I worked on elliptic curve cryptography by using java program with NetBeans I try make code for encrypt and decrypt text file by elgamal elliptic curve method my code work fine but I have problem.
I like convert each character in text file to EcPoint for encrypt and vice versa when Decrypt but I can't do that.
