Security is a practice of defending our computers, servers, networks, mobile devices, electronic systems, and digital information against accidental and malicious attacks in the field of Information Technology. One way to protect such valuable information is to use cryptography. Cryptography or encryption algorithm is the process of transforming sensitive data into confounding data in such a way that the person or the machine with a key can decode the hidden information. In this article, a hybrid approach of the Vigenere cryptosystem was used in encrypting and decrypting the data. This approach will be integrated with the learning management system using matrix manipulation and the Base94 encoding scheme. The experimental result of the study shows a significant high avalanche effect compared to the original Vigenere cryptosystem.
