// Current implementation has the following limitation:
// - Only version 11.3.0 signatures are supported.
// - Only "framework" and "app" bundle types are supported.
// - Page hash array scattering is not supported.
// - Reading and writing binary property lists i snot supported (third-party frameworks with binary Info.plist will not work unless .plist is converted to text format).
// - Requirements code generator is not implemented (only hard-coded requirements for the ad-hoc signing is supported).
// - RFC5652/CMS blob generation is not implemented, supports ad-hoc signing only.
