Hello,
I am trying to add support for HMAC-SHA256 using black keys. I have modified the CAAM code to do this and it runs without error, but it produces the wrong output. To debug this I would like to be able to duplicate what the CAAM does. I am generating a CAAM key with `caam-keygen create black_key ecb -t abcdef0123456789`. I was expecting that the generated file would contain abcdef0123456789 encrypted with the contents of /sys/kernel/debug/30900000.crypto/ctl/kek, but this does not seem to be the case. Do you know how the black key is created?
Thanks,
Gareth |
