内核加解密算法 加解密函数库及其使用说明，详见附件。 find_cipher_by_name中参数ciphername可取的值为下面的组合，对应不同的模式: (des,des_ede3,aes,blowfish,cast5,dfc,idea,mars,rc5,rc6,serpent,twofish)-ecb (des,des_ede3,aes,blowfish,cast5,dfc,idea,mars,rc5,rc6,serpent,twofish)-cbc (des,des_ede3,aes,b

通过实现DES算法，同时学习组合密码常用的代换、移位等运算的实现。-DES algorithm by implementing the same time, the password used in the substitution learning portfolio, shift and other operations to achieve.
