The NCrypt API set is not available in kernel mode. What APIs do you
want to use that are not available in the BCrypt API set?

    We want to create persistent keys using key storage functions (like
    NCryptCreatePersistedKey).
    Similar functions are not available in the BCrypt API set.

    Hi ,

    Thanks for the reply.
    Is there any better way to create persistent key from kernel or create a
    key and store it persistent from kernel?

    Thanks,
    S Ramakrishnan
