You can test the configuration and setup of Nexus OCSP Responder by using the bundled OCSP client. It is named ocsp_client.bat on Windows and ocsp_client on the available Linux distributions. The OCSP client is located in the /bin directory relative to the installation root.
The basic usage of the bundled OCSP client is as follows:
The certificate to use for TLS client authentication. Replace <certificate> with either the filename of the PKCS12 encoded token or unique part of subject DN of certificates in PKCS11 key store. See also -pkcs11lib.
-authpin <pin>
Replace <pin> with the pin to use for accessing the key associated with the certificate.
-certstore <trust-store>
Replace <trust-store> with the name of a file containing root CAs and subordinate CAs.
-signcert <certificate>
The certificate to use for signing the OCSP request. Replace <certificate> with either the filename of PKCS12 encoded token or unique part of subject DN of certificates in PKCS11 key store. See also -pkcs11lib.
-signpin <pin>
Replace <pin> with the pin to use for accessing the key associated with the certificate.
-chain
Use this option to add a certificate chain to the signed OCSP request. Only the signature certificate will be used in the signed OCSP request by default.
-nochain
Use this option to not add the signature certificate or chain to the signed OCSP request.
-nonce
Use this option to add a random nonce to the request.
-pkcs11lib <lib>
Replace <lib> with the name of a PKCS11 library. Must be specified to use authentication or signature certificate in a PKCS11 key store.
-provider <provider>
Replace <provider> with the provider name or class name of a JCE provider to perform the signature.
-servicelocator <url>
Replace <url> with the location of an alternate OCSP responder that the responder we query can redirect the request to.
-signalg <algorithm>
Replace <algorithm> with the name of the signature algorithm to use.
-url <url>
Replace <url> with the location of the OCSP responder to send a request to.
-verbose
Use this option to print out debug data and more information about the response.
<serial-nr>
Either a file containing the certificate one wants to query the status of or a certificate serial number and issuer name specified as: <number>:<issuer DN or part of>. The number can be specified either as decimal or as hexadecimal, prefixed with 0x.
