Cryptology is a science that deals with codes and passwords. Cryptology is alienated into cryptography and cryptanalysis. The Cryptography produces methods to protect the data, and cryptanalysis hack the protected data . Cryptography provide solutions for four different security areas - confidentiality, authentication, integrity and control of interaction between different parties involved in data exchange finally which leads to the security of information .Encryption algorithms play a key role in information security systems. This paper provides critical analysis of six most common encryption algorithms namely: DES, 3DES, RC2, Blowfish, AES (Rijndael), and RC6. A comparative study has been carried out for the above six encryption algorithms in terms of encryption key size ,block size, Number of Rounds ,Encryption/decryption time ,CPU process time, CPU clock cycles (in the form of throughput), Power consumption. And these comparisons are used to conclude the best Symmetric Cryptography Encryption algorithm.
