Abstract


Information technology developments have positive and negative effects. One of the negative effects is the increase of cybersecurity caseswhich occurfrequently. The information users are not only adults, but also children.Therefore, an application or a cryptography software is required to defence thecybersecurity problem. The significance of cryptography whichwas used in the software was a combination of the twoalgorithms:the Vigenere Cipher and the Triple DES Cipher. The Vigenere Chipher is a classic algorithm which works substitutionally. Beside, the Triple DES Chipher is a modern algorithm; it is created from the Data Encryption Standard algorithm which has been encrypted and decrypted for three times. Thissoftware was designed by using Visual Basic 6.0in order to be able to encrypt and describe a file in txt format. In addition, this software was designed by the user-friendlyinterface which couldsimplifythe use of the software, even for lay users.
