Hello,
We are not adding user-space interface.
We just need to algo definitions which are in sync between user space,
IMA/EVM and kernel module signing.
Module signing perl script uses hard coded values. We want to improve
it export them to user space.
But please give us a hint, what crypto user-space API helps for us?
Thanks!
Dmitry
