Abstract
Along with the computer and the communication rapid development, the cryptology already seeped domain and so on politics, economy, culture and even inspanidual privacy, the use encryption technology protects the information the security to change more and more importantly. This paper key point is introduced several classical passwords systems, the classical password encryption decipher demonstration and its uses C++ the realization. This paper through the encryption algorithm has provided some useful references to the cryptographic system comparison as well as to the encryption algorithm utilization for the cryptology in the daily life utilization scope and its using the method.
