Encryption/decryption with using cryptography algorithms

Already was realized ElGamal. Elgamal encryption system is an asymmetric key encryption algorithm for public-key cryptography which is based on the Diffie–Hellman key exchange.

Elgamal encryption consists of three components:

1. the keys generator (public and private keys);
2. the encryption algorithm;
3. the decryption algorithm.

RSA:

1. the keys generator (public and private keys);
