class OpenSSL::OCSP::BasicResponse

An OpenSSL::OCSP::BasicResponse contains the status of a certificate check which is created from an OpenSSL::OCSP::Request. A BasicResponse is more detailed than a Response.

}

Adds a certificate status for certificate_id. status is the status, and must be one of these:

OpenSSL::OCSP::V_CERTSTATUS_GOOD
OpenSSL::OCSP::V_CERTSTATUS_REVOKED
OpenSSL::OCSP::V_CERTSTATUS_UNKNOWN

reason and revocation_time can be given only when status is OpenSSL::OCSP::V_CERTSTATUS_REVOKED. reason describes the reason for the revocation, and must be one of OpenSSL::OCSP::REVOKED_STATUS_* constants. revocation_time is the time when the certificate is revoked.

this_update and next_update indicate the time at which the status is verified to be correct and the time at or before which newer information will be available, respectively. next_update is optional.

extensions is an Array of OpenSSL::X509::Extension to be included in the SingleResponse. This is also optional.

Note that the times, revocation_time, this_update and next_update can be specified in either of Integer or Time object. If they are Integer, it is treated as the relative seconds from the current time.

copy_nonce(request) → Integer

Source

static VALUE

    GetOCSPReq(request, req);
    ret = OCSP_copy_nonce(bs, req);

    return INT2NUM(ret);
}

Copies the nonce from request into this response. Returns 1 on success and 0 on failure.

    if (!sres_new)
        ossl_raise(eOCSPError, "ASN1_item_dup");

    sk_X509_pop_free(x509s, X509_free);
    if (!ret) ossl_raise(eOCSPError, NULL);

    return self;
}

Signs this OCSP response using the cert, key and optional digest. This behaves in the similar way as OpenSSL::OCSP::Request#sign.

flags can include:

OpenSSL::OCSP::NOCERTS: don’t include certificates
OpenSSL::OCSP::NOTIME: don’t set producedAt
OpenSSL::OCSP::RESPID_KEY: use signer’s public key hash as responderID

        }
        rb_ary_push(ary, ext);
        rb_ary_push(ret, ary);
    }

    return ret;
}

Returns an Array of statuses for this response. Each status contains a CertificateId, the status (0 for good, 1 for revoked, 2 for unknown), the reason for the status, the revocation time, the time of this update, the time for the next update and a list of OpenSSL::X509::Extension.

This should be superseded by BasicResponse#responses and find_response that return SingleResponse.

Verifies the signature of the response using the given certificates and store. This works in the similar way as OpenSSL::OCSP::Request#verify.
