Platforms continuously extract your data, communications, and attachments. Therefore, it is necessary to use encrypted email platforms like Mailvelope to send anonymous emails. Want to know how to set up encrypted email in Gmail? We have covered everything step-by-step on how you can configure Mailvelope with Gmail.
Over the last few years, we have repeatedly witnessed that our communication mediums are no longer secure. We witnessed that the information extracted via emails was destructive at worst and damaging at its best. That also reminds us that whatever we consider safe should not be perceived this way.
Emails are considered to be a hoard of information. Therefore, we should think carefully before including information in our emails. Otherwise, we should spend a little time considering ways to secure our emails from prying eyes.
OpenPGP for email encryption
OpenPGP has been derived from the Pretty Good Privacy (PGP) protocol. Phil Zimmermann developed this protocol in 1991. This PGP protocol is a non-proprietary protocol for encrypting email using public-key cryptography.
In 1997, the IETF – Internet Engineering Task Force formed the working group, i.e., the OpenPGP, whose focus was to take the once proprietary PGP protocol, which Zimmermann developed. In 1997, it became an IETF proposed standard under RFC 4880. By doing so, it has become the preferred means of encrypting emails.
Mailvelope for webmail email encryption
Email encryption will only work if we integrate it into our daily workflow. This means that we need to incorporate email encryption into our browser, which we preferably use.
Mailvelope has remarkably gained an appreciation for its easy-to-use interface and ease of integration. It is a browser-based extension that works with many popular browsers, such as Firefox, Chrome, Opera, etc.
For security freaks, it is good to know that nothing is shared back with the networks as the keys are maintained client-side. However, there are some inherent risks associated with browser-based extensions. They retain things like an individual’s Private keys for things like GPG. Nonetheless, it narrows to an individual’s risk posture like other security-related things.
Configuring Mailvelope with Gmail
Below are the steps we followed to configure Mailvelope with Gmail. So, if you are interested in giving Mailvelope a try, then this tutorial will help you get started with:
- Install the extension
On a Mac, you can navigate to Windows. Then click on Extensions > Get More Extensions. Use the search function to search for Mailvelope.
- Navigate to the Mailvelope options panel
The extension will automatically add a menu option to your preferred browser, like the one shown below:
By clicking on the lock with a key, you will navigate to the Options. Here, you will see the options button on the menu:
- Create your private/public key pair
You will be directed to the options page; thus, if you have existing keys, you can upload them. However, if that is not so, then you can easily create a new pair:
The Generate Key option is the one that you get you started, and you will see a page like this one:
The key should be for the email for which you want it, whereas if you have various emails, you can create the key for all your emails. The password is what you need to decrypt the encrypted emails, so you mustn’t forget it. However, the password should be complex, lengthy, and unique rather than simple and easy to guess.
The key will be generated once you click on Submit. A success message will be shown if the key is successfully generated. Just like the one depicted below:
You will find the keys in your Key Manager. You will be able to locate it as Display Keys in the Mailvelope menu options:
- Add and share your public key
The only issue you will encounter would never be with the configuration; instead, to make Mailvelope work, you will require the participation of people. However, if it is not so, then you can have PGP configured and read, but there will not be a single person with whom to use it. The fundamental details will help you to share your public key:
Only the Public key will be shared. The Private Key will be kept to your own, and you are asked not to share it at all costs. To import, you will navigate to Import Keys in the menu options, and the recipient’s public key will be uploaded.
- Send your First Encrypted Message
You can send your first email once you have someone to communicate with. Once you open your email client, a new option will appear in the email, allowing you to encrypt it. You can now type in your message by clicking the new editor button in the email and through the new pop-up form.
In the image below, you can see that it will carry your existing email signature.
When you are done with the message, click on Encrypt. After that, select the individuals you want to encrypt for (Note that you will need someone else’s public key to make this work). It is of prime importance that you select your email and then your recipient’s email because if you don’t, you won’t be able to read your own email.
A mess will appear after you click on Ok.
Once you click on Transfer, this mess will be pushed to the email, which is now ready to be sent to the recipient(s).
Once an email message is decrypted, the recipient receives the message. This is how it looks when a recipient gets something through the Gmail web client.
The importance of privacy
The original meaning of the word “privacy” seems to be long forgotten. Going online with a mindset of browsing privately is no longer possible. The various communication mediums we trust to provide us with the promised security rarely stand by their promise. It would help if you kept in mind that whatever you share will likely be consumed by someone other than those you intend to share your stuff with.
However, with advanced technologies like OpenPGP, we can ensure the privacy of our shared content. Mailvelope not only assures us of privacy but also makes it practical. However, if you are unsatisfied with Mailvelope, you can use other options like Protonmail, Dashlane, etc.
