The InitializeDecode method initializes the object from a Distinguished Encoding Rules (DER) encoded byte array that contains the attribute value. The byte array is represented by a Unicode-encoded string.
An EncodingType enumeration value that specifies the type of Unicode encoding applied to the input string.
A BSTR variable that contains the DER-encoded attribute.
If the function succeeds, the function returns S_OK.
If the function fails, it returns an HRESULT value that indicates the error. For a list of common error codes, see Common HRESULT Values.
The object identifier (OID) for this attribute is XCN_OID_REQUEST_CLIENT_INFO (1.3.6.1.4.1.311.21.20). For more information, see CERTENROLL_OBJECTID.
You can use this method if you have a DER-encoded Abstract Syntax Notation One (ASN.1) object that contains the attribute value. You must supply the DER-encoded object in a Unicode encoded string. For more information, see the IBinaryConverter interface.
You must call either InitializeEncode or InitializeDecode before you can use an IX509AttributeClientId object. The two methods complement each other. The InitializeEncode method enables you to construct an encoded ASN.1 structure from raw data, and the InitializeDecode method enables you to initialize raw data from an encoded ASN.1 structure. You can call the following properties to retrieve the raw data:
