Description Author

This class can encrypt and decrypt data using the XOR (exclusive OR) binary operation.

An encryption password text is combined with the data being encrypted and a random input vector using the XOR binary operation. The encrypted result is return encoded with the base64 algorithm.

The class can also decrypt data using the same encryption password by applying the reverse algorithm.
