CRL Error codes
This method saves the CRL to the provided memory location of the given size.
If the buffer is too small (or empty),
Size parameter is set to the size which will be enough to hold the whole data.
The CRL is saved in DER format.
Use overloaded method without Certificate parameter to save only a *copy* of the loaded/generated CRL (without re-signing it).
