Proposal for a Way to Counter the Falsification of e-Mails Exchanged using the Outlook E-Mail Client

The purpose of this article is to provide a way to ensure the integrity of e-mail exchanged using the Microsoft Outlook e-mail client. The information exchanged by e-mail, from one correspondent to another in a professional environment or not, is very sensitive to the point that it is necessary to ensure their integrity. Nowadays, one of the most used email clients in the professional world is Outlook which is a product of the Microsoft business. It is technically proven that any message already sent or received using the previously mentioned e-mail client, that is Outlook, can be falsified by both its sender and its recipient. The solution proposed in this article is the use of electronic signatures using digital documents called certificates, obtained through a certification authority. The experimentation of said solution is simulated by means of the virtual machines by considering an illustration made on the basis of the exchanges made between two fictitious users created for demonstration purposes.
