[feature request] Add an argument to encrypt backups #238

Closed RichyHBM closed 2 years ago

RichyHBM commented 4 years ago

Hello, This request is in some part related to #230 and is a request to add an "--encrypt" argument that would let you encrypt emails on backup. Maybe saving the file as foobar.eml.enc? the argument would then require a "--decrypt" when restoring. Both of these could have a subargument that would be the password.

If not possible, is there any documentation on how GYB knows an email has been backed up locally? If I manyally encrypted the files and appended to the file, would GYB just back up all emails again?

leaving this open to track request and in case I ever find myself with tons of free time but this is unlikely to ever be implemented. The better choice would be to use an existing file / drive encryption solution that allows GYB to backup to a mounted encrypted drive / folder.

It is really simple to use an off-the-shelf encrypted filesystem. I've used GoCryptFS to do this, because it's a good match for GYB: it's reasonably fast, it doesn't add much overhead (some encrypted FS obfuscate the file size by adding padding), it's portable and easy to use (FUSE). I could add a section in the Wiki if you'd like @jay0lee.

I'm just going to go ahead and close this as "will never happen". There are very good per-platform (Windows/Linux/MacOS) tools for encrypting the underlying filesystem GYB is backing up to and I would suggest using those.
