Disadvantage of PGP
- The main drawback of PGP encryption is that it is usually not intuitive to use. PGP requires time and effort to fully encrypt data and files, which might make messaging more difficult for users. If an organisation is thinking about deploying PGP, it has to train its employees.
- It is imperative that users comprehend the intricacies of the PGP system to prevent unintentionally weakening their security measures. This may occur from using PGP incorrectly or from losing or corrupting keys, endangering other users in situations where security is at an extreme.
- Absence of anonymity: PGP encrypts user messages but does not provide users with any anonymity. This makes it possible to identify the source and recipient of emails sent using a PGP solution.
PGP – Authentication and Confidentiality
During 2013, the NSA (United States National Security Agency) scandal was leaked to the public, people started to opt for services that could provide a strong privacy for their data. Among the services people opted for, most particularly for Emails, were different plug-ins and extensions for their browsers. Interestingly, among the various plug-ins and extensions that people started to use, two main programs were solely responsible for the complete email security that the people needed. One was S/MIME which we will see later and the other was PGP.
