Bash based cryptolocker
I wrote this in a hack/prep night to for the information security talent search (ISTS) @ Rochester Institute of Technology.
Please improve/learn from this, its academic code and in no way do I endorse using this for evil.

Things to note:
I have a white_list to make sure you dont encrypt everything, it encrypts everything in the target directory. You can instead substitute this for a file extension list and only encrypt those extensions and filter through sed
./lol.sh password targetdir
./dec.sh password iv targetdir
Ideally, port a pub key to encrypt the symmetric key:IV to send that as one parameter when you encrypt everything.
Also, separate IV per file, and better encrypted file detection (magic values prepended/appended instead of an extension is ideal)
