One of the popular software for encrypting of email transmission is PGP (Pretty Good Privacy). This software is very much popular to use encrypting entire email data smartly for avoiding data leakage uncertainty. It is not only useful to encrypt mail body, rather than it can be very popular on signing, encrypting or decryption feature for physical files, normal text, full directories, attach data, even whole data partition as well. As all the big companies are very much concern about hiding or encrypting their specific communication, PGP is one the common choice for them to use on any communication. The main utility of PGP is using a secret private key which only known to the tool and one shareable public key which is available for both sender and receiver. So the receiver can easily identify or verify sender secure identity to confirm the sender person security, and also can verify the proper integrity of the content shared by the sender. So it is very easy to understand for the receiver that mail is somehow tampered by someone in the network root or not.

A process of encryption & Decryption of PGP (Pretty Good Privacy):
Data – Generate Random Key – Encrypt data using this random key – Encrypt random key by receiver public key (X1) – encrypt random key by sender public key (Y1) – sending encrypted data to the receiver.
Encrypted Data – Decrypt X1 by receiver private key – Decrypt encrypted data by decrypting result of X1 (it actually the random key of earlier encryption) – display to the receiver.
