摘要：Cryptography is concerned with keeping communications private. Today's cryptography is more than secret writing. The purpose of this paper is the implementation of three encryption algorithms and a comparison between them based on CPU execution time, System time and User time. In bibliography, there are three encryption algorithms RSA, DES and BLOWFISH using two separate modules of encryption and decryption. The objective of this paper is to evaluate the performance of the three cryptography algorithms in terms of the processing time required in the kernel and user space for encryption and decryption operations. The powerful portable programming language Java and JCA (Java Cryptography Architecture) is used in implementing the encryption algorithms. The performance of the implemented encryption algorithms will be evaluated on Windows platforms
