Error reading from file

[Craftkiller]

=========Program compiles on both windows and linux===========

Greetings, I am currently working on an encrpytion program that will take a file and a password string and flip the bits based on the pass... ex:

pass: 01
11110000 - file
01010101 - pass (repeated until EOF)
10100101 - resulting file

decryption would be the exact same process, but i've made it slightly more complicated. first at the beginning of the file I have a 4 bit unsigned int that is the size of the file, then a 4 byte unsigned int that is the size of the string of its file name. Then it has the actual string for the file name (the ultimate goal is so that I can have multiple files in there similar to an archive)

The problem is when I try to decrypt my console window spazzes out at me displaying a bunch of random paths like application data and what appears to be an ASCII table...
