For part A)

"The class(es) should be able to generate public and private key pairs of arbitrary size and should be able to cipher and decipher short messages. "

java -Dprime_size=500 security.RSA -gen "hello world"

We think yellow matches with yellow, and green matches with green, but are not sure why they used "-Dprime_size". Also not sure why they used "-gen".

Can someone explain why they used -Drime and -gen, and also Professor Guo, is it ok if we just pass the size and message as follows:

---> java RSA 500 helloworld

Thanks
