Task 1
Debian DVD ISO image’s verification process
From the link https://goo.gl/8CNeyc, the required data has been downloaded and ISO image
has been checked for their completeness by comparing the signatures as follows.
 List and save all the file in the directory at the correct place
 For the MD5, correct signature must be verified using the free tool named as GNU
Privacy Guard
ID= 6294BE9B has been extracted from running the above command where public
key is not available. The reason for non-availability is that the command runs for the
first time. To retrieve the public keys, following steps are done.
 Now from the server of Debian Key, the public key can be downloaded using the ID
“6294BE9B”

 For the checksum files, there will be verification of their signatures
The confirmation of the authenticity is stated by the appearance of the statement as
“Good signature from "Debian CD signing key <[e-mail]>”. The
comparison with the list given in https://www.debian.org/CD/verify is done with the
help of generated fingerprint key as DF9B 9C49 EAA9 2984 3258 9D76 DA87 E80D
6294 BE9B.
