The data encryption program for computers was created a few years ago by an antinuclear activist, Phil Zimmermann. A key-generation and encryption and decryption system, known as PGP (Pretty Good Privacy) were designed by him for the bulletin board systems, which were the pioneer of email, forums and web.
The algorithmic scrambling of information played a key role in the development of internet over the years. Encryption in particular is one of the vital elements in the e-commerce and perhaps this is one of the key reasons why governments have pulled back their stance to direct this confidential communication method.
Everybody can choose to encrypt their emails. Some email service providers have adapted to the open source versions of original PGP that is called OpenPGP.
How It Works
• A message is encrypted by PGP with the use of a symmetric encryption algorithm and symmetric key algorithms are secretly shared between the parties. However, it may not be secure because the key is known to both parties.
• The symmetric key is also called a session key and can be used only once. In turn, public key cryptology is used to encrypt it to protect it at the time of transmission.
• Public key, or asymmetric key, cryptology employs digital signatures and is based on mathematical formulas, which are apparently not possible to guess. It means that one cannot guess a private key from a public key, and vice versa.
• Different integrity checking and authentication are carried out by the use of digital signature, certificated designed by trust signatures and so on.
• You can try one of the commercial, or third party solutions out there in the market.
A desktop solution provider of OpenPGP, Hushmail is a desktop solution provider of OpenPGP and uses a web browser interface without any disruptive advertising.
The Android and iOS OpenPGP solutions incorporate iPGMail for iOS and APG while Gnu Privacy Huard for Android.
