The LENGTH functionsreturn the length of char. LENGTH calculates length usingcharacters as defined by the input character set. --返回以字符为单位的长度. LENGTHB usesbytes instead of characters. --返回以字节为单位的长度.
Length in characters --- 7 The next example assumes a double-byte database character set. SELECT LENGTHB ('CANDIDE') "Length in bytes" FROM DUAL; Length in bytes --- 14

关注上图绿色圈起来的部分,解密之后的最后一个数据块,其结尾应该包含正确的填充序列。如果这点没有满足,那么加/解密程序就会抛出一个填充异常。Padding Oracle Attack的关键就是利用程序是否抛出异常来判断padding是否正确。 (2)攻击者视角 现在让我们来看看在不知道明文的情况下,如何猜解出明文。首先我们将密文分组,...
