So here's my dilemma:
i ran these 3 commands in terminal, one at a time, to check the hashes of a burnt dvd:
dd if=/dev/cdrom bs=1 count='size' | md5sum
dd if=/dev/cdrom bs=1 count='size' | sha1sum
dd if=/dev/cdrom bs=1 count='size' | sha256sum
The thing is, the md5 of the burnt dvd was the same as the ISO image md5. However the sah1 and sha256 were completely different!
Questions:
Are the above mentioned commands the correct ones for getting those 3 hashes?
How is it possible for the md5 to match, but the sha1 and sha256 not to? Why is that? And how can i fix it?
Thank you for the upcoming support!
