PGP does not compress messages. It encrypts them. PGP is used to ensure that confidential emails to do fall into the wrong hands, and that a message is in fact from the person you think it is.
• Developed by Phil Zimmerman in 1995.
• Documentation and source code is freely available.
• The package is independent of operating system and processor.
• PGP does not rely on the "establishment" and it's popularity and use have grown extensively since 1995.
• PGP combines the best available cryptographic algorithms to achieve secure e-mail communication.
• It is assumed that all users are using public key cryptography and have generated a private/public key pair.
• Either RSA (with RSA digital signatures) or El Gamel (with DSA) can be used.
• All users also use a symmetric key system such as triple DES or Rijndael.

Give two reasons why PGP compresses messages?
Ans 1: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 don't compress well aren't compressed.)
