Feature changed by: Mario Goppold (mgoppold) Feature #302628, revision 29 Title: Access to encrypted devices/partitons by dongle openSUSE-11.0: Rejected by Stephan Kulow (coolo) reject date: 2008-03-31 10:53:14 reject reason: too late - and still lacking a real concept behind the full story. Priority Requester: Desirable openSUSE-11.1: Rejected by Stephan Kulow (coolo) reject date: 2008-08-07 16:27:08 reject reason: out of resources. Priority Requester: Desirable openSUSE-11.2: Evaluation Priority Requester: Desirable Requested by: Stefan Fent (sfent) Description: Think of the following scenario: You store your files on an encrypted partition and if you want to access them you just insert your USB stick, flash card or whatever and gain access to your files. Another thought would be to encrypt the whole system and the only possibilty to access it is via dongle. Relations: - FATE#301352: Filesystem encryption using Smartcard certificate (feature/id: 301352) Discussion: #1: Gerald Pfeifer (geraldpfeifer) (2007-10-05 23:04:19) Michele (desktop) / Matthias (storage) what do you think about this? #2: Michael Löffler (michl19) (2008-01-02 18:27:26) Nice to have but I miss a business case. #3: Stephan Kulow (coolo) (2008-01-07 14:42:28) (reply to #2) the business case of such a feature only works if you have a company to sell those dongle sticks I'd say. And those dongle vendors prefer custom boot loaders from those I know. So I don't think a solution with a stick that can be easily copied by dd is preferrable and I would rather reject this. #4: Guy Lunardi (glunardi) (2008-01-18 19:46:42) It's my understanding that Chris' work would allow for this to happen. This would be very neat indeed, we have discussed this with several customers who expressed interest. Using a simple USB key would be one inexpensive way to make this work. One alternative that a customer asked was to have the ability to unlock the data using certificates strored within a smart card. #7: Stephan Kulow (coolo) (2008-06-27 11:23:16) (reply to #4) Chris work? I fail to see the context. #9: Guy Lunardi (glunardi) (2008-07-02 15:27:37) (reply to #7) I do believe that Chris' work would be good for us to leverage however I do not know the details and could be wrong since it has been a few months now since we last talked about this. Chris, would you be able to assist me with provide insights on ways we could address this? #11: Chris Rivera (chrismrivera) (2008-07-06 23:52:49) (reply to #9) If you setup an encrypted home directory with cryptconfig it defaults to creating an encrypted container and a key file. The key file can reside anywhere, including removable media. If you use removable media you need to setup an fstab entry using the device label or device UUID to ensure that the dongle gets mounted automatically and the key file is in the right location. #12: Stephan Kulow (coolo) (2008-08-07 16:26:44) (reply to #11) ok, just talked about with Chris about this feature. We have no resources for yast work any more and the work required seem to be this: "so it would just mean moving the .key file to the media, changing the . key file location in pam_mount.conf, and adding an fstab entry" (quoting Chris). So this would be either put in a README or we wait for SPx. #13: Stephan Kulow (coolo) (2009-03-04 11:39:07) (reply to #12) any objection against opening this to openSUSE.org? #14: Marcus Meissner (msmeissn) (2009-03-04 11:40:59) (reply to #13) no, done #5: Stephan Kulow (coolo) (2008-03-31 10:52:41) I still have no clear picture of what cryptfs setups we're going to support - there are various fate entries about it: e,g, 302981 and 301352. So I would like PM to sort this out - and I personally think it's too late for 11.0. #6: Matthias Eckermann (mge1512) (2008-04-01 01:35:14) In an ideal world we would support: * TPM (incl. fingerprint readers etc.) * Smart Cards * simple devices with key on (USB sticks, memory cards) * passphrase (as today) * (optional) integration with a directory (LDAP, eDirectory, ...) + #15: Mario Goppold (mgoppold) (2009-03-29 22:26:03) + Hi, because I just need to unlook my root partition via USB stick I + have build an rpm for it: http://download.opensuse.org/repositories/home:/mgoppold/openSUSE_11.1/x86_6... + _SVNr46_luks_key-64.1.x86_64.rpm The main changes are in + /lib/mkinitrd/scripts/{setup,boot}-luks.sh and the new + /etc/sysconfig/initrd.luks_key. The LUKS-Keyfile should on an Labled or + UUIDed USB-Stick. You can unlook all partitions with a master key or + define a separate for every luks_device. The approach is certainly not + the best but there is no keyscript in /etc/crypttab jet (why not?). -- openSUSE Feature: https://features.opensuse.org/302628
