- specification and has the following definition:\r
-\r
- @param dwLength The length of the entire certificate,\r
- including the length of the header, in\r
- bytes.\r
-\r
- @param wRevision The revision level of the WIN_CERTIFICATE\r
- structure. The current revision level is\r
- 0x0200.\r
-\r
- @param wCertificateType The certificate type. See\r
- WIN_CERT_TYPE_xxx for the UEFI\r
- certificate types. The UEFI\r
- specification reserves the range of\r
- certificate type values from 0x0EF0\r
- to 0x0EFF.\r
-\r
- @param bCertificate The actual certificate. The format of\r
- the certificate depends on\r
- wCertificateType. The format of the UEFI\r
