CertFindExtension
This function finds the first extension in the CERT_EXTENSION array, as identified by its object identifier(OID). This function can be used in the processing of a decoded certificate. A CERT_INFO structure is derived from a decoded certificate. The rgExtension array is retrieved from that structure and passed to this function in the rgExtension parameter. This function determines whether a particular extension is in the array, and if so, returns a pointer to it.
PCERT_EXTENSION WINAPI CertFindExtension(
LPCSTR pszObjId,

);
Parameters
- pszObjId
[in] Pointer to the OID to use in the search. - cExtensions
[in] Number of extensions in the rgExtensions array. - rgExtensions
[in] Array of CERT_EXTENSION structures.
Return Values
