Abstract

Digital signature is an authentication mechanism that allows the message maker to add a code that can act as a signature. The value of a digital signature is highly dependent on the original document and the message maker, so it will have a unique value for each existing signature. In this research, software development is carried out to test the integrity of documents with digital signatures built using the MD5 hash function and the RSA algorithm which is then generated into a Qr-Code on a document consisting of 1000 words with the .docx extention. The document to be tested is given a digital signature with the software built and then integrity testing is carried out by modifying the text file. This research also calculates the processing time by the system using 10 documents, with 8 bit and 13 bit key-forming values during encryption and the validation process of signed documents. The average time required for the encryption process will be longer when a high key-forming value is used. However, in the decryption process, the processing time between the high and low key-forming values did not have a significant difference. In this research, software has been created to apply the authentication scheme to a document. From the results of the research, it can be concluded that the MD5 hash function and the RSA algorithm which is generated into a Qr-Code can be implemented to be used as digital signatures. In addition, a large key-forming value will affect to the signing process.
