cPanel – Encryption ”; Previous Next cPanel supports GnuPG or GNU Privacy Guard, which is an open-source software to encrypt and decrypt messages using cryptographic algorithms. GnuPG uses a public and private key infrastructure to implement this feature. When the sender sends a message, he encodes it with a public key of the recipient. The recipient after receiving the message, decrypts the message with his private key, which is available in the server. This feature helps in sending emails with sensitive information, as without a private key, it’s nearly impossible to decode the message. Create a GnuPG Key To create a GnuPG key, follow these steps − Step 1 − Open cPanel Email Encryption by clicking on Encryption in the Email section of the cPanel Link. Step 2 − In create a New Key interface, Enter Your name and Email. Step 3 − Enter comment or nick name; you can use this to distinguish between multiple keys. Step 4 − Enter Strong Key Password and Set Expiration Date. Expiration date can be set like y for year, e.g. 1y for 1 year w for weeks, e.g. 2w for 2 weeks d for days, e.g. 4d for 4 days Step 5 − Select key size from dropdown; larger key sizes are more secure. Step 6 − Click Generate Key; it will take a few minutes to generate your key. Import a Key If you already have a key pair in your local computer, then you can import them to your cPanel. You can only import the Public Key. To import a GnuPG key, follow these steps − Step 1 − Scroll down to find Import Key in Encryption Interface. Step 2 − Click on the Import Key Button. You will be taken to a new interface. Step 3 − Paste your Public key in the text box; make sure it includes both the header and footer rows. Step 4 − Click the Import button to import the key. Delete or View the Key Step 1 − Scroll down in Encryption Interface to find the list of keys. Step 2 − To view a key, click View corresponding to the Key you want to view. Step 3 − To delete a key, click Delete GnuPG key, it will ask for confirmation, click yes to delete the key. Print Page Previous Next Advertisements ”;

cPanel – Simple Zone Editor ”; Previous Next DNS (Domain Name System) is a very essential part of Internet System. It simply maps a FQDN (Full Qualified Domain Name), which is in human readable form. For example, www.tutorialspoint.com to IP address, which are used by computer machine, e.g. 117.18.237.191. For this process, DNS uses zone files that are stored in servers, which contains resource records to map a domain name to an IP address. In this Simple Zone Editor, we can add two types of records − Add an A Record The A types of resource records are Host Name records. They contain the IP address of a specific host, and maps the Domain Name with 32-bit IP address. To add an A type record, perform the following steps − Step 1 − Open the Editor by clicking Simple Zone Editor found in Domains Section of cPanel Home. Step 2 − Find Add an A Record in the Simple Zone Editor interface. Step 3 − Enter Name in Name textbox and IP address in Address textbox. Step 4 − Press Add an A Record. If successful, you will get a success message. Note − ‘A’ records are essential for accessing your website. They allow DNS servers to locate your website and its services. Without an ‘A’ record, visitors can’t access your website. The cPanel automatically configures A type records for your domain and website, as soon as they are created. Add a CNAME Record The CNAME records are used to add an Alias to its associated domain name. You can point multiple CNAME records to a single A record. So that when the DNS looks up for the Alias, you can simply rename a host, which is defined in the A records. To add a CNAME record, please follow these steps. Step 1 − Scroll down on Simple Zone Editor to find Add a CNAME Record. Step 2 − Enter the desired Alias name for CNAME record on Name textbox and Enter a FQDN in CNAME textbox to which you want your Alias pointing to. Step 3 − Click Add CNAME Record and you should see a success message. Remove an A or CNAME Record To remove a user defined A or CNAME Record, please scroll below on Simple Zone Editor to find User–Defined Records. Press the Delete link corresponding to the Record you want to remove. You should see a success message when record is deleted. Print Page Previous Next Advertisements ”;
