I'll explain how to install PGP and the function of that particular software in network security...PGP is from a word Pretty Good Privacy, it is a public key enryption program originally written by Phil Zimmermann in 1991.Why PGP?For me, it is to secure email on internet because email is personal and it's private, beside that we don't want our private email or confidential documents read by anyone else. The advantages of PGP are language support and is available for many different platforms including Windows, Unix, MS DOS, OS/2, Macintosh and so on. After I do a research, the latest version of international freeware versions of PGP os 6.5.1i for Windows 95/98/NT and MacOS only while 5.0i for other platform.PGP works by combines some of the best features of both conventional and public key cryptography.PGP will compresses the plaintext that had been encrypt by user and creates a session key(secret key). Then after data is encrypted, the session key is then encrypted to the recipient's public key and transmitted along with the ciphertext to the recipient.
