C++ (Cpp) toUint8Array Examples

Example #1

File: JSCryptoAlgorithmDictionary.cpp Project: Comcast/WebKitForWayland

static RefPtr<CryptoAlgorithmParameters> createRsaKeyGenParams(ExecState& state, JSValue value)
{
    if (!value.isObject()) {
        throwTypeError(&state);
        return nullptr;
    }

    JSDictionary jsDictionary(&state, value.getObject());
    auto result = adoptRef(*new CryptoAlgorithmRsaKeyGenParams);

    JSValue modulusLengthValue = getProperty(&state, value.getObject(), "modulusLength");
    if (state.hadException())

    // FIXME: Why no EnforceRange? Filed as <https://www.w3.org/Bugs/Public/show_bug.cgi?id=23779>.
    result->modulusLength = convert<uint32_t>(state, modulusLengthValue, NormalConversion);
    if (state.hadException())
        return nullptr;

    JSValue publicExponentValue = getProperty(&state, value.getObject(), "publicExponent");
    if (state.hadException())
        return nullptr;

        return nullptr;
    }
    result->publicExponent.append(publicExponentArray->data(), publicExponentArray->byteLength());

    result->hasHash = getHashAlgorithm(jsDictionary, result->hash, HashRequirement::Optional);

Example #2

File: JSCryptoAlgorithmDictionary.cpp Project: cheekiatng/webkit

{
    if (!value.isObject()) {
        throwTypeError(exec);
        return nullptr;
    }

    auto result = std::make_unique<CryptoAlgorithmRsaKeyGenParams>();

    JSValue modulusLengthValue = getProperty(exec, value.getObject(), "modulusLength");
    if (exec->hadException())
        return nullptr;

    // FIXME: Why no EnforceRange? Filed as <https://www.w3.org/Bugs/Public/show_bug.cgi?id=23779>.
    result->modulusLength = toUInt32(exec, modulusLengthValue, NormalConversion);
    if (exec->hadException())
        return nullptr;

    JSValue publicExponentValue = getProperty(exec, value.getObject(), "publicExponent");
    if (exec->hadException())
        return nullptr;

    RefPtr<Uint8Array> publicExponentArray = toUint8Array(publicExponentValue);
    if (!publicExponentArray) {
        throwTypeError(exec, "Expected a Uint8Array in publicExponent");
        return nullptr;
    }
    result->publicExponent.append(publicExponentArray->data(), publicExponentArray->byteLength());

    return WTF::move(result);
}

Example #3

void JSDictionary::convertValue(JSC::ExecState*, JSC::JSValue value, RefPtr<Uint8Array>& result)
{
    result = toUint8Array(value);
}
