First download it from here:
http://www.gpg4win.org/
Deselect everything but GPA......"It's the only thing you are going to really use and everything else will confuse you!"
After everything is installed on your pc, open the program..
Click key -> Generate...... A new window will open that looks like this...
Follow the instructions on entering your name, email and then passphrase.. "Make sure that you have a strong passphrase."
After you finish, your original window will appear and it will look something like this..
You are going to want to right click on the name you just created and click export. Choose a name and location of where you want to save your key.
"This is the key that you will use to have messages sent back to you with your email. It encrypts your name and email."
After you do this, if you want to view what you just created, you will click on the file and open it with notepad. It should look something like this:
This should look familiar to you... This is the same type of key that you see on SR.... That key that you see on SR that looks like this, needs to be copied and saved to notepad also. After doing that you can enter in that SR account into your Gpg4win.. You do this by clicking import and then grab it from the location you saved it.
IMPORTANT!! You are going to want to set the trust of the person you are sending your information to. Do this by right clicking on their name and selecting set owner trust. A new window will appear and Select where it says FULL. (DO THIS BEFORE YOU CONTINUE TO THE NEXT STEP)
Next you are going to want to create a message for the person you are sending it to.
Click clipboard and create your message, then click encrypt.. After clicking encrypt you will have another window open that looks like this:
Select the SR account that you are wanting to send your message to then click ok.
After doing this you will get another window that looks like this:
"you are not given an option to save this text, so copy it and save it to notepad."
Whenever you send and receive a message like this and you want to view it, just click verify. A dialog box will appear asking for your password. Enter in your password and the message above will show your message you created.
When you send your encrypted message to the person on SR you will just copy and past the whole line of text and send it to them. They will be able to decrypt it on their side.
That should just about do it for encrypting a message with this program. Hopefully you wont have any problems doing this. It is kind of a lengthy process at first, but once you get it down it wont take you long at all to do it.
