c++的基于openssl实现的简单aes文件加密类 -c++ realize openssl based on a simple type of file encryption aes

该程序实现单层的DES加密算法，其中CDes.cpp为源程序，其中调用的文件功能如下：dataofText.txt文件是输入的明文，以换行分割各个数据；dataofKey.txt文件时输入的密钥，以换行分割；dataofDES.txt文件是输出的加密数据，其中包括各轮子密钥以及各轮加密输出，以及最后得到的密文，在文件中都有说明。-the realization of the single DES encryption algorithm, which CDes.cpp to source files, Calling the document which functions as follows : dataofText.txt document is imported specifically, in exchange for various bits of data; dataofKey.txt paper input key to change bits; dataofDES.txt document is the output data encryption, including the wheels round and the key encryption exports, and finally the secret text in the document have been described.

对文件加密的试验程序。-document encryption testing procedures.

写专属或加密程序。 程序应该采取作为输入由程序然后加密的文件名。 程序应该要求用户输入密钥，应该用于加密文件。 程序的输出应该进入一个文件以同一个文件名，但.ENC引伸。-Write an exclusive-OR encryption program. The program should take as input a filename that is then encrypted by the program. The program should ask the user to input an encryption key, which should be used to encrypt the file. The output of the program should go into a file with the same filename but a .ENC extension.
