RSA alogo used encryption decryption problem

Question

You have to implement the RSA algorithm from scratch.
•Your implementation should also include Euclid and extended Euclid for finding the inverse. 
•Coding/Encoding of characters for encryption and decryption. 
•The user should be able to configure your algorithm if she/he wants to use some particular n,p,e or d.
•There should also be a default setting so that it can run without any configuration inputs from the user
•It should also have an option to show the entire process set by step or graphically

Answer 1

Is it a challenge or something you need ? If it is a challenge, you should properly flag it as such, if not, what did you try to do to have this result and where are you stuck ?
