Must take in a bitmap file, and will save as a bmp.

Encryption done by offset, actaul offset is the specified number squared.

Encryption works as follows

123

456

789

with an offset of 2 this becomes

1002003

0000000

0000000

4005006

0000000

0000000

7008009

and then is translated such that each zero is a random pixel from the original image. This will then be done again with the new image.
