That session key is included in the message in encrypted form and was itself decrypted using the recipient's private key. The recipient of a PGP encrypted email message decrypts it using the session key for a symmetric algorithm. Many PGP users' public keys are available to all from the many PGP key servers around the world which act as mirror sites for each other. That key is used, finally, to encrypt the plaintext of a message. a secret key or conventional key) for a symmetric cipher algorithm. The sender uses the recipient's public key to encrypt a shared key (a.k.a. PGP message encryption uses asymmetric key encryption algorithms that use the public portion of a recipient's linked key pair, a public key, and a private key. PGP encryption uses public-key cryptography and includes a system which binds the public keys to user identities. The OpenPGP standard was originally derived from PGP. PGP is similar to PKI (Public Key Infrastructure) and is based on asymmetric (open-key) cryptography. Pretty Good Privacy (PGP) is a strong encryption program used to encrypt files and e-mail.
