-=item B<-verbose>
+=item B<-ignore_critical>
 
-print extra information about the operations being performed.
+Normally if an unhandled critical extension is present which is not
+supported by OpenSSL the certificate is rejected (as required by RFC5280).
+If this option is set critical extensions are ignored.
+
+=item B<-inhibit_any>
+
+Set policy variable inhibit-any-policy (see RFC5280).
+
+=item B<-inhibit_map>
+
+Set policy variable inhibit-policy-mapping (see RFC5280).
 
 =item B<-issuer_checks>
 
-print out diagnostics relating to searches for the issuer certificate
-of the current certificate. This shows why each candidate issuer
-certificate was rejected. However the presence of rejection messages
-does not itself imply that anything is wrong: during the normal
-verify process several rejections may take place.

-=item B<-check_ss_sig>
+=item B<-partial_chain>
 
-Verify the signature on the self-signed root CA. This is disabled by default
-because it doesn't add any security.
+Allow partial certificate chain if at least one certificate is in trusted store.
+
+=item B<-policy arg>
+
+Enable policy processing and add B<arg> to the user-initial-policy-set (see
+RFC5280). The policy B<arg> can be an object name an OID in numeric form.
+This argument can appear more than once.
+
+=item B<-policy_check>
+
+Enables certificate policy processing.
+
+=item B<-policy_print>
+
+Print out diagnostics related to policy processing.
+
+=item B<-purpose purpose>
+
+The intended use for the certificate. If this option is not specified,
+B<verify> will not consider certificate purpose during chain verification.
