OpenSSL::OCSP::BasicResponse
家长：对象 （Parent:Object）
OpenSSL :: OCSP :: BasicResponse 包含从 OpenSSL :: OCSP :: Request 创建的证书检查的状态。BasicResponse 比 Response 更详细。
公共类方法
OpenSSL :: OCSP :: BasicResponse.new（der_string = nil）→basic_response 显示源文件
创建一个新的 BasicResponse。如果der_string给出，则解码der_string为 DER。
static VALUE

OCSP_BASICRESP *res, *res_new;

}公共实例方法
add_nonce（nonce = nil）显示源文件
添加nonce到此响应。如果不提供随机数，则会添加随机数。
static VALUE
ossl_ocspbres_add_nonce(int argc, VALUE *argv, VALUE self)
{
OCSP_BASICRESP *bs;
VALUE val;
int ret;
rb_scan_args(argc, argv, "01", &val);

}
if(!ret) ossl_raise(eOCSPError, NULL);
return self;
}add_status（certificate_id，status，reason，revocation_time，this_update，next_update，扩展）→basic_response显示源代码
添加证书状态certificate_id。status是地位，必须是其中的一个：
- OpenSSL::OCSP::V_CERTSTATUS_GOOD
- OpenSSL::OCSP::V_CERTSTATUS_REVOKED
- OpenSSL::OCSP::V_CERTSTATUS_UNKNOWN
reason和revocation_time只有在statusOpenSSL :: OCSP :: V_CERTSTATUS_REVOKED 时才能给出。reason描述了撤销的原因，并且必须是OpenSSL :: OCSP :: REVOKED_STATUS_ *常量之一。revocation_time是证书被撤销的时间。
this_update和next_update指出该状态经过验证的时间是正确的，以及分别提供更新信息的时间。next_update是可选的。
extensions是一个包含在 SingleResponse 中的 OpenSSL :: X509 :: Extension 数组。这也是可选的。
需要注意的是时间，revocation_time，this_update和next_update可以在整数或Time对象的规定。如果它们是整型，则将其视为当前时间的相对秒数。

}sign(cert, key, certs = nil, flags = 0, digest = nil) → self 显示源
标志使用此 OCSP 响应cert，key以及可选的digest。它的行为与 OpenSSL :: OCSP :: Request＃标记类似。
flags 可以包括：
OpenSSL::OCSP::NOCERTS
不包括证书
OpenSSL::OCSP::NOTIME
不要设置生产
OpenSSL::OCSP::RESPID_KEY
使用签名者的公钥哈希作为 responderID

}状态 status → statuses显示来源
返回此响应的状态数组。每个状态都包含 CertificateId，状态（0表示正确，1表示撤销，2表示未知），状态原因，撤销时间，此更新时间，下次更新时间以及OpenSSL列表： ：X509 ::扩展。

#if (OPENSSL_VERSION_NUMBER < 0x1000202fL) || defined(LIBRESSL_VERSION_NUMBER)
/*
* OpenSSL had a bug that it doesn't use the certificates in x509s for
* verifying the chain. This can be a problem when the response is signed by
* a certificate issued by an intermediate CA.
*
* root_ca
* |
* intermediate_ca
* |-------------|
* end_entity ocsp_signer
*
* When the certificate hierarchy is like this, and the response contains
* only ocsp_signer certificate, the following code wrongly fails.
*
* store = OpenSSL::X509::Store.new; store.add_cert(root_ca)
* basic_response.verify([intermediate_ca], store)
*
* So add the certificates in x509s to the embedded certificates list first.
*
* This is fixed in OpenSSL 0.9.8zg, 1.0.0s, 1.0.1n, 1.0.2b. But it still
* exists in LibreSSL 2.1.10, 2.2.9, 2.3.6, 2.4.1.
