/**
|
|
* Represent the OCSP NoCheck Extension from RFC2560.
|
|
* <p>
|
|
* A CA may specify that an OCSP client can trust a responder for the
|
|
* lifetime of the responder's certificate. The CA does so by including
|
|
* the extension id-pkix-ocsp-nocheck. This SHOULD be a non-critical
|
|
* extension. The value of the extension should be NULL. CAs issuing
|
|
* such a certificate should realize that a compromise of the
|
|
* responder's key is as serious as the compromise of a CA key used to
|
|
* sign CRLs, at least for the validity period of this certificate. CA's
|
|
* may choose to issue this type of certificate with a very short
|
|
* lifetime and renew it frequently.
