class OpenSSL::OCSP::Request

An OpenSSL::OCSP::Request contains the certificate information for determining if a certificate has been revoked or not. A Request can be created for a certificate or from a DER-encoded request created elsewhere.

Public Class Methods

OpenSSL::OCSP::Request.new → request

OpenSSL::OCSP::Request.new(request_der) → request

Creates a new OpenSSL::OCSP::Request. The request may be created empty or from a request_der string.

static VALUE
ossl_ocspreq_initialize(int argc, VALUE *argv, VALUE self)
{
    VALUE arg;
    OCSP_REQUEST *req, *req_new;
    const unsigned char *p;

        StringValue(arg);
        p = (unsigned char *)RSTRING_PTR(arg);
        req_new = d2i_OCSP_REQUEST(NULL, &p, RSTRING_LEN(arg));
        if (!req_new)
            ossl_raise(eOCSPError, "d2i_OCSP_REQUEST");
        SetOCSPReq(self, req_new);

Public Instance Methods

add_certid(certificate_id) → request

Adds certificate_id to the request.

static VALUE
ossl_ocspreq_add_certid(VALUE self, VALUE certid)
{
    OCSP_REQUEST *req;
    OCSP_CERTID *id, *id_new;

    GetOCSPReq(self, req);
    GetOCSPCertId(certid, id);

    if (!(id_new = OCSP_CERTID_dup(id)))
        ossl_raise(eOCSPError, "OCSP_CERTID_dup");
    if (!OCSP_request_add0_id(req, id_new)) {
        OCSP_CERTID_free(id_new);
        ossl_raise(eOCSPError, "OCSP_request_add0_id");
    }

    return self;
}

add_nonce(nonce = nil) → request

Adds a nonce to the OCSP request. If no nonce is given a random one will be generated.

The nonce is used to prevent replay attacks but some servers do not support it.

static VALUE
ossl_ocspreq_add_nonce(int argc, VALUE *argv, VALUE self)
{
    OCSP_REQUEST *req;
    VALUE val;
    int ret;

    rb_scan_args(argc, argv, "01", &val);
    if(NIL_P(val)) {
        GetOCSPReq(self, req);
        ret = OCSP_request_add1_nonce(req, NULL, -1);
    }
    else{
        StringValue(val);
        GetOCSPReq(self, req);
        ret = OCSP_request_add1_nonce(req, (unsigned char *)RSTRING_PTR(val), RSTRING_LENINT(val));
    }
    if(!ret) ossl_raise(eOCSPError, NULL);

    return self;
}

certid → [certificate_id, ...]

Returns all certificate IDs in this request.

static VALUE
ossl_ocspreq_get_certid(VALUE self)
{
    OCSP_REQUEST *req;
    OCSP_ONEREQ *one;
    OCSP_CERTID *id;
    VALUE ary, tmp;
    int i, count;

    GetOCSPReq(self, req);
    count = OCSP_request_onereq_count(req);
    ary = (count > 0) ? rb_ary_new() : Qnil;
    for(i = 0; i < count; i++){
        one = OCSP_request_onereq_get0(req, i);
        tmp = NewOCSPCertId(cOCSPCertId);
        if(!(id = OCSP_CERTID_dup(OCSP_onereq_get0_id(one))))
            ossl_raise(eOCSPError, NULL);
        SetOCSPCertId(tmp, id);
        rb_ary_push(ary, tmp);
    }

    return ary;
}

check_nonce(response) → result

Checks the nonce validity for this request and response.

The return value is one of the following:

-1: nonce in request only.
0: nonces both present and not equal.
1: nonces present and equal.
2: nonces both absent.
3: nonce present in response only.

For most responses, clients can check result > 0. If a responder doesn’t handle nonces result.nonzero? may be necessary. A result of 0 is always an error.

static VALUE
ossl_ocspreq_check_nonce(VALUE self, VALUE basic_resp)
{
    OCSP_REQUEST *req;
    OCSP_BASICRESP *bs;
    int res;

    GetOCSPReq(self, req);
    GetOCSPBasicRes(basic_resp, bs);
    res = OCSP_check_nonce(req, bs);

    return INT2NUM(res);
}

initialize_copy (p1)

static VALUE
ossl_ocspreq_initialize_copy(VALUE self, VALUE other)
{
    OCSP_REQUEST *req, *req_old, *req_new;

    rb_check_frozen(self);
    GetOCSPReq(self, req_old);
    GetOCSPReq(other, req);

    req_new = ASN1_item_dup(ASN1_ITEM_rptr(OCSP_REQUEST), req);
    if (!req_new)
        ossl_raise(eOCSPError, "ASN1_item_dup");

    SetOCSPReq(self, req_new);
    OCSP_REQUEST_free(req_old);

    return self;
}

sign(cert, key, certs = nil, flags = 0, digest = nil) → self

Signs this OCSP request using cert, key and optional digest. If digest is not specified, SHA-1 is used. certs is an optional Array of additional certificates which are included in the request in addition to the signer certificate. Note that if certs is nil or not given, flag OpenSSL::OCSP::NOCERTS is enabled. Pass an empty array to include only the signer certificate.

flags is a bitwise OR of the following constants:

OpenSSL::OCSP::NOCERTS: Don’t include any certificates in the request. certs will be ignored.

static VALUE
ossl_ocspreq_sign(int argc, VALUE *argv, VALUE self)
{
    VALUE signer_cert, signer_key, certs, flags, digest;
    OCSP_REQUEST *req;
    X509 *signer;
    EVP_PKEY *key;
    STACK_OF(X509) *x509s = NULL;
    unsigned long flg = 0;
    const EVP_MD *md;
    int ret;

    rb_scan_args(argc, argv, "23", &signer_cert, &signer_key, &certs, &flags, &digest);
    GetOCSPReq(self, req);
    signer = GetX509CertPtr(signer_cert);
    key = GetPrivPKeyPtr(signer_key);
    if (!NIL_P(flags))
        flg = NUM2INT(flags);
    if (NIL_P(digest))
        md = NULL;
    else
        md = ossl_evp_get_digestbyname(digest);
    if (NIL_P(certs))
        flg |= OCSP_NOCERTS;
    else
        x509s = ossl_x509_ary2sk(certs);

    ret = OCSP_request_sign(req, signer, key, md, x509s, flg);
    sk_X509_pop_free(x509s, X509_free);
    if (!ret) ossl_raise(eOCSPError, NULL);

    return self;
}

signed? → true or false

Returns true if the request is signed, false otherwise. Note that the validity of the signature is not checked. Use verify to verify that.

static VALUE
ossl_ocspreq_signed_p(VALUE self)
{
    OCSP_REQUEST *req;

    GetOCSPReq(self, req);
    return OCSP_request_is_signed(req) ? Qtrue : Qfalse;
}

to_der ()

Returns this request as a DER-encoded string

static VALUE
ossl_ocspreq_to_der(VALUE self)
{
    OCSP_REQUEST *req;
    VALUE str;
    unsigned char *p;
    long len;

    GetOCSPReq(self, req);
    if((len = i2d_OCSP_REQUEST(req, NULL)) <= 0)
        ossl_raise(eOCSPError, NULL);
    str = rb_str_new(0, len);
    p = (unsigned char *)RSTRING_PTR(str);
    if(i2d_OCSP_REQUEST(req, &p) <= 0)
        ossl_raise(eOCSPError, NULL);
    ossl_str_adjust(str, p);

    return str;
}

verify(certificates, store, flags = 0) → true or false

Verifies this request using the given certificates and store. certificates is an array of OpenSSL::X509::Certificate, store is an OpenSSL::X509::Store.

Note that false is returned if the request does not have a signature. Use signed? to check whether the request is signed or not.

static VALUE
ossl_ocspreq_verify(int argc, VALUE *argv, VALUE self)
{
    VALUE certs, store, flags;
    OCSP_REQUEST *req;
    STACK_OF(X509) *x509s;
    X509_STORE *x509st;
    int flg, result;

    rb_scan_args(argc, argv, "21", &certs, &store, &flags);
    GetOCSPReq(self, req);
    x509st = GetX509StorePtr(store);
    flg = NIL_P(flags) ? 0 : NUM2INT(flags);
    x509s = ossl_x509_ary2sk(certs);
    result = OCSP_request_verify(req, x509s, x509st, flg);
    sk_X509_pop_free(x509s, X509_free);
    if (result <= 0)
        ossl_clear_error();

    return result > 0 ? Qtrue : Qfalse;
}
