SafeCRLHandleContext Class

SafeCRLHandleContext provides a SafeHandle class for an X509CRL2 certificate revocation list context as stored in its Handle property. This can be used instead of the raw IntPtr to avoid races with the garbage collector, ensuring that the X509Certificate object is not cleaned up from underneath you while you are still using the handle pointer.

This safe handle type represents a native CRL_CONTEXT.

A SafeCRLHandleContext for an X509CRL2 can be obtained by calling the GetSafeContext extension method.
