Even though Encryption sounds like high end techie jargon used by only programmers, it can very simply be explained a system of mathematical processes through which user data is encoded in such a way that only the intended user is able to read the message. With our daily online activity on the rise through media such as video calls, emails, online purchases and social media, encryption of information has become a necessity rather than an extra layer of protection. Encryption ensures that even if private data from your website gets into the hands of an unintended receiver, they will not be able to make sense of the same, thus protecting your website and its credibility.
Encryption in cPanel
cPanel supports encryption through GNU Privacy Guard (abbreviated as GnuPG) which is an open source software used by many a corporations to encrypt and decrypt messages using mathematical cryptography. While sending the information, the sender uses a public key of the receiver to encrypt the information. Upon receiving the message, the receiver then uses a private key to decrypt the information.
Now that we have taken a brief overview of Encryption and how it works with cPanel, let us take a look at how we can create, import and delete a GnuPG key.
Creation of GnuPG key
Through the following steps, you can create a GnuPG key using the cPanel interface: –
• Click on the “Encryption” icon (one with the key next to it) in the Email section of the cPanel link
• This prompts the system to create a New Key Interface. Here you will be asked to enter your name and email address.
• You can further use comments to help distinguish between multiple keys which you create
• Once you configure a key with the relevant details, you need to provide a strong key password and an expiration date. The expiration date ensures that the encryption you are setting up is time bound.
• Finally you need to select a key size and then click on the “Generate Key” button to generate your very own GnuPG key.
Import a GnuPG Key
If you have a pair of keys on your system already created, you can import them to cPanel by following the given steps: –
• In the Encryption interface, click on the “Import Key” button
• In the text box which is launched, paste your public key (make sure it includes the header and footer) and then click on the Import Key button to import the key.
Delete a GnuPG Key
If you want to remove a key from your cPanel, you can navigate to the desired key from the list of available keys and click on the “Delete GnuPG Key” button to remove the corresponding key.
We hope this article has helped you get familiar with the GnuPG keys and Encryption features of cPanel.
