RSA加密 设p,q是两个超级大的素数,N=pq,数据通过欧拉函数φ(N)来加密,而欧拉函数φ(N)满足φ(N)= φ(pq)=(p-1)(q-1),如果要算出φ(N),就必须知道p和q。并且这有一点好处,某人可以公开宣布他的密钥e以及N,任何人都可以给他发送密文,但是只有他能看懂。因为想要破解密码,就必须知道那两个超级大素...

MD5算法广泛应用于数字签名、数据完整性校验、密码学等领域。 MD5(Message-Digest Algorithm 5)是一种常用的哈希算法,它将任意长度的消息压缩成一个128位的消息摘要(即哈希值),并且具有不可逆性、唯一性、抗碰撞性等特点。<a name="bEnci"></a> 二、MD5加密解密的原理?
