(Delphi ActiveX) Get a .pfx/.p12 Safe Bag Attribute

Demonstrates how to get the value of a private key or certificate safe bag attribute. Safe bag attributes are associated with a key or certificate. They are attributes stored in the .p12/.pfx alongside a key or certificate.

Note: This example requires Chilkat v9.5.0.83 or greater.

// Generate Parsing Code from JSON

// In the above JSON, we can see the .pfx contains one private key (a pkcs8ShroudedKeyBag) and two certificates (each in a certBag).
// The certificates in a .pfx/.p12 are typicaly a single certificate with associated private key, along with the other certificates
// in the chain of authentication.

// We can see that the private key has 3 safebag attributes: localKeyId, keyContainerName, and msStorageProvider.
// The certificate associated with the private key contains one safebag attribute: localKeyId.
// Notice the localKeyId is the same.  The localKeyId helps associate the private key that corresponds to the given certificate.

// Let's demonstrate the GetSafeBagAttr method:

// Get each of the private key safebag attributes:
getPrivateKeyAttr := 1;
privateKeyIdx := 0;
Memo1.Lines.Add('---- private key safebag attributes ----');
Memo1.Lines.Add(pfx.GetSafeBagAttr(getPrivateKeyAttr,privateKeyIdx,'localKeyId'));
Memo1.Lines.Add(pfx.GetSafeBagAttr(getPrivateKeyAttr,privateKeyIdx,'keyContainerName'));
Memo1.Lines.Add(pfx.GetSafeBagAttr(getPrivateKeyAttr,privateKeyIdx,'storageProvider'));

// Get the localKeyId attribute for the 1st certificate.
getPrivateKeyAttr := 0;
Memo1.Lines.Add('---- cert safebag attributes ----');
Memo1.Lines.Add(pfx.GetSafeBagAttr(getPrivateKeyAttr,0,'localKeyId'));
end;
