Pretty Good Privacy or PGP is used by commercial email providers for the encryption. PGP is a very powerful tool to convert text into code. Although its name is quite the contrary to its attributes as this encryption method along with other heavy encryption is utilized for communication by the government.

PGP was created by Phillip Zimmerman in the year of 1991 for the study and analysis of the coding methods and codes. Zimmerman adopted a method to use the PGP for encryption and decryption purposes with help of using a specific system and public-key for the encryption. Username and other data are sent to the destination in an encrypted form with help of internet. When it reaches its destination it is decoded for the user.

Pretty Good Privacy encryption code works in such a way that the when an email is sent to a destination it converts into a code. This encrypted code is secure and safe. Even if the email is hacked or intercepted in the middle it would appear like a mumbo jumbo of lines and letters. The email once reached to its expected destination would be decrypted with help of a key or password. Only the user with the right key or password can decode this encrypted mail. This is a secure means to transfer data used by many commercial email providers as it provides enhanced safety.

We can understand public-key cryptology or encryption with help of this example. Such as many people have mailbox in front of their houses. Usually it’s locked so that no one can hamper with the mails present in the mailbox. The front slot of this mailbox is used for putting letters in it. The same method is applied in the case of email sending to the user mailbox that is virtually present online.

For the reason of enhanced safety and increased security maximum risk is avoided with means of acquiring a digital signature of the sender. This digital signature is verified at the destination with help of specific software. This software checks the integrity of this mail and also verifies its message authentication. The algorithms used for digital signature are called RSA and DSA. Any legal document that can be used in the court is encrypted the same way by creating a digital signature.

Usually this method is used commercially and commonly but not in the case of Zimmerman who has yet added another feature called the web of trust. Due to this method the username or password that do not exist virtually online are avoided so the data is safe from any potential risk of ending up in the wrong hands. This method is best for the confidential data transfer.

This method helps point out the wrong public key address and identity certificates make it sure that the email reaches the relevant address. PGP or Pretty Good Privacy is the best and safest way for the data transferring that is next to military-grade encryption so far. It is by far the most difficult encryption method that none of the leading cryptographers can decode.
