Intro to C – Assignment 5 File Encryption The XOR operator is something we had not yet introduced in class. It works on the bits that make up the binary representation of a variable, rather than the value of the variable. For example, each char is 1 byte, or 8 bits. XOR looks at the corresponding bits in each value and creates a new value. If the two bits in the values were different, the output will have a 1 in that position. If the two were the same, the output has a 0 in that position. What makes XOR useful for basic encryption is that the operation is reversible. By using XOR again with the key and the encrypted data, we get the original as output. While this is very easy to implement, keep in mind that this is not very secure.
