IX509PublicKey::Initialize method (certenroll.h)

  • Article

The Initialize method initializes the object from a public key algorithm object identifier (OID) and from byte arrays that contain a public key and the associated parameters, if any. The byte arrays are represented by Unicode-encoded strings.

Syntax

HRESULT Initialize(
  [in] IObjectId    *pObjectId,
  [in] BSTR         strEncodedKey,
  [in] BSTR         strEncodedParameters,
  [in] EncodingType Encoding
);

Parameters

[in] pObjectId

Pointer to an IObjectId interface that represents the algorithm OID.

[in] strEncodedKey

A BSTR variable that contains the public key.

[in] strEncodedParameters

A BSTR variable that contains the parameters associated with the public key. For more information, see the EncodedParameters property.

[in] Encoding

An EncodingType enumeration value that specifies the type of Unicode-encoding applied to the arguments specified in the strEncodedKey and strEncodedParameters parameters. The default value is XCN_CRYPT_STRING_BASE64.

Return value

If the function succeeds, the function returns S_OK.

If the function fails, it returns an HRESULT value that indicates the error. Possible values include, but are not limited to, those in the following table. For a list of common error codes, see Common HRESULT Values.

Return code/value Description
HRESULT_FROM_WIN32(ERROR_ALREADY_INITIALIZED)
 The object has already been initialized.

Remarks

The Initialize method initializes the following property values:
