When entering the wrong password, fernet throws an 'InvalidToken'
exception. This is now handled, but does not fully shutdown pappy.
Working on asking for password multiple times, then shutting down
completely after reasonable amount of total tries, e.g. 3.
Crypto mode for pappy now works. Still need to work out the kinks
for not supplying a project file to `pappy -c`, but when supplied
encryption and decryption work.
Project is now properly encrypting the archive,
and now I just need to ensure proper decryption
is happening. Also need to work on cleaning up
clear text versions of the crypt project files.
Need to write tests for flushing out edge cases.
In the function for grabbing project files (`Config.get_project_files`)
I was overcomplicating getting the current working directory.
Simplified the process and removed the bug!
Attempting to get stub file creation and copying working. Fixed
syntax errors, and now attempting to get password reading working
in the test environment.
Converted the crypto and compression plugins to core features, and
added the utility variables and functions to the Config class in
``config.py``. Added helper functions in PappySession class in
``pappy.py`` to enable the user to pass in an encrypted project archive.
Next moving to testing and debugging!
Cleaned up the huge mess I created, pushing back to catch everything up.
Redoing crypto plugin as main component instead of plugin.
Likely compressing existing project files on first crypto run,
then storing the encrypted archive blob in the project directory.
When pappy started again, it will see the encrypted blob, extract
files to working directory, do all of its work in that directory,
then exit the directory, and clean up all files. A lot of work, but
worth the end result!
For more details on what affects you, look at the README
diff. Most of this was reworking the internals and there were so many
changes that I can't really list them all.
