On the download page for OPEN SUSE I see the following under step #4:

Installation DVD:
GPG MD5 and SHA1.

Would some one be good enough to advise what these mean and which one should I choose?

I would like to get all the SUSE images, I know there used to be about 6 cd images.

Thanks

It is just to see if the files have have download are not tempered
If you use k3b as a burning app it calculate the value and you can check if it is the same provided by opensuse

You should include the address of web pages that you are asking about. We shouldn't have to go to Google to find the page.

http://software.opensuse.org/

On that page click on the 'Get It' button.

Now once the frame switches to the download options I don't see what you describe. Instead I see links to download a live CD of OpenSuSE with different configurations. One is a live CD using the KDE desktop in English only. Another is a live CD using the Gnome desktop in English only. Another is a bootable CD image to perform a network installation in English only. The DVD image contains support for all available languages as well as all non proprietary software in their repository.

If you want to run OpenSuSE with English language support you could download and burn any of the live CD images or the network installation bootable CD image.

The answer to your question is that you are seeing links to the image file as well as links to checksum information. The checksum information is used to verify the accuracy of the file that you downloaded. In other words the checksum is used primarily to check for errors.

The MD5 is usually just used to check the accuracy of a download. The GPG and SHA1 are most often used to ensure that you got an official copy rather than some copy from an unauthorized source.

Thanks for your prompt replies.

Which method would you recommend?

md5 seems to be O.K.

md5 is O.K.
But so are they others
But you do not always have a choice some distros only provide you which
one way to check you're download
