@文心快码BaiduComatemd5 function in sql server 文心快码BaiduComate 在SQL Server中,MD5函数用于生成数据的MD5哈希值。MD5是一种广泛使用的哈希算法,可以将任意长度的数据“散列”成一个128位的哈希值(通常以32位十六进制数表示)。尽管MD5在安全性上存在一些已知的弱点,但在某些情况下,它仍然被用于数据完整性验证...
MySQL and PostgreSQL's MD5() functions are nice, simple, ways to hash your data. Unfortunately, SQL Server 2005 and up (sorry, in order to get it working in SQL Server 2000, you'll need to try astored procedure), you can use theHASHBYTES()function. In a recent SQL Server port of ...

因为我们初始的数据有问题,需要批量的导入,我们创建了oracle的MD5算法,对用户名和密码进行了加密;简单的两步操作:1、写函数:createorreplacefunction"MD52"(passwdinvarchar2)returnvarchar2isretvalvarchar2(32);beginretval:=utl_raw.cast_to_raw(dbms_obfu ...
与对称加密算法不同的是,进行加密与解密使用的是不同的秘钥,有一个公钥-私钥对,秘钥正确才可以正常的进行加解密。
