Description: 3DES（即Triple DES）是DES向AES过渡的加密算法（1999年，NIST将3-DES指定为过渡的加密标准），是DES的一个更安全的变形。它以DES为基本模块，通过组合分组方法设计出分组加密算法，其具体实现如下：设Ek()和Dk()代表DES算法的加密和解密过程，K代表DES算法使用的密钥，P代表明文，C代表密表，这样，
3DES加密过程为：C=Ek3(Dk2(Ek1(P)))
3DES解密过程为：P=Dk1((EK2(Dk3(C)))

Description: **函数: DesDecString
**目的: 解密给定长度的串
**参数: sKey 密钥串. 一般为8个字节长(实际解密时只用其前8个字节)
** nKeyLen 密钥长度. 如果密钥为字符串(以 \0 结尾)，值可为0
** 如果密钥不足8个字节, 密钥串后面不足的字节以 \0 填充
** sSrc 解密前的串. 为8个倍数字节长
** nSrcLen 解密前的串长度. 该串长度必须为8的倍数个字节
** sDest 存放解密后的串. 为nSrcLen字节长, 如果是字符串, 调用者自己负责在尾部加 \0
** nDestLen 存放解密后的串的缓冲长度值. 如果该长度为0, 表示缓冲区足够大(至少nSrclen)
**返回值: 0 成功
** -1 密钥长度或解密前的串长度或解密后的串长度小于0
** -2 存放解密后的串的缓冲不够大
** -3 密钥为空或串指针为空,或者加密前的串为空或串指针为空,或者加密后的串指针为空
** -4 加密前的串长度为0或不是8的倍数-*

Description: 3DES又称Triple DES，是DES加密算法的一种模式，它使用3条56位的密钥对数据进行三次加密。数据加密标准（DES）是美国的一种由来已久的加密标准，它使用对称密钥加密法，并于1981年被ANSI组织规范为ANSI X.3.92。DES使用56位密钥和密码块的方法，而在密码块的方法中，文本被分成64位大小的文本块然后再进行加密。比起最初的DES，3DES更为安全。-3DES, also known as Triple DES, DES encryption algorithm is a model that uses three 56-bit key three times the data encryption. Data Encryption Standard (DES) is a long-standing United States encryption standard that uses symmetric key encryption method, and in 1981 organized by ANSI standard is ANSI X.3.92. 56-bit DES key and password using the block method, the method in the code block, the text is divided into 64-bit size of the text block and then encrypted. Than the original DES, 3DES is more secure.
