An effective cryptographic algorithm plays a major role in secure communications which is important for today's digital world. Network security primarily depends upon Cryptographic algorithms as its applications are. The main goal of a cryptographic algorithm is to satisfy four conditions which are Integrity, Confidentiality, Authentication and Nonrepudiation. Though there are numerous algorithms there is a chance of drudge caused due to adversaries and hence for the better security we in this paper considered few existing algorithms and on few modification we compared them through their performance level on considering few factors like encryption time, throughput, computational time and memory usage. We also added a new concept related to steganography in this paper where that technique is evaluated based on histogram level. The proposed algorithm is effective for secure communications in this digital era. In this study is made particularly for the evaluation of comparison and performances of cryptographic algorithms. © 2006-2017 Asian Research Publishing Network (ARPN).
