How does PGP email encryption work and why is it needed?
Email is a protocol that transmits messages in plaintext by default. Any message along the path from the sender to the recipient can be read by telecom providers, mail server owners, or intercepted by attackers. PGP, or Pretty Good Privacy, solves this problem by providing end-to-end encryption for text messages.
The system is built on using a key pair: public and private. You can freely distribute your public key among your contacts so they can encrypt messages for you. The private key is stored strictly and securely only on your device and is used to decrypt received mail.
The process of implementing and using PGP consists of the following stages:
Using PGP guarantees that even in the event of a mail server breach or traffic interception by a provider, the content of the correspondence remains inaccessible to outsiders, protecting your privacy.
