commit 6302bbd21a79bd2ed59f214d6d042031384b4d12
Author: Dr. Stephen Henson <[email protected]>
Date: Thu May 12 15:24:06 2016 +0100
Correctly check for trailing digest options.
Multiple digest options to the ocsp utility are allowed: e.g. to use
different digests for different certificate IDs. A digest option without
a following certificate is however illegal.
