# 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`.

### Public Class Methods

OpenSSL::OCSP::BasicResponse.new(der_string = nil) → basic_response click to toggle source

Creates a new `BasicResponse`. If der_string is given, decodes der_string as DER.

                   static VALUE
    ossl_ocspbres_initialize(int argc, VALUE *argv, VALUE self)
    {
        VALUE arg;
        OCSP_BASICRESP *res, *res_new;
        const unsigned char *p;

        rb_scan_args(argc, argv, "01", &arg);
        if (!NIL_P(arg)) {
            GetOCSPBasicRes(self, res);
            arg = ossl_to_der_if_possible(arg);
            StringValue(arg);
            p = (unsigned char *)RSTRING_PTR(arg);
            res_new = d2i_OCSP_BASICRESP(NULL, &p, RSTRING_LEN(arg));
            if (!res_new)
                ossl_raise(eOCSPError, "d2i_OCSP_BASICRESP");
            SetOCSPBasicRes(self, res_new);
            OCSP_BASICRESP_free(res);
        }

        return self;
    }

### Public Instance Methods

add_nonce(nonce = nil) click to toggle source

Adds nonce to this response. If no nonce was provided a random nonce will be added.

                   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(NIL_P(val)) {
            GetOCSPBasicRes(self, bs);
            ret = OCSP_basic_add1_nonce(bs, NULL, -1);
        }
        else{
            StringValue(val);
            GetOCSPBasicRes(self, bs);
            ret = OCSP_basic_add1_nonce(bs, (unsigned char *)RSTRING_PTR(val), RSTRING_LENINT(val));
        }
        if(!ret) ossl_raise(eOCSPError, NULL);

        return self;
    }

add_status(certificate_id, status, reason, revocation_time, this_update, next_update, extensions) → basic_response click to toggle source

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 ths 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.

            rsn = NUM2INT(reason);
            tmp = rb_protect(add_status_convert_time, revtime, &rstatus);
            if (rstatus) goto err;

        if(rstatus) rb_jump_tag(rstatus);

        return self;
    }

copy_nonce(request) → Integer click to toggle source

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

                   static VALUE
    ossl_ocspbres_copy_nonce(VALUE self, VALUE request)
    {
        OCSP_BASICRESP *bs;

        int ret;

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

        return INT2NUM(ret);
    }

find_response(certificate_id) → SingleResponse | nil click to toggle source

Returns a `SingleResponse` whose CertId matches with certificate_id, or `nil` if this `BasicResponse` does not contain it.

                   static VALUE

        if ((n = OCSP_resp_find(bs, id, -1)) == -1)
            return Qnil;

        sres = OCSP_resp_get0(bs, n);
        sres_new = ASN1_item_dup(ASN1_ITEM_rptr(OCSP_SINGLERESP), sres);
        if (!sres_new)
            ossl_raise(eOCSPError, "ASN1_item_dup");

        return self;

sign(cert, key, certs = nil, flags = 0, digest = nil) → self click to toggle source

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

        if (!ret) ossl_raise(eOCSPError, NULL);

        return self;

status → statuses click to toggle source

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`.

to_der → String click to toggle source

Encodes this basic response into a DER-encoded string.

        return str;

verify(certificates, store, flags = 0) → true or false click to toggle source

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