visualc++实现的sha512算法，可用于计算哈希值-sha512 algorithm visualc++ implemented, it can be used to compute the hash value

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
