+// 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.
