An OpenSSL::OCSP::Request contains the certificate information for determining if a certificate has been revoked or not. A Request can be created for a certificate or from a DER-encoded request created elsewhere.
static VALUE

{
VALUE arg;
const unsigned char *p;

if(!x){
ossl_raise(eOCSPError, "cannot load DER encoded request");
}
}
return self;
}
Creates a new OpenSSL::OCSP::Request. The request may be created empty or from a request_der string.
static VALUE

{
OCSP_REQUEST *req;

ossl_raise(eOCSPError, "OCSP_request_add0_id");
}

}
Adds certificate_id to the request.

}
if(!ret) ossl_raise(eOCSPError, NULL);
return self;
}
Adds a nonce to the OCSP request. If no nonce is given a random one will be generated.
The nonce is used to prevent replay attacks but some servers do not support it.
static VALUE
ossl_ocspreq_get_certid(VALUE self)

SetOCSPCertId(tmp, id);
rb_ary_push(ary, tmp);
}
return ary;
}
Returns all certificate IDs in this request.
static VALUE

return INT2NUM(res);
}
Checks the nonce validity for this request and response.
The return value is one of the following:
- -1
-
nonce in request only.
- 0
-
nonces both present and not equal.
- 1
-
nonces present and equal.
- 2
-
nonces both absent.
- 3
-
nonce present in response only.
For most responses, clients can check result > 0. If a responder doesn’t handle nonces result.nonzero? may be necessary. A result of 0 is always an error.

Signs this OCSP request using signer_cert and signer_key. certificates is an optional Array of certificates that may be included in the request.

Verifies this request using the given certificates and X509 store.
