Get a .pfx/.p12 Safe Bag Attribute

See more PFX/P12 Examples

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. AutoIt

;  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:
Local $bGetPrivateKeyAttr = True
Local $iPrivateKeyIdx = 0
ConsoleWrite("---- private key safebag attributes ----" & @CRLF)
ConsoleWrite($oPfx.GetSafeBagAttr($bGetPrivateKeyAttr,$iPrivateKeyIdx,"localKeyId") & @CRLF)
ConsoleWrite($oPfx.GetSafeBagAttr($bGetPrivateKeyAttr,$iPrivateKeyIdx,"keyContainerName") & @CRLF)
ConsoleWrite($oPfx.GetSafeBagAttr($bGetPrivateKeyAttr,$iPrivateKeyIdx,"storageProvider") & @CRLF)

;  Get the localKeyId attribute for the 1st certificate.
$bGetPrivateKeyAttr = False
ConsoleWrite("---- cert safebag attributes ----" & @CRLF)
ConsoleWrite($oPfx.GetSafeBagAttr($bGetPrivateKeyAttr,0,"localKeyId") & @CRLF)
