Encrypt a Email Client and Setup a Secure Channel For Communication

 

What is E-mail Encryption ?

--> Email encryption involves encrypting, or disguising, the content of email messages in order to protect potentially sensitive information from being read by anyone other than intended recipients. Email encryption often includes authentication.

Why E-mail encryption is important ?

--> The goal of email encryption is to prevent all kinds of inadvertent release of sensitive data, whether it's because an unauthorised user gains access to the email communications channel or if an internal user accidentally emails it to the wrong recipient.

--> And Second thing you can't blindly trust any email service provider, because you can see that while you receive some kind of invitation mail or something they will suggest you replies like Thanks for inviting and related to that, It is only possible until they read your mails so you can't relay on any service provider, So this is very important thing to setup.

Once you setup then your are private while mailing others.(This has to setup at both the entities).

Step 1:- Firstly install Mozilla Thunderbird mail client and gpg4win on your windows.

From given below website links:

Now Click New Key Pair button

Step 5:- Now Kleopatra will be opened. In that you need to fill your details you entered earlier. Then click ‘Create’.

Step 6:- As you can see below it will ask you for Passphrase for your email encryption.

As soon as you click ok it will provide you with one more key that you need to save it.

NOTE: This is public key.

Press Finish.

Step 7:- When someone sends you an encrypted mail using your public key you need to decrypt it by Entering your private key. And then you can easily view the mail in simple text.
