Can you explain what is meant by the term PGP in the context of data encryption?

PGP (Pretty Good Privacy) is a data encryption method that ensures the confidentiality and authentication of messages.

Main features of PGP:

• Uses a combination of symmetric and asymmetric encryption.
• A symmetric key is used to encrypt the message, which is then encrypted with the recipient's public key.
• Allows signing messages with a digital signature to verify authenticity.

An example of using PGP is encrypting email so that only the recipient with the corresponding private key can read the message.
