Abstract

Digitalization of files provides many advantages, especially for companies or organizations, but there are things that hinder the process of digitizing files, namely doubts about the originality of digital files because digital files are easy to manipulate. Digital signatures can be a solution to doubts about the originality of digital files. Digital signatures use hashing algorithms and cryptographic algorithms with two actors, one as the sender (signer) and the other as the receiver. This study is to determine whether the MD5 as a hashing algorithm and the Modified ElGamal Cryptosystem as a cryptographic algorithm can maintain the originality of digital files with many signatories. Tests were carried out on digital files with the extentions pdf, docx, and xlsx with the number of signers 10, 11, 20, 21, 30, 31, 40, 41, 50, 51, 99 and 100. Based on the results of tests performed showed 100% MD5 and Modified ElGamal Cryptosystem can recognize the original and modified files, so that the MD5 and Modified ElGamal Cryptosystem algorithm can maintain the originality of digital files.
