CAPICOM use for signature in Delphi

Asked

I’m using the capicom.dll on Delphi to perform the signature on files (planned in .pdf). I’ve been able to read the certificates My of the area CAPICOM_CURRENT_USER_STORE.

But I have the following problem in IF down below:

if (cert.HasPrivateKey) And (cert.ValidFromDate <= Now) And (cert.ValidToDate >= Now) then
  begin
  { assinar um documento }
  end;i

The problem is in (cert.HasPrivateKey). He is always returning Inaccessible value in the watch. Can anyone give me a hand? Note: If this method is outdated, please let me know!

  • Inaccessible value is not a problem, he is informing you that you can not show a value, of course, HasPrivateKey is a method and not a property.

  • in the example I’m following, he takes that test... it would be wrong to take the test then?

  • No, it’s not, I’m saying he’s not a problem.

  • Friend, do you know about this routine? In my source it uses this validation (the whole if). Obs: I have 2 certificates on my machine
