What is e -mail encryption?

E -mail encryption is a way to protect electronic communication. It's like sending a message in a code. Only someone who knows the code can read what is written in e -mail. This allows you to send private information with an e -mail without worrying that an unintended person reads it.

E -mail has become a common way of communication. People use it for everything from maintaining contact with friends to business stores. E -mail encryption allows these conversations to be maintained private.

Sending the unencrypted e -mail is like publishing a message to someone to an office notice board. The intended recipient can see it, but also everyone else in the office looking at the Board of Directors. When e -mail encryption is used to protect the message, it is as if the message has been put in the envelope and placed in someone's mailbox. An unintended person can still read it, but it would be more difficult for the person to access.

One of the most common formse. This system uses two keys, a public key and a private key. The sender is the only one who has a private key. The sender can provide a public key to anyone who could send e -mail. The public key can even be openly released so that anyone can use it, even a complete foreigner, an e -mail to a person whose key is.

When someone wants to send this person an e -mail message, they can encrypt it using a public key. In this way, it can be decrypted using a private key. Anyone who did not have a key would see e -mail as a nonsensical string of numbers. The public key encryption system provides full security coverage only when both sides use it in conversation.

The common version of this type of E -mail encryption is called quite good privacy (PGP). It is used by many e -mail service providers. The system was created by Phil Zimmerman in 1991.

When you send -Mail afterThe power of PGP is first compressed. The system then creates a one -time secret key called the Session Key. This key is used to encrypt e -mail. The session key is then encrypted using the recipient's public key. When the recipient gets e -mail, his copy of PGP decrypts the session key and then uses it to decrypt the e -mail.
