class 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

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

    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

Source

static VALUE

    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

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;

        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.
