Note on Usage
This guide is recommended for a specific use case, in which you only use Thunderbird as a tool for email encryption, while reading and sending unencrypted email through their webmail interface in a browser or through a different client. https://skyeycleveland531.weebly.com/microsoft-project-2016-free-download-full-version-for-mac.html.
You can still use Thunderbird as your regular mail client, and we recommend it if you prefer to download your email to a secure device instead of leaving it in the servers of your email provider. For this latter case, we will recommend alternative settings in the relevant sections.
Thunderbird is a free and open source, cross-platform email client for sending, receiving and storing email. An email client is an application that lets you download and manage your messages — from multiple accounts with multiple providers — without a browser.
Gnu Privacy Guard (GPG) is free and open source software capable of encrypting, decrypting and digitally signing messages and files. It also generates and manages the public and private keys needed to do so.
Enigmail Enigmail is an add-on for Thunderbird to encrypt, decrypt and sign emails, and to manage PGP keys.
1.0 Things you should know before you start
You will need at least one email account to use Thunderbird. If you want to create a new account to use with Thunderbird, you can find a list of privacy-conscious email services here.
Like all email clients, Thunderbird makes a copy of your messages available on your computer. This includes the emails you send as well as those you receive. As a result, it is particularly important that you have full-disk encryption enabled if you intend to use Thunderbird. To do so, check that FileVault2 is enabled before starting this guide.
Thunderbird cannot protect your device if you open malicious attachments or click on malicious links. Do not open unsolicited attachments and exercise caution when clicking on links that were sent to you by email. Learn how to Protect your device from Malware and Hackers.
In order to better protect the data in your computer, we highly recommend making sure that your device is encrypted. To do so, check that FileVault2 is enabled before starting this guide.
1.1 Other tools like ThunderbirdBest Mail Client For Mac
Thunderbird is available for GNU/Linux, Microsoft Windows and macOS. Securely managing multiple email accounts is a complex task, and we strongly recommend Thunderbird for this purpose. However, if you prefer to use an alternative we recommend the following free and open source tools:
The security advantages of Thunderbird are significant, particularly when compared to commercial alternatives like Microsoft Outlook.
2.1 Download and Install GPG Suite
In order to encrypt your emails, you will first need to download and install GPG Suite, the encryption manager that enables your computer to encrypt your emails.
2.2 Download and Install Thunderbird
Thunderbird is an email client that can be used to download and send email, and that you can use together with an add-on called Enigmail to encrypt your email.

Make sure to launch Thunderbird before continuing to the 'Download and Install Enigmail' Section.
When you launch Thunderbird for the first time, you will see a warning popping up to ask you if you want to open an app downloaded from the Internet. Click 'Open'.
Note: When Thunderbird is launched for the first time, it will also ask if you would like to set up an existing email account. We will explain how to set up your email account in Thunderbird in the 'Link Thunderbird to Your Existing Email Account' section below. You can click 'Cancel' to continue following this guide, or, if you know what you're doing, set up your existing email account now.
2.3 Download and Install Enigmail
Enigmail is an add-on for Thunderbird to encrypt, decrypt and sign emails, and to manage PGP keys.

2.4 Link Thunderbird to Your Existing Email Account
If everything has worked fine, by clicking the 'Done' button Thunderbird will connect to your email server and download your mailbox. This operation will happen in the background and might take some time, depending on the size of your inbox folder and speed of your internet connection.
If you are using a Gmail account, you will be prompted to enter your password and 2-factor authentication code and to accept the connection to an email client.
2.5 Create a Private and Public Key: Your PGP Key Pair
Once your email account is connected to Thunderbird, you can start using PGP by creating a key pair, consisting in a private key, which you must store safely and never share with anyone, and a public key, which you can share publicly or with trusted people.
2.6 Generate a Revocation Certificate
While Enigmail is generating your key pair, you will also be asked to generate a revocation certificate. Generating a revocation certificate is important and you should click on the 'Generate Certificate' button in the prompt, and save the certificate in a secure location (like an encrypted USB stick that you keep for exclusive, personal use).
This file is needed only to revoke your key pair in case you lose your private key or there are doubts about it being compromised. The revocation certificate cannot be used to decrypt your PGP-encrypted communications.
The revocation certificate will allow you to securely discontinue the usage of your key at any time. It is very important to create a revocation certificate for future use and store it in a secure place that only you or trusted people can access and that is separate from the device where you keep your key pair. Revoking your key will prevent people from encrypting to the unused or compromised key, and signals to the keyservers that the key is no longer valid.
2.7 Generate a Revocation Certificate for an Existing Key Pair
If you did not create a revocation certificate while generating your key pair, you should do so now, following the steps below:
2.8 Back up Your Key Pair Somewhere Safe
Backing up your key pair in a safe location is important to be sure you will not lose it even if your device is lost or your hard disk damaged, or if you want to encrypt your emails with the same key pair on another computer.
2.9 Publish Your Public Key
Your contacts will need to import your public key to encrypt messages to you. To let others find your public key, you may upload your public key to a key server or attach the key in an email. Public keys uploaded to key servers are searchable by the email address used or PGP Key ID. Hazrat umar farooq history movie in urdu free download torrent.
Warning: If you don't want to disclose publicly that you're using encryption, for example because encryption is illegal in your country, you should avoid publishing your public key on the key servers. In such cases it's a good idea to only send your public key by email or through other means to your trusted contacts you exchange encrypted emails with.
To upload your public key to a keyserver, follow these instructions:

This section explains how to configure Thunderbird's preferences to help defend your system against attacks that originate in emails. For more information, see Protect yourself from Malware & Hackers.
3.1 OpenPGP Security
3.2 Autocrypt
Autocrypt is part of the default configuration of Enigmail.
Autocrypt aims at making encryption easier, but if it isn't properly configured, it may disable encryption automatically for some email addresses.
To set up Autocrypt properly, it is important to change some settings by following these instructions:
3.3 Enigmail Preferences
<a name='subject-encryption'></a>
3.4 Subject Encryption
Enigmail can also encrypt the subject of your message (please note that other metadata, like the sender's and recipient's addresses, will still be visible).
If the subject is encrypted, then the visible subject is replaced with a dummy text like 'Encrypted Message'. It is a good practice to encrypt your subject by default, but sometimes you may need to disable this feature.
In order to disable subject encryption, go to Enigmail → Preferences → click 'Display Expert Settings and Menus', then go to the 'Advanced' tab and uncheck the 'Encrypt subject by default' option.
3.5 Disable HTML and remote content
Email messages can contain content such as scripts in the HTML code, images, or stylesheets that can violate your privacy or be used for malicious intents. To protect your privacy and to mitigate the risk of attacks or vulnerabilities, it is always a good idea to disable HTML composition and rendering, and to block remote content.
3.5.1 Disable HTML email composition
3.5.2 Disable HTML email rendering

Remote content should be disabled by default in Thunderbird, but it's a good idea to check.
3.6 Add Your PGP ID to Your Email Signature
GNU Privacy Guard (GnuPG) is free cryptographic software that was developed by the GNU Project. This software is compliant with the OpenPGP standard and was designed to inter-operate with Pretty Good Privacy (PGP), another email encryption program that was initially designed and developed by Phil Zimmermann.
GnuPG relies on a form of public-key cryptography that requires each user to generate his or her own pair of keys. This key pair can be used to encrypt, decrypt and sign digital content such as email messages. It includes a private key and a public key:
GnuPG and Enigmail also let you attach digital signatures to your messages. If you sign a message using your private key, any recipient with a copy of your public key can verify that it was sent by you and that its content was not tampered with. Similarly, if you have a correspondent's public key, you can verify her digital signatures.
4.1 Download Your Receiver’s Public Key
https://technologybrown255.weebly.com/fifa-2007-crack-download-iso.html. Once the public key of the receiver is downloaded, you can send them an encrypted email.
4.2 Verify the Fingerprint of the Downloaded Public Key
To be sure that the public key you've just downloaded is the right one, and that nobody has tampered with it, it's a good practice to check its fingerprint. Cinema 4d free.
4.3 Write and Send an Encrypted Email
If your key reaches its expiration date, you can always extend it as long as you still have access to the private key. To do so, you can follow these instructions:
Q: What happens if I just install Enigmail and not GnuPG?
A: That's simple, really. Enigmail just won't work. After all, it's the GnuPG software that provides the encryption engine that Enigmail uses.

Q: How many email accounts can I set up in Thunderbird?
A: As many as you like! Thunderbird is an email manager and can easily handle 20 or more email accounts!
Q: My friend has a Gmail account. Should I convince her to install Thunderbird, Enigmail and GnuPG?
A: That would be ideal. Just make sure she configures all of her security settings in exactly the same way as you did. Then the two of you will have an extremely effective way of communicating in privacy and safety!
Q: I still don't understand the purpose of digitally signing my messages.

A: A digital signature proves that you're the real sender of a particular message and that the message hasn't been tampered with on its way to your intended recipient. Think of it as the electronic equivalent of the wax seal on an envelope, which contains a very important letter.
