I'm trying to encrypt a message with RSA. I'd like to do this as part of a game/scavenger hunt I'm organizing for the holidays. I understand how RSA encryption works but I'm having trouble finding a way to encrypt and decrypt the message.
I found this site to help with encryption/decryption:
but I can't seem to come up with any keys that make it easy to go back and forth for encryption/decryption of this message:
11-14-23-6 1-11 19 5-7-7-11-23
How can I come up with relatively simply keys to use? I know the purpose of RSA is to be difficult to crack but in this case it doesn't matter, I just don't want super long keys.
