Coding Challenge for Pro Core
This app is a game where users can encrypt their messages using RSA Encryption. More information about RSA Encrypion can be found here: https://en.wikipedia.org/wiki/RSA_(cryptosystem)#Operation
The user can plug in a message that will be encrypted into a string of numbers. The user can also plug in an encoded message, along with the necessary keys, to decode the message.
In the future, I hope to implement networking so that users can share their encrypted messages across different devices.
Notes: I used JKBigInteger to handle some of the operations of RSA Encryption, where certain numbers exceeded the size of unsigned long long. I generated the prime numbers with the Sieve of Eratosthenes. Users can choose to change the range of the prime numbers through the initializer in AppDelegate.m.
