Enigmail is a data encryption and decryption extension for Mozilla Thunderbird that <span class=\"st\">allows you to use OpenPGP to encrypt and digitally sign your emails as well as decrypt and verify email messages you receive. In order to use Enigmail, ensure that you have Mozilla Thunderbird installed and your email account setup. Check our previous article on how to install and setup Mozilla Thunderbird on Ubuntu 18.04.<\/span><\/p>\n<ul>\n<li class=\"entry-title td-module-title\"><a title=\"How to Install and Setup Thunderbird Mail Client on Ubuntu 18.04\" href=\"https:\/\/kifarunix.com\/how-to-install-and-setup-thunderbird-mail-client-on-ubuntu-18-04\/\" target=\"_blank\" rel=\"bookmark noopener noreferrer\">How to Install and Setup Thunderbird Mail Client on Ubuntu 18.04<\/a><\/li>\n<\/ul>\n<h2>Encrypt Emails using Enigmail on Thunderbird<\/h2>\n<p>By default, Thunderbird doesn&#8217;t ship with Enigmail extension and therefore you need to install this extension using Thunderbird\u2019s Add-ons Manager.

To launch the setup wizard, click <code>Enigmail tab<\/code> on the menu bar and navigate to <code>Setup Wizard<\/code>.<\/p>\n<h4>Choose the Setup Type<\/h4>\n<p>When the setup wizard launches, you will be prompted to choose the setup type.

This will create a <code>public key<\/code> which you will share with whomever you want to sent encrypted emails to you and <code>secret key<\/code> that you will use decrypt received emails signed encrypted with your public as well as sign the sent emails. To protect the secret key, you will need the passphrase. Hence, set a passphrase that you can easily remember and is secure at the same time. You can also define how long should the passphrase be remembered after decrypting an email message.<\/p>\n<p><a href=\"http:\/\/kifarunix.com\/wp-content\/uploads\/2019\/04\/create-key-pair.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-2558\" src=\"http:\/\/kifarunix.com\/wp-content\/uploads\/2019\/04\/create-key-pair.png\" alt=\"encrypt emails using Enigmail on Thunderbird\" width=\"744\" height=\"611\" title=\"\"><\/a><\/p>\n<p>Click Next to generate the key pair. Once the generation is done, you will be notified.

Be sure to store this key safely.<\/p>\n<p><a href=\"http:\/\/kifarunix.com\/wp-content\/uploads\/2019\/04\/revoke-crt.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-2560\" src=\"http:\/\/kifarunix.com\/wp-content\/uploads\/2019\/04\/revoke-crt.png\" alt=\"\" width=\"745\" height=\"601\" title=\"\"><\/a><\/p>\n<p>Once the revocation certificate generation is done, click Next to finalize on the Enigmail setup.<\/p>\n<p>You are now ready to encrypt outgoing mails. However, you can only encrypt emails if the recipient has shared with you their public keys. You can also read encrypted emails if they are encrypted with you public key. Therefore before both the sender and the recipient can encrypt or decrypt emails, they need to have shared their public keys with themselves.<\/p>\n<h4>Upload Public Keys to Keyserver<\/h4>\n<p>To share the public keys with the recipient with whom you would like to have encrypted email communication, you would compose a new mail and click Enigmail &gt; Attach My Public key then send your message. However, the easiest way would be to upload your public keys to public Keyserver such that both parties can pull the other&#8217;s public keys from there.<\/p>\n<p>To upload the your public key to Keyserver, Navigate to Enigmail tab on the Menu bar &gt; Key management. Right click on the Key you want to upload and select Upload Public Keys to Keyserver.<\/p>\n<p><a href=\"http:\/\/kifarunix.com\/wp-content\/uploads\/2019\/04\/upload-public-key.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-2562\" src=\"http:\/\/kifarunix.com\/wp-content\/uploads\/2019\/04\/upload-public-key.png\" alt=\"encrypt emails using Enigmail on Thunderbird\" width=\"760\" height=\"363\" title=\"\"><\/a><\/p>\n<h4>Download Public Keys from Keyserver<\/h4>\n<p>If your contacts have also uploaded their Public keys, you can similarly download them from Keyserver.
