Proth.exe is an ancient program that implements Proth's theorem. It is used to test the primality of the following forms:
- kn+1 (Generalized Fermat numbers)
- k•bn±1 (by default b is 2 but it can be changed)
- n•bn±1 (Generalized Cullen/Generalized Woodall numbers)
Due to the age of the program, it is not optimized for use with modern processors and thus should not be used. Instead newer programs such as LLR and PFGW should be used.
