I'm trying to use dm-crypt on my Raspberry Pi 2 with Raspbian (jessie) to open a trueCrypt volume, but i get
Required kernel crypto interface not available. Ensure you have algif_skcipher kernel module loaded.
My research has yielded that algif_skcipher should be available since
2.6.38, but my kernel version is
3.18.11-v7+ (according to
uname). Why isn't the module available and, more importantly how can I fix this?
