the OCSP response signing certificate. Some responders omit the actual signer's

certificate in such cases.
=item B<-trust_other>
the certificates specified by the B<-verify_certs> option should be explicitly
trusted and no additional checks will be performed on them. This is useful
when the complete reponder certificate chain is not available or trusting a
root CA is not appropriate.

don't attempt to verify the OCSP response signature or the nonce values. This

signers certificate. With this option the signers certificate must be specified
with either the B<-verify_certs> or B<-VAfile> options.
=item B<-no_sig_verify>
don't check the signature on the OCSP response. Since this option tolerates invalid
signatures on OCSP respondes it will normally only be used for testing purposes.
=item B<-no_cert_verify>
don't verify the OCSP reponse signers certificate at all. Since this option allows
the OCSP response to be signed by any certificate it should only be used for
testing purposes.
=item B<-no_chain>
do not use certificates in the response as additional untrusted CA
certificates.
=item B<-no_cert_checks>
don't perform any additional checks on the OCSP response signers certificate.
That is do not make any checks to see if the signers certificate is authorised
to provide the neccessary status information: as a result this option should
only be used for testing purposes.
=item B<-validity_period nsec>, B<-status_age age>
these options specify the range of times, in seconds, which will be tolerated
in an OCSP response. Each certificate status response includes a B<notBefore> time and
an optional B<notAfter> time. The current time should fall between these two values, but
the interval between the two times may be only a few seconds. In practice the OCSP
responder and clients clocks may not be precisely synchronised and so such a check
may fail. To avoid this the B<-validity_period> option can be used to specify an
acceptable error range in seconds, the default value is 5 minutes.
If the B<notAfter> time is omitted from a response then this means that new status
information is immediately available. In this case the age of the B<notBefore> field
is checked to see it is not older than B<age> seconds old. By default this additional
check is not performed.

This utility is incomplete. It currently does not completely check the OCSP
response's: it does not check the validity dates for example.
The B<host> and B<path> options may well go away and be replaced by a B<url>
option or an option to determine the URI based on certificate extensions.
SSL OCSP responders using https URLs cannot currently be queried.
