  Hi,

  I do not see any documentations by Microsoft on SQL Server 2012 PREEMPTIVE_OS_CRYPTOPS Wait type, any suggestion on this as what exactly this wait type means and how it impacts the performance?

  Thanks,

  Deepak Prasad Sahu.

  There isn't much available on this one as you found out.
   I did find this explanation on sqlskills waits library:
   PREEMPTIVE_OS_CRYPTOPS

  This other link has some related information which you may find useful:
