Delphi 7 access Windows X509 Certificate Store

Question

My question is pretty simple: is there a simple way to access Windows X509 Certificate Store using Delphi 7?

Before asking this question I have googled, but have not found any useful info.

Answer 1

the easiest way is to use capicom, hitting the win capi api directly is painful.

once you've registered the com object and created your typelib unit from it..

open the appropriate store, and from there use the certificates() method..

  var
    store: TStore;
    certificates: ICertificates;
    certificate: ICertificate2

  store := TStore.Create(nil);
  store.Open(CAPICOM_CURRENT_USER_STORE, 'My', CAPICOM_STORE_OPEN_MAXIMUM_ALLOWED or CAPICOM_STORE_OPEN_INCLUDE_ARCHIVED or CAPICOM_STORE_OPEN_EXISTING_ONLY);

  certificates := store.Certificates;
  for i := 1 to certificates.count do
  begin
    certificate := IInterface(certificates.Item[i]) as ICertificate2;
    // work with the cert
  end;

  store.close();
  store.Free;

capicom reference is at http://msdn.microsoft.com/en-us/library/ms995332.aspx

if you're ok with spending money, i've heard good things about PKIBlackbox from eldos.

Isn't that what you are looking for? Cryptography Reference

Or do you search an API Wrapper?
