Pgp (pretty good privacy) is a public key encryption program that has become the most popular standard for email encryption (the. Asymmetric algorithms, such as public/private key cryptography use one key for encryption and a different, though mathematically related key for decryption. Public-key cryptography and related standards and techniques underlie the security features of many products such as signed and encrypted email, single sign-on, and. Asymmetric keys, also known as public/private key pairs, are used for asymmetric encryption asymmetric encryption is used mainly to encrypt and decrypt session keys. In such a cryptosystem, the encryption key is public and it is different from the decryption key which is kept secret (private) in rsa. Public-key cryptography: public-key cryptography, asymmetric form of cryptography in which the transmitter of a message and its recipient use different keys (codes.
