In the source code forum, I listed a backup program that I've been using for a number of months. Decided to dust off the source and see what I can do to update it.
My current problem is that the archived files are unencrypted. I've been searching for crypto routines and have narrowed the candidates down to two or three possibilities.
Now here's where I need your thoughts: Should I encrypt the files one at a time as they are backed up, encrypt the entire file in one fell swoop or just shell out to a 3rd party encryption program?
Keep in mind that the file(s) are <= 700 meg big.
Also, along this line, how can my program tell if a file is "in use by another process" so it doesn't crash?
