Weekly Tips: Protect Confidential Information with PGP in Zoho Mail

Weekly Tips: Protect Confidential Information with PGP in Zoho Mail

We deal with confidential information almost every day, whether it is being sent out or received. Though emails sent using Zoho Mail are encrypted both during transit and at rest, attempts to access and steal your sensitive data are always a threat that we fear, which can result in potential data theft. This raises an important question: So, how can we send and receive confidential information over email without worrying about the email being intercepted, compromised, or accessed by unauthorized individuals?

That is when you can take advantage of Zoho Mail's PGP (Pretty Good Privacy) integration to handle sensitive information via email.

What is PGP?

Pretty Good Privacy (PGP) encryption helps users to send encrypted emails to their recipients, ensuring privacy and security of their email content. PGP uses a pair of keys (Public and Private) to encrypt and decrypt emails. In addition to encryption, emails can be digitally signed by hashing, ensuring the legitimacy of the sender.

Let's say : John wants to send a secure message to Sam. Then Sam generates a public and private key pair. The public key is shared with John, while the private key remains secret with Sam.

John encrypts the email message using Sam's public key and signs it with his own private key. When Sam receives the message, he decrypts it with his private key, after entering the passphrase for it.


Enable PGP

The users in an organization can access PGP integration only when the organization admin enables it from the Zoho Mail Admin Console. Follow the steps mentioned below to enable PGP for your account:
  1. Log into your Zoho Mail account.
  2. Navigate to Settings >Integration.
  3. Click on PGP.
  4. You can either Generate a new key pair or Import keys.
  5. keys that have been added will be displayed under Key Management.
Once PGP has been enabled, all emails you send out will be PGP encrypted.
