java - Create a 256 byte RSA encrypted block from a public key -

hello trying write php function/class connect remote (java) server , send message has been encoded 256 byte rsa block using public key.

the github of java server here : https://github.com/vexsoftware/votifier

(search for: protocol documentation).

and every function found on net doesnt need.

b) server responds either default message if send wrong info or (i guessing here) ok message when good.
