All source files in lib/hcrypto should be built the same way.
Since this source directory is dependent on libroken then all source
files must be built using the roken.h declarations and included headers.
Also, there is no config.h in the local directory so angle brackets
include of quotes should be used.
Finally, because roken.h includes stdio.h, stdlib.h, stdarg.h, limits.h,
strings.h, sys/types.h, etc., do not include them separately.
Start all source files with
#include <config.h>
#include <roken.h>

_hc_CryptProvider() returns a global handle to a Win32 Crypt Provider.
If the global handle is NULL, then a handle is allocated. Unfortunately,
due to a coding mistake the global handle variable, g_cryptprovider, was
never set and a new handle was allocated with each call.
Refactor the function to ensure that the global handle is the value
that is returned. Use NULL instead of 0 for pointer assignment.

Heimdal can be executed in environments in which the user
account profile is not loaded. In such environments it is
not possible to use PROV_RSA_FULL as it stores required
data within the profile. Instead, fallback to PROV_RNG which
does not store data within the profile and can be used to access
secure random number generator routines.
