RE: [Cdsa-discuss] Certificate Revocation List-Doubt

[Bowler, D. <dav...@in...>]

There are two issues with the way you're doing things, both relating to
the overall size of the serial number.

field_ptr[0].FieldValue.Length = sizeof(uint8);
should be something like:
field_ptr[0].FieldValue.Length = sizeof(uint32);

and

*(field_ptr[0].FieldValue.Data) = (uint8)(new_serial);
could be something like
memcpy((field_ptr[0].FieldValue.Data),
       &(new_serial),
       sizeof(uint32));

There are obviously many ways to write what you're trying to write, but
the important thing is to make sure you're moving the full serial number
value into the data field and put the correct length into the length
field.
