SECURING DIGITAL SIGNATURE DATA USING THE RSA AND HASH ALGORITHM METHODS

Abstract

This research aims to maintain the authenticity of the message to be sent to provide assurance to the recipient that the message is free from changes or modifications made by other parties. If there is a change to the message, the recipient will know that the original message is no longer maintained, so that the recipient of the message avoids using the wrong data. To maintain data authenticity, digital signature techniques are used using the RSA algorithm as a public key algorithm and a hash function to produce a message digest of the messages sent. The combination of the two algorithms will produce a digital signature for each file or document that can be maintained as authentic.Keywords : Digital Signature, RSA Algorithm, Message Digest, Hash Function.
