SUPER ENKRIPSI PENGGUNAKAN ALGORITMA CAESAR CIPHER, AFFINE CIPHER DAN RSA UNTUK KEAMANAN DATA

Abstrak

In the ever-evolving digital era, data security has become one of the most important components. With the increasing amount of information technology, safeguarding sensitive information has become a major issue. This is especially true in the fields of communication, banking, and government. Cryptographic techniques are one of the effective ways to maintain data confidentiality. Allowing data to be encrypted, cryptography enables only authorized individuals to access it. This study examines how the combination of three cryptographic algorithms, Caesar Cipher, Affine Cipher, and RSA, results in a super encryption method. Caesar Cipher and Affine Cipher are used for initial encryption, and RSA, which is a modern algorithm with a higher level of security, is used to strengthen the layer of protection. The results of this method show that the combination of the three algorithms can enhance the security of text data by leveraging each of them. It is hoped that this super encryption technique can help address the increasingly complex data security issues in the current digital era.
