Do I have the necessary ciphers to unlock my LUKS device? Posted: 04 May 2019 05:41 PM PDT Hi there, I have a LUKS block device that I can no longer unlock with my key file. I lost access after I migrated a server from Ubuntu Server LTS to Proxmox. I'm trying to determine if my system supports the necessary combination of ciphers, modes, hashes, and key sizes to unlock the device. Unfortunately, I'm not knowledgeable enough about ciphers to piece together this information. The combination used on the device is aes-xts-plain64 sha1. I don't see that exact combination in my installed ciphers, but again, I don't fully understand what I'm looking at. I appreciate any thoughts you all may have. ​ The LUKS header dump showing which cipher was used to encrypt the device: https://gist.github.com/matthew02/cbfb17869dabf6d7f39dae83a34ca36b ​ The list of installed ciphers with additional details. https://gist.github.com/matthew02/abb88475392933f837570d0479e29c71 ​ Edit: It seems I have already been downvoted right out of the cage. I did check with the mods before posting this to make sure it wasn't inappropriate for this sub. I got the okay, but if it's generally considered that I'm in the wrong place, let me know and I'll delete the post. submitted by /u/AmericanNinja02 [link] [comments]
