RC4 Encryption

Q-Shop implements RC4 (Rivest Cipher 4) encryption for all credit card information stored in the database. This provides an extra level of security to protect your customers data.

RC4 is a stream cipher designed by Rivest for RSA Security. It is a variable key-size stream cipher with byte-oriented operations. The algorithm is based on the use of a random permutation. Analysis shows that the period of the cipher is overwhelmingly likely to be greater than 10100. Eight to sixteen machine operations are required per output byte, and the cipher can be expected to run very quickly in software. Independent analysts have scrutinized the algorithm and it is considered secure.
