So if you’re ready to go “all in” with email pgp, this post is for you.
Let’s dive right in.
What is pgp?
Sending your sensitive information through the internet is always a big risk.
If you send your sensitive information through the internet using email or social media applications like facebook or whatsapp it is always a big risk.
But why is it a big risk?
Because hackers can break into your accounts and see your most important information and most important documents that you have sent in the past and now.
What if a hacker gets your bank details that you have sent to your wife?
Or someone else sees that you will be on vacation outside the country then he can steal your house. Or he can know that you will be on a vacation outside the country in the next month.
He can steal your house because he knows when no one will be in the home.
But there is a solution for all this problem.
You can encrypt your emails before sending them so if someone hacks your email account he can’t read your email because they are encrypted.
You can use tools like PGP or GPG to encrypt your emails before sending them.
PGP was created back in 1991 by Phil Zimmermann, but it is not free software.
For this reason the IETF (Internet Engineering Task Force) created openPGP and it is an email encryption standard that is implemented by multiple software .
So openPGP is like a free version of PGP.
OpenPGP was originally derived from the PGP software.
There is also GPG, a free and open source software tool that implements openPGP standard and it is used to encrypt emails too.
How does PGP actually work?
PGP uses public key encryption so if you want to send an encrypted email by using PGP then the first step is to get the public key of the recipient.
The second step is to encrypt your message by using the recipient's public key.
And then you will send the encrypted email to the recipient.
When the recipient gets the email he will use his public key to decrypt your message.
What's the Difference Between PGP, OpenPGP, and GnuPG?
So what is the Difference?
PGP:
Created by Phil Zimmerman in 1991, and it is not free software.
OpenPGP:
The OpenPGP created by the Internet Engineering Task Force (IEFT).
GnuPG:
It is a free software that you can use for free unlike PGP and is an implementation of the OpenPGP standard.
How To Use PGP Encryption.
If you want to use PGP then you will need to create your own PGP keys and then you will secure your PGP keys by using passphrase.
When you create your keys you will need to share your public key so if someone wants to send you an encrypted email he can find your public key.
If your public keys are created and you have shared your public key then now you can start sending and receiving encrypted emails.
Now you can Read your messages.
