AES解密及加密任意长度字符串或文件. 经过两个星期的奋战，终于在前人能解密16字节字符串的基础上解密任意长度字符串，并将其封装为类，以后的调用直接引用该类即可，在封装的过程中可真是磕磕碰碰出现诸多问题，不算大，但却真的不容易找到其中的解决的方法。该方法是自己在前人的基础上辛辛苦苦弄出来的，共享出来，对某些人来说可能是垃圾，但对某些人可能还是有一些帮助吧-AES decryption and encryption of arbitrary length strings or files. After two weeks of fighting, and finally be able to decrypt the predecessors on the basis of 16-byte string to decrypt an arbitrary length string, and encapsulate it for the class, call the direct reference to the future This class can, in the process of encapsulation is really bumps arise many problems, not big, but it really is not easy to find one solution. The method is based on their predecessors hard to get out, shared out, for some people might be junk, but some people may still have some help now
