RSA Algorithm Measurement Levels in Ms.Word Security

Abstract

With the rapid rise of information technology in Indonesia, the risks associated with it, such as the leakage or theft of sensitive data, are increasingly apparent. Among the most frequently shared file formats, Microsoft Word documents are a crucial factor. Therefore, this study aims to implement and evaluate the performance of the RSA cryptographic algorithm to protect these types of documents. The applied methodology includes the design and implementation of a system using PHP, a data farm using MySQL, and an Xampp-based test environment. We utilized RSA to encrypt and, conversely, decrypt the Word files, with the main indicator being the processing time for each type of process. Theoretical analysis and manual calculations confirmed that RSA operates through the risk inherent in the difficulty of factoring large prime numbers. Manual simulations of encryption and decryption times verified that the RSA algorithm, when inverted, produces data in the correct format. Based on the results obtained, we conclude that the use of RSA in securing Word is feasible and appropriate, and the degree of protection can now be evaluated through the time required for each encryption and decryption operation.
