RSA算法的C语言实现 1.密钥的产生 (1)选两个安全的大素数p和q。 (2)计算n=p×q，φ(n)=(p-1)(q-1)，其中φ(n)是n的欧拉函数值。 (3)选一整数e，满足1<e<φ(n)，且gcd(φ(n),e)=1。 (4)计算d，满足de≡1 modφ(n)，即d是e在模φ(n)下的乘法逆元，因e与φ(n)互素，由模运算可知，它的乘法逆元一定存在。 (5)以{e,n}为公开钥，{d,n}为秘密钥。 2.加密 加密时首先将明文M比特串分组

Solve descrete log problem using meet in the middle attack. More formally, write a program to compute discrete log modulo a prime p. Let g be some element in Z p and suppose you are given h in Z p such that h = gx where 1 ≤ x ≤ 240. Your goal
