Encryption PGP (Pretty Good Privacy)

BASIC THEORY



" PGP" (Pretty Good Privacy) is a type of encryption used for encrypting email. created by Phil Zimmerman . Cryptography is best to use. The software also has some integrated one program, also available in the Linux Operating System environments and Windows. Actually, it's free but there are versions that must be paid.
When you use "PGP" you have to have the data in binary form to be sent. So for email delivery at only design in the form of text. "PGP" also makes an encrypted message in the form of a segment if the file is too large.
Working principle of this algorithm "PGP" is when we apply this algorithm to send a message to our friends, "PGP" keys to make 2 pieces of public key and private key (Example Bob And Alice) and Bob and Alice will exchange their public keys.
When Alice sends Bob an email to the email will be encrypted with Bob's public key and Bob's Private Key, then the email will be sent through the network. If BOB wants to read the email then Bob must have a public key and the Allice key Private own.
