+/**
+ * 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 realized 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.
+ * <pre>
+ * id-pkix-ocsp-nocheck OBJECT IDENTIFIER ::= { id-pkix-ocsp 5 }
