Privacy issues off late have raised some eyebrows. While most of us don’t take privacy seriously, we should, considering there’s constant news of password leaks, hacks and what with various security agencies taking a look at all our conversations. We already listed down the messaging apps you can use for private conversations & chats but what about emails? Well, don’t worry, as we are here to let you know.
There are a number of ways to encrypt emails. Some email services support it natively, while some don’t. There’s also this case of desktop clients supporting email encryption while their web versions don’t. So, to save you of all the fuss, we are listing down ways to encrypt emails on your favourite email services like Gmail, Outlook, Yahoo Mail and Apple Mail.
There’s also a way to send encrypted emails through any email service, so you can use that in case your email service doesn’t support it. Lastly, we are also listing down independent email clients that are aimed at encryption of your mails. So, check out the ways and it’s up to you to decide which method you want to use.
How to encrypt emails in Gmail
Gmail does not support encryption natively but you can get the feature through a third party extension on Chrome, Firefox or Safari browser. There are a few Firefox & Chrome extensions that bring encryption to Gmail but in our testing, we found these two to be the best: Mailvelope (available on both Chrome and Firefox) and SecureMail.
Mailvelope is the more advanced of the two, as it brings end to end encryption and works with a number of email providers including Gmail, Outlook, Yahoo Mail and GMX. SecureMail on the other hand brings basic encryption features and only supports Gmail. Using Mailvelope & SecureMail is pretty simple, once you install one of the extensions and set up your security key, it integrates with your email client and you can send encrypted emails with ease. Overall, these extensions work as they are supposed to and they indeed make your mails more secure.
Note: The recipient of your encrypted email through Mailvelope or SecureMail needs to have the Mailvelope or SecureMail web extension installed to view your email.
If you are using Safari, you can use extensions like Pandor and Criptext Mail that integrate with Gmail’s interface to let you send encrypted emails with ease. Other than that, you can add your Gmail account in encryption supported desktop clients like OS X’s Mail app and Microsoft Outlook to send encrypted emails.
How to encrypt emails in Outlook Mail
While Microsoft Outlook desktop client does support native email encryption, Outlook Mail on the web doesn’t and you will have to use the above mentioned Chrome & Firefox extension Mailvelope, which works with Outlook Mail as well. The Mailvelope extension integrates with the Outlook Mail’s compose window to let you send encrypted emails with ease.
How to encrypt emails in Yahoo Mail
Yahoo announced in early 2015 that it will be unveiling its own plug-in for Yahoo Mail that will bring end-to-end encryption but we are yet to see that promise come to fruition. Like Gmail, there’s no native way and you have to depend on third party apps and extensions. Thankfully, the above mentioned Chrome & Firefox extension Mailvelope supports Yahoo Mail as well. The web add-on integrates with Yahoo Mail to easily compose encrypted emails. As with Gmail, there’s one more way, that’s adding your account to a Apple’s Mail app or Microsoft Outlook, which support email encryption.
Note: Mailvelope on Chrome & Firefox supports Gmail, Outlook Mail, Yahoo Mail, GMX, Posteo and Web.de.
Desktop Email Clients
How to encrypt emails in Microsoft Outlook
Microsoft’s Outlook email client supports email encryption natively, which is a great plus for its users. The email encryption works can be set up on the Office Outlook desktop client. Here’s how you can do it:
- Open the Microsoft Outlook desktop client, which should be under the Microsoft Office folder in the Start Menu.
- Click on the “New” email button.
- Click on the “more options” expand button in the lower corner of “Options” tab.
- The “Message Options” dialogue box will open up, which has a button for “Security Settings” on its right.
- Go to security settings and tick “Encrypt message contents and attachments“.
- If you haven’t sent an encrypted email before, you can click “Change Settings” in the “Security Settings” dialogue box.
- In the settings, you can change the cryptography format, signing certificate and more.
Note: Microsoft Outlook desktop software supports third party (Gmail, Yahoo mail etc..) email accounts, so basically you can login with any email account on Microsoft Outlook and get the ability to send & receive encrypted emails.
Along with the native method, Microsoft Outlook desktop client supports a number of plugins like CipherPost, Sendinc etc.. for advanced email encryption.
How to encrypt emails in Apple Mail
The Apple Mail application on OS X and iOS does allow users to encrypt emails natively. It’s a very simple process and here are the steps:
- Open the Mail app and click the “Mail” tab on the top.
- In the Preferences dialogue box, click on the “GPG Mail” tab.
- In the “Composting” option, simply tick the boxes for “Encrypt new messages by default” and “Encrypt drafts“.
- Once you’re done, you’ll see a lock-unlock button on the right end of “Subject” in the Compose window.
- You can lock it to encrypt the mail or unlock it to not use any encryption.
Note: The same steps can be used in the Mail app of iOS devices to encrypt emails. Apple Mail app on OS X and iOS supports third party email accounts, so you can add your Gmail or Yahoo Mail or Outlook account while using Apple’s encryptions features.
Send encrypted messages from any email service
There’s no extension on Safari browser that supports email encryption for Outlook Mail and Yahoo Mail. Internet Explorer and Microsoft Edge users also don’t have the benefit of extensions that bring email encryption support. This is when independent third party text encryption services come into play. With these message encryption services, you can send encrypted emails from any email service and client.
There are various tools online that let you encrypt your text messages with ease. Inforencrypt is a simple text message encrypter, which is easy to use and gets the work done. You just need to enter the text you want to encrypt and set a password for it. You can then copy the encrypted message and paste it in the compose box of whichever email client you use. The recipient will be able to decrypt the email on Infoencrypt’s website by just pasting the code and entering the password. You can also try some other text encryption online services like Encrypt Easy. If you want a simple way to encrypt your text messages, this is your best bet.
Secure Web Email Clients
