OpenPGP is a tool for secure online communication. the Web Hosting CPanel 4 uses GnuPG for its public-key cryptography so that users may communicate
securely. Each person gets a pair of keys, called the public key and the private key. Each person's public key is published
while the private key is kept secret. Messages are encrypted using the intended recipient's public key and can only be decrypted
using their private key.
General documentation and comprehensive user guides are available at the GNU Privacy Guard site.
To generate a public and private key:
Click on the Manage OpenPGP keys link in the Tools area.
Click on the Add Key link.
Enter your name, email address, and nickname in the Your Name, Your Email, and Comment/NickName fields.
Enter the password for the key in the Key Password field.
Enter the expiry date for the key in the Expiry Date field. You can suffix the entered number with the following:
y = year
m = month
w = week
d = day
Choose the size of the key that you want to generate in the Key Size field. 1024 bytes is a common size.
Click on the 
button. Note that it may take a few minutes to generate the key, depending on its size.
