加密使用64位明文和64位密钥做为输入(均为01字符串)，产生64位的密文做为输出。加解密使用相同的密钥。采用CBC模式对文本加解密.

对话界面:选择加密或解密,输入密钥,在目录中选择明文或密文文件(内容为二进制,.txt文件,),提示加密或解密完成

输出:产生密文文本或明文文本-Encrypted using 64 bit plaintext and a 64 bit key as input (01 string), to generate 64 bit ciphertext as output. Use the same key for encryption and decryption. Using CBC model to text encryption and decryption.

Dialogue interface: the choice of encryption or decryption, the input key, chosen plaintext or ciphertext files in directory (content for the binary,.Txt file, encryption or decryption), suggesting that finish

Output: produce ciphertext or plaintext text
