公共类方法

OpenSSL::OCSP::SingleResponse.new(der_string) → SingleResponse

源代码

static VALUE
ossl_ocspsres_initialize(VALUE self, VALUE arg)
{
    OCSP_SINGLERESP *res, *res_new;
    const unsigned char *p;

    arg = ossl_to_der_if_possible(arg);
    StringValue(arg);
    GetOCSPSingleRes(self, res);

    p = (unsigned char*)RSTRING_PTR(arg);
    res_new = d2i_OCSP_SINGLERESP(NULL, &p, RSTRING_LEN(arg));
    if (!res_new)
        ossl_raise(eOCSPError, "d2i_OCSP_SINGLERESP");
    SetOCSPSingleRes(self, res_new);
    OCSP_SINGLERESP_free(res);

    return self;
}

从 der_string 创建一个新的 SingleResponse。

公共实例方法

cert_status → Integer

源代码

static VALUE
ossl_ocspsres_get_cert_status(VALUE self)
{
    OCSP_SINGLERESP *sres;
    int status;

    GetOCSPSingleRes(self, sres);
    status = OCSP_single_get0_status(sres, NULL, NULL, NULL, NULL);
    if (status < 0)
        ossl_raise(eOCSPError, "OCSP_single_get0_status");

    return INT2NUM(status);
}

返回由 certid 标识的证书的状态。返回值可能是以下常量之一

V_CERTSTATUS_GOOD
V_CERTSTATUS_REVOKED
V_CERTSTATUS_UNKNOWN

当状态为 V_CERTSTATUS_REVOKED 时，可以使用 revocation_time 获取证书被吊销的时间。

certid → CertificateId

源代码

static VALUE
ossl_ocspsres_get_certid(VALUE self)
{
    OCSP_SINGLERESP *sres;
    OCSP_CERTID *id;

    GetOCSPSingleRes(self, sres);
    id = OCSP_CERTID_dup((OCSP_CERTID *)OCSP_SINGLERESP_get0_id(sres)); /* FIXME */

    return ossl_ocspcertid_new(id);
}

返回此 SingleResponse 所针对的 CertificateId。

check_validity(nsec = 0, maxsec = -1) → true | false

源代码

static VALUE
ossl_ocspsres_check_validity(int argc, VALUE *argv, VALUE self)
{
    OCSP_SINGLERESP *sres;
    ASN1_GENERALIZEDTIME *this_update, *next_update;
    VALUE nsec_v, maxsec_v;
    int nsec, maxsec, status, ret;

    rb_scan_args(argc, argv, "02", &nsec_v, &maxsec_v);
    nsec = NIL_P(nsec_v) ? 0 : NUM2INT(nsec_v);
    maxsec = NIL_P(maxsec_v) ? -1 : NUM2INT(maxsec_v);

    GetOCSPSingleRes(self, sres);
    status = OCSP_single_get0_status(sres, NULL, NULL, &this_update, &next_update);
    if (status < 0)
        ossl_raise(eOCSPError, "OCSP_single_get0_status");

    ret = OCSP_check_validity(this_update, next_update, nsec, maxsec);

    if (ret)
        return Qtrue;
    else {
        ossl_clear_error();
        return Qfalse;
    }
}

检查此 SingleResponse 的 thisUpdate 和 nextUpdate 字段的有效性。这会检查当前时间是否在 thisUpdate 到 nextUpdate 的范围内。

OCSP 请求可能需要几秒钟，或者时间可能不准确。为了避免拒绝有效的响应，此方法允许时间在当前时间的 nsec 秒内。

某些响应者不会设置 nextUpdate 字段。这可能会导致非常旧的响应被认为是有效的。可以使用 maxsec 参数来限制响应的有效期。

extensions → X509::Extension 的数组

源代码

static VALUE
ossl_ocspsres_get_extensions(VALUE self)
{
    OCSP_SINGLERESP *sres;
    X509_EXTENSION *ext;

    VALUE ary;

    GetOCSPSingleRes(self, sres);

    count = OCSP_SINGLERESP_get_ext_count(sres);
    ary = rb_ary_new2(count);
    for (i = 0; i < count; i++) {
        ext = OCSP_SINGLERESP_get_ext(sres, i);
        rb_ary_push(ary, ossl_x509ext_new(ext)); /* will dup */
    }

    return ary;
}
