How do I use c++ to make my own cypher?

Question

I want to make a cypher to use with my friend but I want to know the best way to go about it because I am new to writing code. Any help would be appreciated and thank you in advance!

Answer 1

@Mia Check out my code (Rail fence cipher) Only encryption part was coded though. If you want to know about rail fence just Google it. :D

Answer 2

@Mia You may look into my codes on String Encryption/Decryption. The algorithm is of the simplest type, so you might want to borrow the idea but create a more complex algorithm.

Answer 3

check this code once,

Answer 4

Actually , the cipher text would be looks like messy :D so that its called cipher text. and BTW yes you can encrypt twice a string but think of the decryption side too. @Mia

Answer 5

Learn about cyphers like Caesar or RSA. Read about bit shifting operators. Once you learn that you can kinda mix your knowledge to create really good cypher ^^

Answer 6

The cipher itself is not dependant on the programming language. Think about what you want to do. make an algorithm about it. Coding that will be simplier.

Answer 7

I have another question about the cypher. I have an idea on how to write it (going with strings) but can I make the code encrypt a message one way and then make it take the encryption and encrypt that one as well without it getting too messy?
