Generally, encryption it’s an encoding information process in order to provided security against unauthorized access. Nowadays, there are different types of cryptographic methods to provide high security level. Basically, each of cryptographic algorithms has its own weak and strong points. In this paper, presented the result of implementation and analysis that applied on several cryptographic algorithms such as Twofish, Blowfish, RSA and new hybrid model of those algorithms. The paper presents comparison of two symmetric key algorithms and their hybrid implementation in terms of performances, weaknesses and strengths. Proposed experimental research results on Blowfish and Twofish algorithms shows their advantages, disadvantages and strength against cryptanalysis. JAVA programming language was used to analyze those decryption algorithms.
