OpenSSL::Timestamp::Request

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:

version is set to 1
cert_requested is set to true
algorithm, message_imprint, policy_id, and nonce are set to false

Public Class Methods

OpenSSL::Timestamp::Request.new(file) → request click to toggle source

OpenSSL::Timestamp::Request.new(string) → request

OpenSSL::Timestamp::Request.new → empty request

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

algorithm → string click to toggle source

Returns the 'short name' of the object identifier that represents the algorithm that was used to create the message imprint digest.

 
               static VALUE
ossl_ts_req_get_algorithm(VALUE self)
{
    TS_REQ *req;
    TS_MSG_IMPRINT *mi;

    return get_asn1obj(algor->algorithm);
}

algorithm = "string" → string click to toggle source

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

Example:¶ ↑

    GetTSRequest(self, req);
    obj = obj_to_asn1obj(algo);
    mi = TS_REQ_get_msg_imprint(req);
    algor = TS_MSG_IMPRINT_get_algo(mi);
    if (!X509_ALGOR_set0(algor, obj, V_ASN1_NULL, NULL)) {
        ASN1_OBJECT_free(obj);
        ossl_raise(eTimestampError, "X509_ALGOR_set0");
    }

    return algo;
}

cert_requested = boolean → true or false click to toggle source

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

ossl_ts_req_set_cert_requested(VALUE self, VALUE requested)
{
    TS_REQ *req;

    GetTSRequest(self, req);
    TS_REQ_set_cert_req(req, RTEST(requested));

    return requested;
}

Indicates whether the response shall contain the timestamp authority's certificate or not.

 
               static VALUE

{
    TS_REQ *req;

    GetTSRequest(self, req);
    return TS_REQ_get_cert_req(req) ? Qtrue: Qfalse;
}

message_imprint → string or nil click to toggle source

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

 
               static VALUE
ossl_ts_req_get_msg_imprint(VALUE self)
{
    TS_REQ *req;
    TS_MSG_IMPRINT *mi;
    ASN1_OCTET_STRING *hashed_msg;
    VALUE ret;

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

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

    return ret;
}

message_imprint = "string" → string click to toggle source

Set the message imprint digest.

 
               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;
}

nonce → BN or nil click to toggle source

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

 
               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);
}

nonce = number → BN click to toggle source

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.

 
               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;
}

policy_id → string or nil click to toggle source

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

 
               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));
}

policy_id = "string" → string click to toggle source

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"

 
               static VALUE
ossl_ts_req_set_policy_id(VALUE self, VALUE oid)
{
    TS_REQ *req;
    ASN1_OBJECT *obj;
    int ok;

    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;
}

to_der → DER-encoded string click to toggle source

DER-encodes this Request.

 
               static VALUE

    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);
}

version → Integer click to toggle source

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

 
               static VALUE
ossl_ts_req_get_version(VALUE self)
{
    TS_REQ *req;

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

version = number → Integer click to toggle source

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

 
               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;
}
