Delphi DLL Requires Chilkat v9.5.0.49+

Load P7B and Iterate Certificates

See more PEM Examples

Demonstrates how to load a .p7b containing one or more certificates access each of them. Delphi DLL

var
success: Boolean;
pem: HCkPem;
numCerts: Integer;
i: Integer;
cert: HCkCert;

begin
success := False;

//  This example assumes the Chilkat API to have been previously unlocked.
//  See Global Unlock Sample for sample code.

success := False;

//  The Chilkat PEM class requires the bundle to be unlocked, as shown above.
pem := CkPem_Create();

//  Load the .p7b from a file.
success := CkPem_LoadP7bFile(pem,'../myCertFiles/myP7b.p7b');
if (success <> True) then
  begin
    Memo1.Lines.Add(CkPem__lastErrorText(pem));
    Exit;
  end;

//  Note: If the app already has the p7b loaded in memory, the LoadP7b method
//  may be called instead.  (see the online reference documentation)

//  Iterate over the certificates.
numCerts := CkPem_getNumCerts(pem);
i := 0;

while i < numCerts do
  begin

    cert := CkPem_GetCert(pem,i);

    CkCert_Dispose(cert);

    i := i + 1;
