Chapter 18. GenExtKeyUsage (Adding the Key Usage Extension to a Request)
The
GenExtKeyUsage tool creates a base-64 encoded blob that adds ExtendedKeyUsage (OID 2.5.29.37) to the certificate. This blob is pasted into the certificate approval page when the certificate is created.
18.1. Syntax
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. |
