Description Stefan Briesenick (RETIRED) gentoo-dev 2011-03-03 15:00:32 UTC
when using debian/ubuntu, you can use so called keyscripts to return the actual key, which is then piped to cryptsetup. The 'key' is then just a paramter for the script.



will do basically this:

$keyscript "$key" | cryptsetup --key-file=- luksOpen ...

this is extremely handy, if you don't have a real keyfile somewhere, but want to calculate it somehow (the decrypt_derived script gets the key from an already unlocked LUKS device via dmsetup table).

But the current /etc/init.d/dmcrypt init-script don't support this. You can only specify a real keyfile. It would be nice to add 'keyscript' support. Shouldn't be a problem. Just add a new keyword 'keyscript', and if specified, use the method described above. Don't forget to use "$key" as a parameter for $keyscript.


Reproducible: Always

I'm in the systemd camp these days, so this issues has sort of lost relevance to me :/
