Pretty Good Privacy: A Tutorial for Beginners to PGP

Keep all your online commutations secure, including the emails and messages you send with PGP (Pretty Good Privacy).

What's PGP?

This system is relatively safe, and the receiver can only access the sent message through password-protected private keys. Unauthorized people cannot pry on encrypted data, and as a user, you'll have nothing to worry about.

How does PGP work?

Pretty Good Privacy encrypts email and message content so that only the intended parties can view it. Typically, you need to install a program on your computer to work with an email client where all the sent emails go through PGP encryption.

Since it can be tiresome to encrypt an entire message, PGP uses an algorithm, a much faster encryption technique. The algorithm simplifies the process by encrypting the message and then using the public key encrypts the shorter key that encrypted the entire message.

After that, the sender transmits the short key and the encrypted message to the recipient, who then decrypts the two using a private key. In general, the algorithm supports data compression, combination of hashing, symmetric-key cryptography, and public-key cryptography.
