Parameter 'secret_ptr' can be declared as pointer to const. However it seems that 'converse' is a callback function, if 'secret_ptr' is declared with const you might also need to cast function pointer(s).

C-style pointer casting detected. C++ offers four different kinds of casts as replacements: static_cast, const_cast, dynamic_cast and reinterpret_cast. A C-style cast could evaluate to any of those automatically, thus it is considered safer if the programmer explicitly states which kind of cast is expected.

Class 'PamPrivate' has a constructor with 1 argument that is not explicit. Such, so called "Converting constructors", should in general be explicit for type safety reasons as that prevents unintended implicit conversions.
