Wojciech Trocki If we move to crypto API then we don't need any third-party packages, which is good. If web browser is the only environment we support, then we can include it in the SDK as there is no risk there. However, I don't think it supports environment like react-native, and it will cause us problem later on when we need to add support for it. So my thinking is still to leave it as a separate optional module.
