Name Constraints Extension Default
This default populates a name constraint extension in the certificate request. The
extension is used in CA certificates to indicate a name space within which subject
names or subject alternative names in subsequent certificates in a certification path
or chain should be located.
For general information about this extension, see “nameConstraints” on page 730.
You can define the following constraints with this default:
• Extension Constraint, see “Extension Constraint,” on page 475.
• No Constraints, see “No Constraint,” on page 477.
This default allows you to define 5 locations for both the permitted subtree and the
excluded subtree and specify parameters for each of these location. The parameters
are marked with an
<n>
in the table to distinguish that the parameter is associated
with one of the five possible locations.
decipherOnly

used only for deciphering data. If this bit is set,
keyAgreement
should also be set. Select
