Modern life became easier thanks to the contribution of technology, which facilitated access to communication and informational exchange without borders. The digitization of the working processes at the level of public authorities, economic agents, and individuals is directly conditioned by the use of technology, and in this case by electronic signature. Traditional methods of signing and authenticating various documents have been easily replaced by technological innovations aimed at streamlining and facilitating work. In the Republic of Moldova, the legal framework regulates the usage of three types of electronic signatures: simple electronic signature, unqualified advanced electronic signature and, qualified advanced electronic signature. There is an increase in both the number of closed contracts and public-key certificates. The increased security of the electronic signature allows the signed documents to ensure that they can no longer be modified or altered in any way.
