download improvement about cryptmypi

[splitstrikestream]

I like the idea, specially about verifying the hash (in either case).

Some considerations on your suggestion:

1. aria2c does not come installed by default on kali (don't know on other distros), so I think its a good idea to keep the original download method (at least as a backup). The image url could be checked if has a torrent extension or not, so the correct download method could be used.
2. Moving the image (step 2) should be done only after verifying hash.
3. When verifying the hash, if failed it should cleanup as well. no reason to keep bad image
4. Moving should be done to the correct directory at files/images and not to the config. The new default location for images allow sharing between multiple configs.

As you've said, the downloaded torrent contains extra files. This file structure is standarized between distros or each torrent may have the image placed differently?

Greetings,
I think there may be to many specific issues since we are attempting to support various OS like Kali, PiOS, and Debian. Hence with the current download models we hare achieving a common denominator for downloading and verifying. Hence I am going to just mark closed since we have implemented the download hash verification.
