# class OpenSSL::OCSP::SingleResponse

An `OpenSSL::OCSP::SingleResponse` represents an `OCSP` `SingleResponse` structure, which contains the basic information of the status of the certificate.

### Public Class Methods

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

    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;
    }

Creates a new `SingleResponse` from der_string.

### Public Instance Methods

cert_status → Integer
Source

    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);
    }

Returns the status of the certificate identified by the certid. The return value may be one of these constant:

- V_CERTSTATUS_GOOD

- V_CERTSTATUS_REVOKED

- V_CERTSTATUS_UNKNOWN

When the status is V_CERTSTATUS_REVOKED, the time at which the certificate was revoked can be retrieved by `revocation_time`.

certid → CertificateId
Source

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

        GetOCSPSingleRes(self, sres);
        return ossl_ocspcid_new(OCSP_SINGLERESP_get0_id(sres));
    }

Returns the `CertificateId` for which this `SingleResponse` is.

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

    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;
        }
    }

Checks the validity of thisUpdate and nextUpdate fields of this `SingleResponse`. This checks the current time is within the range thisUpdate to nextUpdate.

It is possible that the `OCSP` request takes a few seconds or the time is not accurate. To avoid rejecting a valid response, this method allows the times to be within nsec seconds of the current time.

Some responders don’t set the nextUpdate field. This may cause a very old response to be considered valid. The maxsec parameter can be used to limit the age of responses.
