        Abstract: After mastery these types of algorithms, compared the advantages and disadvantages between the Symmetrical cryptograph and nonsymmetrical cryptograph, as well as consider the two demands in front, at last decide use DES algorithm and the RSA algorithm to design and realize my encryption system. In this article, Detail the theoretical principles of Cryptographic and note the detailed of design and realize process..
