Analisa dan Implementasi Kriptografi File Dokumen Dengan Metode Algoritma Advanced Encryption Standard (AES) Berbasis Web

Abstract

Security and confidentiality when exchanging data and information are very important in the current era of information and communication technology, therefore a branch of science has been developed that studies ways to secure data or known as cryptography. There are quite a number of algorithmic methods in cryptography, one of which is the Advanced Encryption Standard (AES) algorithm, which is a cryptographic algorithm that can be used to secure data. With the implementation of a cryptographic system so as to reduce the possibility of a data security crime risk because messages or files and documents are protected. The results obtained from this study are the implementation of a document file cryptography system using the Advanced Encryption Standard (AES) algorithm method and then processed, so that the system can perform encryption and decryption.
