Cryptography is knowledge of encoding messages by observe to security
aspects. Cryptography uses two types of keys, namely symmetric keys and
asymmetric keys. Vigenere cipher is a technique to encrypt messages by symmetric
key. Vigenere cipher can be combined by several patterns and ASCII code. The
pattern used can vary as long as the text can be returned to original message (can be
decrypted). On this paper, we will modified plaintext before encrypt using vigenere
cipher. The way to modified the plaintext are flip and shift rows of bit. The effect of
the algorithm changes can be seen based on the renewal value obtained. If the
correlation value gets smaller, it means the algorithm is better. The results of this
study is the correlation value using vigenere cipher with modified plaintext is better
compared to vigenere cipher with original plaintext.
