Pure Ruby implementation of the general encryption algorithm
Since this algorithm is implemented in pure Ruby, it is not very fast. Therefore the
FastARC4 class based on OpenSSL should be used when possible.
For reference: This implementation is about 250 times slower than the

Processes the given data.
Since this is a symmetric algorithm, the same method can be used for encryption and decryption.
