Solution: PKA does not work with Delphi7 (General questions)
Hi Kreso,
As usual it is not your fault. There is a bug in D7 that one can't have NULL in a variant. All Keys contain NULL. As you use variants for submitting the PrivateKey setting PKA is unusable in D7.
An update to D7.1 solves this issue completely.
Hope this helps,
Rainer
