The GenExtKeyUsage tool has the following syntax:
GenExtKeyUsage [true|false] OID ...
| Option | Description |
|---|---|
| true | false | Sets the criticality. true means the extension is critical; false means it is not critical. The criticality value is used during the certificate validation process. If an extension is marked as critical, then the path validation software must be capable of interpreting that extension. |
| OID | The OID numbers that represent each certificate type selected for the certificate. |
Table 19.1.
For more information on the OIDs that can be used for each certificate type, refer to appendix A, "Certificate and CRL Extensions," in the Certificate System Administration Guide.
