-The purpose of this post is to demonstrate how emulation can be used to find solutions to a few keygenme-style crackme programs. 
-It is not always necessary or efficient to rely on just a disassembler or debugger when emulation can be used to assist with the analysis.
-In fact, by using tools like angr and Cutter one can save a significant amount of time when solving challenges like these.
-Rather than post each write-up seperately, the solutions to 5 challenges are posted together here. 
-They are of rather low difficulty, so they should be accessible to beginners.
