In this paper we firstly discuss the general concepts of compter security and cryptology, and then describe the mostly used modern encryption methods and technologies. We detail the advantages and disadvantages of symmetric algorithm, public-key algorithm and one-way hash function. At last we put forward a new block cipher - permutation code, and describe the secret hash digital signature and online electronic contracting with the trusted third party system.
