Accessing encrypted cdrom using cryptsetup

airkemp · 03-17-2015, 04:33 AM

Hi there

Bit of a Linux noob but I was wondering if anyone could help me access an encrypted cdrom using cryptsetup and luksOpen. I have the password but can’t find how to mount and access it, a lot of examples online start from scratch, creating the encrypted data and burning it. Not sure how far along to start and if i need to create a loop and /or and mapping?

Thanks

Shouldn't be that hard.

Code:

cryptsetup luksOpen /dev/sr0 dvdc
mount /dev/mapper/dvdc /mnt/tmp

Hi metaschima,

Thanks for your reply, i get a "No key available for this passphrase". I'm 100 certain i have entered the correct password. Any Ideas?

Many Thanks

It could be corrupt, try using the luksDump command to get more info:
