RSA algorithm for encryption and decryption.

1-Key Generation

1-Choose tow primes (P , Q) .
2-Compute n = P * Q .
3-Compute Euler ℰ = (P-1)(Q-1).
4-Choose e with this conditions 1 < e < ℰ & must be coprime with ℰ .
Key is (n , e)

2-Message Encryption

C = m^e mod n
C : message after encrypted
m: message before encrypted
n&e is the key

3-Message Decryption

M = c^d mod n
M: message before encrypted
c: message after encrypted
d= e^-1 mod ℰ
n&e is the key ℰ
