A CRL (certificate revocation list) is used when a particular
|
|
150
|
key is compromised but when the overall PKI is still intact.<br>
|
|
151
|
<br>
|
|
152
|
Suppose you had a PKI consisting of a CA, root certificate, and
|
|
153
|
a number of client certificates. Suppose a laptop computer
|
|
154
|
containing a client key and certificate was stolen. By adding the
|
|
155
|
stolen certificate to the CRL file, you could reject any connection
|
|
156
|
which attempts to use it, while preserving the overall
|
|
157
|
integrity of the PKI.<br>
|
|
158
|
<br>
|
|
159
|
The only time when it would be necessary to rebuild the entire
|
|
160
|
PKI from scratch would be if the root certificate key itself was
|
|
161
|
compromised.
