Abstract

The Rapid advancement of technology has led to crimes committed using information technology, one of which is digital document forgery. This has resulted in issues concerning the misuse of such digital documents by irresponsible individuals. To maintain the authenticity of distributed messages, a method is required to serve as an assurance that the documents are not manipulated. Digital signatures are one of the methods that can be used to ensure the authenticity of distributed messages. This research utilizes the SHA-256 and RSA algorithms in its implementation. The data used in this study is obtained from the website https://repository.unsri.ac.id/. The testing of the avalanche effect on modified documents concludes that encryption in digital signatures does not affect the value of the avalanche effect. Furthermore, the testing of the values P and Q used to form key pairs in the RSA algorithm demonstrates that these values affect the duration of the encryption process in digital signatures.
