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. PowerBuilder

//  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:
li_GetPrivateKeyAttr = 1
li_PrivateKeyIdx = 0
Write-Debug "---- private key safebag attributes ----"
Write-Debug loo_Pfx.GetSafeBagAttr(li_GetPrivateKeyAttr,li_PrivateKeyIdx,"localKeyId")
Write-Debug loo_Pfx.GetSafeBagAttr(li_GetPrivateKeyAttr,li_PrivateKeyIdx,"keyContainerName")
Write-Debug loo_Pfx.GetSafeBagAttr(li_GetPrivateKeyAttr,li_PrivateKeyIdx,"storageProvider")

//  Get the localKeyId attribute for the 1st certificate.
li_GetPrivateKeyAttr = 0
Write-Debug "---- cert safebag attributes ----"
Write-Debug loo_Pfx.GetSafeBagAttr(li_GetPrivateKeyAttr,0,"localKeyId")
