Hello,

Iam collection informations for a small project I want to do. So forgive
me if I ask stupid questions.

For this project I need to use a user mode library (cryptlib). But it is
generally not recommended to use a usermode library in a kernel mode
driver, as I read. So I try to figure out how much work I have to expect
to port this library. Seven years ago there was already a kernel mode
version of this library, so I think it must be possible to do it. But it
was not done by the src code autor.
Iam unable to contact the autor of the kernel mode version.

The cryptlib library uses function from the crt, like malloc() and
memset(). Has anyone already some experience on porting to kernel mode?
And/Or can point me to some informations?

Is it true that kernel mode driver should only use kernel functions like
Zw... and Rtl... and so on? But why comes the Windows DDK already with
the crt header files? (X:\WINDDK\2600\inc\crt)

Thank you for your efforts!
