Thunderbird waa ^{(Thunderbird)}macmiil^{(free email client)} caan ah oo lacag la'aan ah oo la socda sifo weyn. Waxaa isticmaala dad badan waxayna leedahay waxyaabo badan oo lagu daro kuwaas oo loo isticmaali karo in lagu kordhiyo shaqeynteeda iyo muuqaalkeeda. Guud ahaan, iimaylada waxaa lagu soo diraa shabakada aan la aamini karin ee u nugul khataraha amniga. Si aad u ilaaliso in xogtaada ay soo gaarto kuwa aan la rabin, waxaad u baahan tahay inaad geliso hab sir ah Thunderbird .

Iimeyllada Thunderbird waxaa la soo diraa iyada oo aan la qarin oo waxay u nuglaadaan in la dhegeysto tuugada iyo kuwa soo dhex gala internetka. Thunderbird ma lahan awood dhismeed oo lagu sugo iimaylka, si kastaba ha ahaatee, waa la sirin karaa iyadoo la kaashanayo PGP, GPG suite iyo Thunderbird kordhin loo yaqaan Enigmail^(Enigmail) . Enigmail waxa uu ku xidhaa aalada GPG si loo hirgaliyo sirta

Maqaalkan, waxaan kugu hageynaa sida loo sireeyo oo si dhijitaal ah loogu saxiixo iimaylada Thunderbird iyadoo la adeegsanayo borotokoolka sirta guud ee caanka ah ee loo yaqaan macmiilka Pretty Good Privacy (PGP) iyo aalad GPG oo ku saleysan macmiilka PGP . In kasta oo kordhintu ay daboolayso macluumaadka xasaasiga ah ee aad u dirto shabakad aan la aamini karin, sirta guud ee sirta guud ma qarin karto xogta daah-furnaanta ah sida khadka mawduuca iimaylka, Laga soo bilaabo^(From) iyo Ciwaanada maadaama ay kuwani u baahan yihiin inay caddaadaan si xogta loogu hago isticmaalaha ugu dambeeya.

How to Encrypt and Digitally Sign a Thunderbird email

Thunderbird is a popular free email client that comes with great feature. It is used by many people and has numerous add-ons which can be used to extend its functionality and appearance. Generally, the emails are sent over the untrusted network which is vulnerable to security threats. In order to protect your data being exposed to unintended intruders, you need to put in an encryption mechanism to Thunderbird.

Emails in Thunderbird are sent without encryption and are vulnerable to eavesdropping from the internet hackers and intruders. Thunderbird doesn’t have a built-in capability to secure the email, however, they can be encrypted with the help of PGP, GPG suite and a Thunderbird extension called Enigmail. Enigmail connects to the GPG tool in order to implement the encryption.

In this article, we guide you on how to encrypt and digitally sign emails on Thunderbird using a popular public key encryption protocol called Pretty Good Privacy (PGP) client and a GPG tool that is based on PGP client. While the extension camouflages the sensitive information you send on an untrusted network, the public key encryption cannot encrypt the transparent data like email subject line, From and To addresses as these need to be clear in order to direct the data to the end user.

Encrypt Thunderbird Email

Download and Install the GPG Suite

GPG Suite is a package used to encrypt and decrypt the email messages. The GPG tool is based on PGP client and it is available for free. This is an open source project which can be installed with just a few clicks. Following steps will explain how to install the GPG suite.

• Download the GPG suite file here.
• To mount the image, Double click on the downloaded file and click on the Install button to install the GPG Suite.

Download and Install Enigmail in Thunderbird

• Launch Thunderbird and navigate to Tools.
• Click Add-ons and search for extension Enigmail.
• Hit the Add to Thunderbird button and once the installation is complete a new option called OpenPGP will be added to the menu.

Creating PGP keys

Follow the below steps to create your public and private keys.

• Navigate to OpenPGP and click Setup Wizard.
• Choose the option Yes, I would like the wizard to get me started and click the Next button.
• In the new windows that pops up, Select the appropriate option if you want to sign all your outgoing email by default and click the Next button.
• In the new window that pops up, Select the appropriate option if you want to encrypt all the outgoing email by default and click the Next button.

Now the Wizard will display email settings which you can change to make sure there are no problems with signing and encrypting email on your machine. You can choose the option No if you have already made a change to few default settings in order to make OpenPGP work better on your machine else you can select Yes to let the Wizard configure your email settings to make OpenPGP work more reliably.

• Next, create a new key pair to Sign and encrypt email. Here you can either use one of your existing keys to sign, encrypt and decrypt emails; or you can choose to create a new key pair for signing and encrypting email.
• If you want to create a new key pair for signing and encrypting email, click the Next button.

In simple words, creating a key pair is nothing but a generating public key and private key. In cryptography, the public key is shared with people who want to send you an email. The public key of a recipient is used for email encryption. The private key, on the other hand, is associated with the public key and is used for decrypting the encrypted email message.

• Enter the passphrase and click Next. This passphrase is essential to protect the private key.

In the Summary page, click the Next button to create a new 2048-bit OpenPGP key.

At last, you will be prompted to generate a revocation certificate. You can either choose to Skip or Generate a Certificate which can be used to invalidate your key in case your secret key gets lost or compromised.

Verify the Setup

Follow the below steps to check if everything is set up correctly

• Navigate to Tools
• Select  Account Settings from the menu
• Select the account for which you generated key pair.
• Select OpenPGP Security from the menu.
• Make sure the option Enable OpenPGP support (Enigmail) for this identity is checked.

Also, the option Use specific OpenPGP key should be selected

Digitally Sign & Encrypt Thunderbird email

Once the Enigmail is setup the next step is to encrypt and decrypt the email. Follow the below steps to Sign-in and encrypt the Thunderbird email.

Launch Thunderbird and compose a new email.

Navigate OpenPGP. Select the option Sign Message and Encrypt Message from the drop-down menu.

Click on the option Attach My Public Key to add a public key to the email. Enigmail gives an option to attach the public key on the email compose window or lets you upload the public key to public keyserver that can be accessed by anyone.

Give the recipients public key to encrypt email.

Once done your message will be encrypted and sent.

To decrypt the encrypted message, you need to give the passphrase in order to display the message as any other email.

That’s all.
