Cryptographic algorithms provide security against attacks during encryption of data. However, they are computationally intensive application and consume large amount of CPU time and space at time of encryption. This paper is to compare the different encryption algorithm and to find space complexity of the encrypted and decrypted data by using complexities of encryption algorithm. In this paper, provide comparison between five most widely used algorithms. Based on following experimental it can be seen that TDES in general perform better than other algorithms.
