PGP stands for Pretty Good Privacy. It's an encryption program used for securing and encrypting electronic communications, such as emails, files, or messages. PGP uses a combination of symmetric-key and public-key cryptography to ensure confidentiality, integrity, and authentication of data.
With PGP, users can generate a pair of cryptographic keys: a public key and a private key. The public key is shared openly and used by others to encrypt messages that only the holder of the corresponding private key can decrypt. This system enables secure communication between parties without the risk of unauthorized access to the encrypted content. PGP is commonly used for secure email communication and data encryption in various fields, including business, government, and personal communication.
