IInternetSecurityManagerEx2::GetSecurityIdEx2 method
Gets the security identifier of the specified URL.
Syntax
HRESULT GetSecurityIdEx2(
[in] IUri *pUri,
[out] BYTE *pbSecurityId,
[in, out] DWORD *pcbSecurityId,
[in] DWORD_PTR dwReserved
);
Parameters
pUri [in]
A pointer to an IUri interface that specifies the URL.pbSecurityId [out]
A buffer that specifies the scheme, domain name, and zone associated with the URL.pcbSecurityId [in, out]
A DWORD that specifies the size of the buffer being passed in.dwReserved [in]
A LPCWSTR that specifies the domain suffix to use as the security identifier. If set to NULL, the full domain name is used.
Return value
Returns S_OK if successful, or E_INVALIDARG if pbSecurityId or pUri is set to NULL, or if pUri does not contain a valid URL.
Remarks
IInternetSecurityManagerEx2::GetSecurityIdEx2 was introduced in Windows Internet Explorer 7.
IInternetSecurityManagerEx2::GetSecurityIdEx2 is identical to GetSecurityId except that it takes its URL from an IUri object.
A security identifier contains the scheme, domain, and zone information in the following format.
<scheme>:<domain>+<zone>
If the allocated buffer is too small, IInternetSecurityManagerEx2::GetSecurityIdEx2 returns an HRESULT derived from the Microsoft Win32 error code ERROR_INSUFFICIENT_BUFFER and sets the pcbSecurityId parameter to the required size in bytes. Upon a successful return, pcbSecurityId contains the actual size of the data stored in the buffer.
Security Warning: Incorrect implementation of this method can compromise the security of your application. A custom implementation of GetSecurityId should generate IDs only for hosts that cannot be handled by the default implementation. For all other hosts, this method should return INET_E_DEFAULT_ACTION. An attempt to duplicate the default implementation can result in the creation of IDs that are less secure and are susceptible to a spoofing attack.
