Abstract:Confidentiality of data is a very important thing . It aims to prevent the data can not be read and used by unauthorized people and people who are not interested , such as data theft or receiving erroneous data due to shipper error . To overcome the problem of the developed technique known as cryptographic security . The reasons that drive interest to conduct this research . There are many types of cryptographic algorithms and is generally categorized into two groups: block ciphers and stream ciphers . This research will be conducted comparing two cryptographic algorithms , namely Sapphire II and RC4 . In principle, the algorithms are different but still belong to the stream cipher . To the researchers examined the performance of both methods in terms of avalanche effects and the computational time required to encrypt and decrypt a file . The key used by the RC4 algorithm and Sapphire II is of 256 bits . The software is designed based under windows using Visual Basic programming language . The software is designed to encrypt binary files ( * . * ) Because the file is done reading mode binary files include text , audio , image , and video . Comparisons are made ​​in terms of the speed of encryption / decryption process , Avalanche Effects , and character distribution ( distribution of bytes ) .
