Task 1: Verification of Debian DVD ISO image
A link is given that is https://goo.gl/8CNeyc from where all file can get downloaded. It even
contains a long ISO image along with some of its signature-based files including MD5 for
gaining completeness.
 Initially, to bring everything in right place we need to assure that all files must be listed in
the dictionary.
 Secondly, by using GNU Privacy Guard (gpg) that is free, the correctness of signature is
checked and this is also done for MD5 that’s why
 Thirdly, using ID “6294BE9B” public key can be downloaded which is the key ring
server of Debian.
 Both of the checksums files signatures can now be verified.

A line states that “Good signature from "Debian CD signing key<[e-mail]>“
approves Debian DVD image authenticity. We can even use some key fingerprints generated that
is: DF9B 9C49 EAA9 2984 3258 9D76 DA87 E80D 6294 BE9B and is finally compared with
the listed once in the provided link https://www.debian.org/CD/verify, this comparison
determines whether the key fingerprints matches with it.
 Lastly, the content provided in the image of ISO can be verified so as to check the
checksum matches of ISO images with those expected in files of checksums.
