Data confidentiality is an important aspect of information systems. In case of that we need an application to maintain data confidentiality. This study aims to compare two methods of data security systems, namely using the RC4A algorithm which is a symmetric key cryptographic algorithm and the RSA algorithm which is an asymmetric algorithm with a hybrid process on the RC4A and RSA algorithms to secure the secret key of RC4A and speed up the encryption process of RSA. The study uses a comparative test on two algorithm methods, according to data security system parameters. Data is encrypted with the RC4A algorithm and the RC4A key obtained from KSA RC4A will be encrypted with RSA before sending to the receiver. The test results get Hybrid cryptosystem RC4A-RSA faster in completing the encryption process than RSA. Furthermore, the RC4A key can be secured by being encrypted using the RSA algorithm.
