Thanks Happy Tux again for taking time to help me.
You might recall that you taught me download using the 'wget' command.

So you could either use 'wget' command or just double clicking.

In the above two methods, it is impertive to use the 'import' command to attach to your key ring.

However, if you use 'recv-keys' command, the job is simple. I meant it goes directly to the key ring.

So there are 3 ways of downloading a public key.

Please tell me if understood incorrectly.

Your welcome. Yes that is correct the first two only download/open the file once you have saved that file to local disk you need to --import to keyring with the last --recv-keys being the best method to use because it goes directly into the keyring.

Thanks Happy Tux


Let us say that I want to encrypt a file on my system. I am not going to send it to anyone.
I just want to keep it on my system as an encrypted one.

Let us assume the name of the file is ' trial1000.txt'


[root@c83-250-110-112 nissanka]#gpg --encrypt --recipient Nissanka De Silva trial1000.txt
OR
[root@c83-250-110-112 nissanka]#gpg -e -r Nissanka De Silva trial1000.txt

The following is my user id. I could see it when I wrote the command [gpg –list-keys]
uid Nissanka De Silva (Le Grand Homme) <nissanka@swipnet.se>

'''''''''''''''''''''''''''''''''''''''''''''
To decrypt the file, when I want, the following command is the correct one.

[root@c83-250-110-112 nissanka]#gpg --output trial1000.txt --decrypt trial1000.txt.gpg

Please tell me if I am wrong.

Essentially correct except you need to use gpg --encrypt --recipient "Nissanka De Silva" trial1000.txt with the " around the name so it will find it in the keyring.
Yes then you will be asked for the passphrase to decrypt.

Thanks Happy Tux

Please look at the following:
--------------------------------------------------------------------------------------------


I wrote a letter and saved it on the following folder.
The name of the file is ' Testing for pgp(1).doc '
I just want to encrypt and keep it on my computer.

----------------------------------------------------------------------
[root@localhost nissanka]# gpg --encrypt --recipient 'Nissanka De Silva' 'Testing for pgp(1).doc'
gpg: can't open `Testing for pgp(1).doc': No such file or directory
gpg: Testing for pgp(1).doc: encryption failed: file open error
[root@localhost nissanka]#
---------------------------------------------------------------------
Why didn't it work? I guess the file is on another folder and it couldn't find it. I guess this will work if I copied the file to ' /home/nissanka/
How do I do without copying it on to the /home/nissanka ?
Please help me.
----------------------------------------------------------------------------
/home/nissanka/Documents


/home/nissanka/Documents/Testing for pgp(1).doc

You would need to include the path to the file eg gpg --encrypt --recipient 'Nissanka De Silva' Documents/'Testing for pgp(1).doc' or change to the Documents directory before issuing the encryption command.

Thanks Happy Tux. You were very quick to answer. The following is the output now. Did it work now?

[nissanka@c83-250-110-112 ~]$ su root
Password:
[root@c83-250-110-112 nissanka]# gpg --encrypt --recipient 'Nissanka De Silva' '/home/nissanka/Documents/Testing for pgp(1).doc'
[root@c83-250-110-112 nissanka]#

------------------------------------------------

I saw the following file on my system now.

Testing for pgp(1).doc.gpg

Did it work?

Yes it worked the Testing for pgp(1).doc.gpg file is the encrypted file created by gpg.
