program kriptografi caesar cipher dengan java

From the test results obtained ciphertext that can be read. However, there are some alphabet consonants are not replaced, this is because the frequency of the alphabet is rarely used in an Indonesian text.

Caesar cipher modification is done by replacing the alphabet into two parts, the vocals were replaced with the alphabet vocal too, and the consonant alphabet was replaced with a consonantal alphabet. With the ciphertext that can be read, then cryptanalysis not suspicious of the ciphertext. In this paper, the authors modify the Caesar cipher method that produces ciphertext that can be read. While the use of steganography owner of the information is difficult to determine the method or pattern to be formed in composing the message that will be hidden. Thus, the cryptanalyst attempts to break the encrypted message. This is possible because usually a text message unreadable gives someone suspicion that the text message contains a certain meaning for the owner of the message.

On the other side, it turns out the use of cryptography can often be solved / translated by another person or cryptanalyst. However, both methods have the same goal, namely the attempt to conceal the message. In a secret message, cryptography is more directed to the encrypted message while steganography is more directed at the hidden message.
