Coding a Cracker

[BlueCow]

Hello everyone, I want to code an account cracker for netflix or spotify or whatever for educational purposes ( I know sentry mba exist that's why it's educational) to understand how it's done and what libs and functions to use. I know the basic syntax and have some knowledge of python 3, javascript, C# and C++. I have looked around on the internet for some info, but since cracking accounts isn't actually very legal I didn't find much about which language is best to do such a thing and besides there are tools coded in C#, C++ and python so I don't know which to use. It's probably partly preference but what is the best language to code an account cracker in ? and what are the libs/functions I need to use. btw I am using a mac so windows.h and that kinda stuff in c++ doesn't work. Also, is perl worth learning for cracking ?

Thank you for reading and helping me out <3
