IMPLEMENTATION OF VIGENERE CIPHER WITH EULER KEY GENERATOR TO SECURE TEXT DOCUMENT
Keywords:
cryptography, encrypt, decrypt, Vigenere Cipher, EulerAbstract
There are times when valuable information is very vulnerable to the public. If the information is stored in a text document, in order to prevent information leakage then the text document needs to be secured. Cryptography is a science that studies character encoding, and can be used for securing text documents. In this study, the text document is secured by the vigenere algorithm where the key used is multiplied by the Euler number. The vigenere chiper algorithm with Euleur is implemented in an application built with Visual Studio. This application uses a number of 95 characters from ASCII, starting from number 32 to 126. Encryption and decryption process with vigenere chipper has been successfully done. It is expected that this research can contribute knowledge on how to secure documents.
