PGP - Pretty Good Privacy Explained
The use of encrypted mails presents a valuable tool for hightened security and assurance that sensitive information does not get sniffed during transit. Here, we present the very basic of what PGP can do and if required, helping our client deploy PGP effectively.
PGP combines some of the best features of both conventional and public key cryptography. PGP is a hybrid cryptosystem. When a user encrypts plaintext with PGP, PGP first compresses the plaintext. Data compression saves modem transmission time and disk space and, more importantly, strengthens cryptographic security. Most cryptanalysis techniques exploit patterns found in the plaintext to crack the cipher. Compression reduces these patterns in the plaintext, thereby greatly enhancing resistance to cryptanalysis. (Files that are too short to compress or which do not compress well are not compressed.)
There is a few variants of PGP out there that are [free].
