TIP: For more information about public-key cryptography, refer to a great historical PGP document 'Intro to Crypto' document provided at the bottom of this article as an attachment. When data is encrypted with a public key, it is common to say that the data was encrypted 'to' the public key. Thus when you want to send someone encrypted data, you use their public key to encrypt the data, which may then only be decrypted by their private key. Once the data is encrypted with your public key, it may only be decrypted by your private key, for which only you know the passphrase. When someone wishes to send you encrypted data they use your public key to encrypt the data, which changes the data into encrypted content so only the intended recipients can decrypt. Your private key, however, should never be given to others, and its passphrase should be kept totally secret. Your public key should be given to anyone who wishes to send you encrypted data. In order to use PGP you must create a PGP keypair, which consists of a public key and a private key. PGP encryption (Symantec Encryption Desktop) is based on public-key cryptography.
