CertFindExtension (Windows Embedded CE 6.0)

  • Article

1/6/2010

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.
