ServerCertKeyUsageExt Rule
The policy rule named
ServerCertKeyUsageExt
is an instance of the
KeyUsageExt
module. This rule is for setting the appropriate key-usage bits in SSL server
certificates. By default, the rule is configured as follows:
• The rule is enabled.
• The predicate expression (
HTTP_PARAMS.certType==server
) ensures that the
rule is applied only to SSL server certificate requests.
• The extension is marked noncritical (to comply with the PKIX
recommendation).
• The server is configured to set
digitalSignature
,
nonRepudiation
,
keyEncipherment
, and
dataEncipherment
bits in SSL server certificates.
Notice that the key-usage bits specified in the default policy rule match the bits
specified in the enrollment form (
ManServerEnroll.html
) for requesting SSL
server certificates (see Figure 4-15).
