Send Encrypted messages to your friends using GPG

There are actually many ways gpg can be used, but I am showing you the easiest one

First of all, make a file, and write some text in it.

Then, go to terminal, and go to directory where the file is kept.
Lets assume, the file name is myf.
Now, use this command:

Code:

gpg --symmetric myf

It will ask for a passphrase ( password )so that the person who knows this passphrase can decrypt your file
When you are done, it will create a file like
myf.gpg

Which is the encrypted version of your myf file

So, how do you decrypt it?
It is simple. Simply use this command:

gpg -d myf.gpg

And it will ask for your password.

How about testing this?
I am going to give you an encrypted file.
