SHA1加密 全称:安全哈希算法(Secure Hash Algorithm)主要适用于数字签名标准(Digital Signature StandardDSS)里面定义的数字签名算法(Digital Signature Algorithm DSA),SHA1比MD5的安全性更强。对于长度小于2^64位的消息,SHA1会产生一个160位的消息摘要。Python代码: importhashlib sha1 =hashlib.sha1() data =...

全称:MD5消息摘要算法(英语:MD5 Message-Digest Algorithm),一种被广泛使用的密码散列函数,可以产生出一个128位(16字节)的散列值(hash value),用于确保信息传输完整一致。md5加密算法是不可逆的,所以解密一般都是通过暴力穷举方法,通过网站的接口实现解密。Python代码: ...
