class OpenSSL::Timestamp::Request

Parent:
Object

Allows to create timestamp requests or parse existing ones. A Request is also needed for creating timestamps from scratch with Factory. When created from scratch, some default values are set:

Public Class Methods

OpenSSL::Timestamp::Request.new(file) → request Show source
OpenSSL::Timestamp::Request.new(string) → request
OpenSSL::Timestamp::Request.new → empty request 
static VALUE
ossl_ts_req_initialize(int argc, VALUE *argv, VALUE self)
{
    TS_REQ *ts_req = DATA_PTR(self);
    BIO *in;
    VALUE arg;

    if(rb_scan_args(argc, argv, "01", &arg) == 0) {
        return self;
    }

    arg = ossl_to_der_if_possible(arg);
    in = ossl_obj2bio(&arg);
    ts_req = d2i_TS_REQ_bio(in, &ts_req);
    BIO_free(in);
    if (!ts_req)
        ossl_raise(eTimestampError, "Error when decoding the timestamp request");
    DATA_PTR(self) = ts_req;

    return self;
}

When creating a Request with the File or string parameter, the corresponding File or string must be DER-encoded.

        ossl_raise(eTimestampError, "X509_ALGOR_set0");
    }

    return algo;

Allows to set the object identifier or the 'short name' of the algorithm that was used to create the message imprint digest.

Example:

request.algorithm = "SHA1"

    TS_REQ_set_cert_req(req, RTEST(requested));

    return requested;
}

Specify whether the response shall contain the timestamp authority's certificate or not. The default value is true.

cert_requested? → true or false Show source 
static VALUE
ossl_ts_req_get_cert_requested(VALUE self)
{
    TS_REQ *req;

    GetTSRequest(self, req);

    hashed_msg = TS_MSG_IMPRINT_get_msg(mi);

    ret = rb_str_new((const char *)hashed_msg->data, hashed_msg->length);

    return ret;
}

Returns the message imprint (digest) of the data to be timestamped.

message_imprint = "string" → string Show source 
static VALUE
ossl_ts_req_set_msg_imprint(VALUE self, VALUE hash)
{
    TS_REQ *req;
    TS_MSG_IMPRINT *mi;
    StringValue(hash);

    GetTSRequest(self, req);
    mi = TS_REQ_get_msg_imprint(req);
    if (!TS_MSG_IMPRINT_set_msg(mi, (unsigned char *)RSTRING_PTR(hash), RSTRING_LENINT(hash)))
        ossl_raise(eTimestampError, "TS_MSG_IMPRINT_set_msg");

    return hash;
}

Set the message imprint digest.

nonce → BN or nil Show source 
static VALUE
ossl_ts_req_get_nonce(VALUE self)
{
    TS_REQ *req;
    const ASN1_INTEGER * nonce;

    GetTSRequest(self, req);
    if (!(nonce = TS_REQ_get_nonce(req)))
        return Qnil;
    return asn1integer_to_num(nonce);
}

Returns the nonce (number used once) that the server shall include in its response.

nonce = number → BN Show source 
static VALUE
ossl_ts_req_set_nonce(VALUE self, VALUE num)
{
    TS_REQ *req;
    ASN1_INTEGER *nonce;
    int ok;

    GetTSRequest(self, req);
    nonce = num_to_asn1integer(num, NULL);
    ok = TS_REQ_set_nonce(req, nonce);
    ASN1_INTEGER_free(nonce);
    if (!ok)
        ossl_raise(eTimestampError, NULL);
    return num;
}

Sets the nonce (number used once) that the server shall include in its response. If the nonce is set, the server must return the same nonce value in a valid Response.

policy_id → string or nil Show source 
static VALUE
ossl_ts_req_get_policy_id(VALUE self)
{
    TS_REQ *req;

    GetTSRequest(self, req);
    if (!TS_REQ_get_policy_id(req))
        return Qnil;
    return get_asn1obj(TS_REQ_get_policy_id(req));
}

Returns the 'short name' of the object identifier that represents the timestamp policy under which the server shall create the timestamp.

policy_id = "string" → string Show source 
static VALUE
ossl_ts_req_set_policy_id(VALUE self, VALUE oid)
{
    TS_REQ *req;
    ASN1_OBJECT *obj;

    GetTSRequest(self, req);
    obj = obj_to_asn1obj(oid);
    ok = TS_REQ_set_policy_id(req, obj);
    ASN1_OBJECT_free(obj);
    if (!ok)
        ossl_raise(eTimestampError, "TS_REQ_set_policy_id");

    return oid;
}

Allows to set the object identifier that represents the timestamp policy under which the server shall create the timestamp. This may be left nil, implying that the timestamp server will issue the timestamp using some default policy.

Example:

request.policy_id = "1.2.3.4.5"
to_der → DER-encoded string Show source 
static VALUE
ossl_ts_req_to_der(VALUE self)
{
    TS_REQ *req;
    TS_MSG_IMPRINT *mi;
    X509_ALGOR *algo;
    ASN1_OCTET_STRING *hashed_msg;

    GetTSRequest(self, req);
    mi = TS_REQ_get_msg_imprint(req);

    algo = TS_MSG_IMPRINT_get_algo(mi);
    if (OBJ_obj2nid(algo->algorithm) == NID_undef)
        ossl_raise(eTimestampError, "Message imprint missing algorithm");

    hashed_msg = TS_MSG_IMPRINT_get_msg(mi);
    if (!hashed_msg->length)
        ossl_raise(eTimestampError, "Message imprint missing hashed message");

    return asn1_to_der((void *)req, (int (*)(void *, unsigned char **))i2d_TS_REQ);
}

DER-encodes this Request.

version → Integer Show source 
static VALUE
ossl_ts_req_get_version(VALUE self)
{
    TS_REQ *req;

    GetTSRequest(self, req);
    return LONG2NUM(TS_REQ_get_version(req));
}

Returns the version of this request. 1 is the default value.

version = number → Integer Show source 
static VALUE
ossl_ts_req_set_version(VALUE self, VALUE version)
{
    TS_REQ *req;
    long ver;

    if ((ver = NUM2LONG(version)) < 0)
        ossl_raise(eTimestampError, "version must be >= 0!");
    GetTSRequest(self, req);
    if (!TS_REQ_set_version(req, ver))
        ossl_raise(eTimestampError, "TS_REQ_set_version");

    return version;
}

Sets the version number for this Request. This should be 1 for compliant servers.
