Contemporary RSA-1024 system is used in the current world's computer networks for secure communication and transmission.The RSA -1024 system is absolutely secure from the intruders.However it required huge computational effort during encryption and decryption.This can be solved by the fast exponential method however again required mathematical space and time complexity.Java mathematical tool provides BigInteger APIs are significantly suitable to solve this complexity problem.In this paper RSA public key (e, n) and provate key (d, n) used as 1024 bits long large prime product.The encryption and decryption is accomplished through the methods of BigInteger class.In this paper, pragmatic RSA-2048 cryptosystem is presented for e-mail service.The entire design, implantation and deployment is presented in this paper.
