Electronic documents (e-documents) are part of public services used to replace paper documents because they have more flexible characteristics, easier searching, save space, digital archiving, easier document transfer, and better security and easy data restoration. In order to maintain and improve data security in a digital document, a mechanism is needed to protect it. The digital signature system is applied to improve the quality of document publishing services. A digital signature on a document means that the signing party has known and approved the document. In today's era when incidents of data destruction and forgery are increasingly common, it has become a necessity to protect any data sent online. For this reason, digital signatures are increasingly popular among professionals thanks to their ability to validate the authenticity of a document, file or software. The method used to create a digital signature in this study is the Ong-Schnorr-Shamir method. The result of this study is a website that is able to produce an formulir digital for a text document. The website also provides facilities to carry out the verification process for the formulir digital to prove the authenticity of the text document in question.
