here a copy of LICENSE.txt for gnupg.py from that tarball as well.
These commands assume the default for gnupghome. If this is not the case for you, you may have to provide this in the initialization: gpg = GPG().
- These commands assumes that only one file in the active directory is selected. I may provide a check on this in future versions (should be easy), or iterate through multiple selections (a little harder), but this first round assumes you have just the one file selected.
- I know there may be a use case for selecting a directory and recursing through each file within it, but I don't have need for such a feature (yet).
The first run of the Gpg Encrypt will prompt for a default recipient. This recipient should (obviously) be in your keyring. I don't do any checks on the availabity of the key. From then on, it will still prompt you for the recipient, but this will be pre-populated with the default.
-
GPG EncryptWith one file selected, it will prompt for the recipient, and will encrypt to "filename.ext".gpg - if the gpg file exists, it will be overwritten. (You have been warned!) -
GPG Decryptwill reverse the process. Selected a GPG-encrypted file. The command will always prompt for the passprase. I'm sorry this is clear text in the window - I don't know how to mask it, but it is not stored. A default filename is provided (the same as the input without the.gpgextension) for you to edit or accept as is.
Both commands give you the status message returned by gnupg encrypt or decrypt.
