# RSA implementation using GMP

Simple RSA key generation, text encryption and ciphertext decryption.

## usage



  
key generation:

  
input: ./rsa -g B
output: P Q N E D



  
text encryption:

  
input: ./rsa -e E N M
output: C



  
ciphertext decryption:

  
input: ./rsa -d D N C
output: M


B ... size of public modulus in bits


P ... randomly generated prime number


Q ... randomly generated prime number


N ... public modulus


E ... public exponent


D ... private exponent


M ... plaintext message (number, not text)


C ... ciphertext message (number, not text)
