Hi there.
I was creating a plugin for signature validating. The problem is that signature uses third party digest algorithm "GOST34311". I think Adobe simply does not recognize such algorithm. I tried to catch the exception in this function:
void DSEngine::sigValidate( PSSigValidateParams params );
but it doesn't even get there, exception is thrown before.
So, how can I get algorithm name and handle any custom digest algorithm? Please, give some approach.
Thanks in advance!

Custom digest algorithms aren’t supported by either PDF or Acrobat – such a file would not be valid.
