Delphi ActiveX Requires Chilkat v11.0.0+

Load Certificate from PFX (PKCS#12)

See more Certificates Examples

Loads a digital certificate (and private key, if available) from a PFX file.(also known as PKCS#12) Delphi ActiveX

var
success: Integer;
cert: TChilkatCert;
pfxFilename: WideString;
pfxPassword: WideString;
privKey: TPrivateKey;

//  Load from the PFX file
pfxFilename := '/Users/chilkat/testData/pfx/chilkat_ssl_pwd_is_test.pfx';
pfxPassword := 'test';

//  A PFX typically contains certificates in the chain of authentication.
//  The Chilkat cert object will choose the certificate w/
//  private key farthest from the root authority cert.
//  To access all the certificates in a PFX, use the 
//  Chilkat certificate store object instead.
success := cert.LoadPfxFile(pfxFilename,pfxPassword);

  begin
    Memo1.Lines.Add(cert.LastErrorText);

//  then get the private key...

//  DN = "Distinguished Name"

success := cert.GetPrivateKey(privKey.ControlInterface);
if (success = 0) then
  begin

    Exit;
  end;

//  The private key object may be used in any Chilkat methods
//  (in other objects/classes) that expect a private key argument.

//  In this case, save the private key to a PKCS8 Encrypted PEM format file:
pemPassword := 'secret';
