GPGP for Linux

Gins · 08-19-2006, 05:07 PM

Thanks Happy Tux

I can't fathom out what you have written.

Here you needed --output in the line the easiest way to remember this is in the vast majority of options if it is a letter then -a say if a word then --all you need the -- for a word option.
[ I don't know the meaning of the above sentence.]

What is BTW?

I looked at Google about the kgpg. It is a graphical version of the GPG.
Do I need this? I have the command line version. Is it a differnt product?
Does it overwrite the command line version?
-----------------------------------------------------

Tinkster insists that I must read the The Frindly Manual.
As far as I am concerned, it is an Unfrindly Manual.
They don't know how to write in a simple manner.

When an option is a full word/combination of words you need a -- in front of it in the vast majority of the cases if its a letter then only a - is needed.

Short for by the way if you install the dict and dictd packages along with the on-line dictionary dictionary then you could use at the command line.

Code:

dict BTW

Not needed if you want to do it on command line all the time. It is a KDE front end for gpg and is used in place of the command line version the command line version will still be available for use if it is installed.

That is a common complaint with man pages especially the ones where they never give clear examples of how the command should be used some are better than others. Even after all these years of using linux I look at them sometimes and think just what the hell is that supposed to mean.

As far as I'm concerned it doesn't seem to make much of
a difference whether it's spelt out in plain or inside a man-
page .... :}

You didn't even manage the transition from

Code:

 gpg -d test.gpg  --output newfile.txt

to the same thing with just a different name for the output
file - I mean, how sad is that.

And you ignored the option

Code:

gpg test.gpg

which would have created a file called test.asc for
you rather than having to specify a name explicitly.

Cheers,
Tink

I thank Happy Tux and Tinkster for their comments. Your comments are useful to me.

In this decryption process, I never used my private key. It is my understanding that the private key is a must in the process of decryption.
Could you please comment on this?

By the way, I have been telling here that the man pages are not written in an user frindly manner.This is purely the my point of view.

Some websites are written in an excellent fashion. Please look at the following website. It is an excellent website for people who are intereted in UNIX. You can never ever draw a parallel with man pages and thie website.

Tinkster · 08-20-2006, 01:05 PM

Of course you used your private key. You were prompted to give your
pass-phrase. The information WHICH key can be used to decrypt a file
comes INSIDE the encrypted file.

Cheers,
Tink

Gins · 08-20-2006, 01:33 PM

Do you mean the passphrase is someway combined to the private key?

It seems you don't have a public key. I searched invain for Tinkster.

The passphrase is used when generating the key along with the key generating method chosen this combines to produce the public/private keys, when decrypting gpg checks in the keyring for the private key which was used to encrypt the file (this information is identified/contained in the encrypted file as well as the file contents) then asks for the passphrase if you have the right passphrase it decrypts the file if not it fails and the file remains encrypted.

Gins · 08-20-2006, 02:19 PM

Thanks Happy Tux for taking time to reply me again.

I would like to download and install kgpg. Please look at the following:
-----------------------------------------------
Downloading Kgpg:
KGpg 1.1 is in the kdeutils package of KDE 3.2. You can download it from kde.org
Old version(source file): kgpg-1.0.0.tar.gz (signature)

http://developer.kde.org/~kgpg/download.html
------------------------------------------------

I would like to download and install the above 'kgpg-1.0.0.tar.gz' file.

Are you sure it will not create problems for me?
Will it corrupt the existing gpg program?
Is it the same program?
Do I have to crate new keys or my present keys will work?

HappyTux · 08-20-2006, 02:35 PM

Your running Mandrake right? If so you should be able to get kgpg using its package manager no need to download from the KDE site. All Kgpg does is give you a KDE front end program that uses the gpg already on the system no need for new keys it will find your existing keyring just fine and use it for what it needs to do its job.

Gins · 08-20-2006, 02:42 PM

I don't think it is there. I will look at the package manager. Not right now. I must sleep now as I have to leave early in the morning to go to work.

I know life make easy if I could use the package manger to install the programs.

Gins · 08-21-2006, 02:31 PM

Happy Tux

I looked at the package manager. I found the following files. Could you please tell me which one to install?

There is no kgpg in the packae manager. Shall I download and install the following file?

http://developer.kde.org/~kgpg/download.html

HappyTux · 08-21-2006, 03:21 PM

The page you link too has the kgpg in the kdeutils so check to see if Mandrake has that for a package it may not be separate. If not available then you can always install the gpgp-0.4-10mdk and use the gnome front end version it will work under KDE.

Gins · 08-22-2006, 04:02 PM

Thanks Happy Tux for the reply.
I am a bit busy at the moment and it is very difficult to find time to work with computers. I will contact you soon.

Gins · 09-03-2006, 01:59 PM

I need help again. I just want to check some files or rather CDs which I downloaded.
They gave me the following key.

I used the vi command and saved the file. I used the following:

So the name of the file is ' mandriva-free-2007-tyr-CD.x86_64.md5.asc '

I created or rather placed the file inside the '/usr/local/bin' folder. Because it contains all the gpg stuff.

[root@c83-250-110-112 bin]# vi mandriva-free-2007-tyr-CD.x86_64.md5.asc

However, the following import command didn't work.

What is the problem?

That would not be getting the Mandriva key on this page is the key you need I think then you need to.

Code:

gpg: depth: 1  valid:   1  signed:   0  trust: 1-, 0q, 0n, 0m, 0f, 0u

To import then I think that you need to run the gpg --verify command on the mandriva-free-2007-tyr-CD.x86_64.asc file itself (whatever its name) not the signed md5sum file like you tried to import.

Edit: When sending me a message make it in plain text I have no windows to read a .doc file with.
