Email has become one of the most important communication methods for any person and organization. However, current industry standards do not emphasize email security. Emails can be intercepted by others easily. Potentially, every not encrypted email sent over a network or stored on an email server can be read, copied, or modified. There is a great need for safe email delivery. Some email service providers, such as Google, took some steps to improve privacy protection based on the https protocol. The main motivation for https is to prevent wiretapping and the attacks of man in the middle. This provides authentication of the Gmail website and the associated web server with which you are communicating, and provides bidirectional encryption of communications between a client computer and the Gmail server. In practice, this is a reasonable guarantee that one is communicating with the Gmail server with which it is destined to communicate, as well as ensuring that the content of the communications between the user and the Gmail server cannot be read or falsified by any third party. However, https only prevents emails from being tracked during network transmission. It does not prevent email server administrators, or anyone else who can access multiple email servers to read email messages, because https is not end to end encryption. The organization on which this work is based, has been in the market for email and SFTP communications for more than 30 years. The thesis identified communication problems by email and other protocols without securing the data sent, as well as who should have access to the data; Furthermore, confidentiality and integrity problems were found in the information sent. Finally, a cryptographic system design is required to provide security for communications and thus have access to information from any place, device, and at any time. The thesis analyzed the options in the market and determined the use of the PGP standard as the most suitable solution for the project.
