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. SQL Server

    --  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:
    DECLARE @getPrivateKeyAttr int
    SELECT @getPrivateKeyAttr = 1
    DECLARE @privateKeyIdx int
    SELECT @privateKeyIdx = 0

    PRINT '---- private key safebag attributes ----'
    EXEC sp_OAMethod @pfx, 'GetSafeBagAttr', @sTmp0 OUT, @getPrivateKeyAttr, @privateKeyIdx, 'localKeyId'
    PRINT @sTmp0
    EXEC sp_OAMethod @pfx, 'GetSafeBagAttr', @sTmp0 OUT, @getPrivateKeyAttr, @privateKeyIdx, 'keyContainerName'
    PRINT @sTmp0
    EXEC sp_OAMethod @pfx, 'GetSafeBagAttr', @sTmp0 OUT, @getPrivateKeyAttr, @privateKeyIdx, 'storageProvider'
    PRINT @sTmp0

    --  Get the localKeyId attribute for the 1st certificate.
    SELECT @getPrivateKeyAttr = 0

    PRINT '---- cert safebag attributes ----'
    EXEC sp_OAMethod @pfx, 'GetSafeBagAttr', @sTmp0 OUT, @getPrivateKeyAttr, 0, 'localKeyId'
    PRINT @sTmp0

    EXEC @hr = sp_OADestroy @pfx
    EXEC @hr = sp_OADestroy @json
