Abstract

Data security in sending files needs to be a priority, especially for files sent that are confidential files; so we need a way to secure the data in the form of the file. Various methods and algorithms that can be used include the CAST-128 and RSA algorithms; where in the CAST-128 algorithm is a cryptographic algorithm using 16 feistel rounds which is one of its superior features which also in CAST-128 uses blocks of 64 bits long and a usable key length of 128 bits. Meanwhile, RSA is an easier algorithm to implement which can be used to support the CAST-128 algorithm in strengthening cryptographic algorithms to secure data in files. So that with the combination of the CAST-128 and RSA cryptographic algorithms, it is hoped that it can help improve data security in files that can be in the form of image, sound, video or file formats in other formats to avoid theft and theft of files sent via computer networks.
