Description: RC5－CTS模式加密解密算法C++程序实现。
解压之后运行main.dsw.在VC++下面打开，执行之后根据显示首先输入密钥（随便输入不超过16字节的字符串），之后提示输入需要加密的plaintext文件,输入plaintext1.txt，这个文件在压缩包里已经存在，(注意一定要写清楚文件类型名，是个文本文件)，然后根据提示输入加密文件名，可随便输入一个文件名，但是别忘记了类型名.txt，如ciphertext1.txt。因为不输入类型名将来无法打开。之后输入解密之后的文件名，可输入decrypted.txt
结束。
之后打开生成的ciphertext1.txt和decrypted.txt，还有原来的明文文件plaintext1.txt,可以看出decrypted.txt和plaintext1.txt内容一致。ciphertext1.txt由plaintext1.txt加密得到，而decrypted.txt由ciphertext1.txt解密得到-RC5 - CTS mode encryption and decryption algorithm C program.

Description: 文件夹加密工具(开源代码)
软件作者：dyforc
发现文件夹加密的软件较少，而且都不大适合我用，所以写了一个。主要是对指定文件夹和其子目录下所有文件加密。
用到的加密算发是RC4。
本程序特色：
1. 可以指定加密长度（即只对文件的一部分进行加密），（对大文件加密很有用）
2. 可以随机生成动态密钥
（即使加密目录下某个文件的加密密钥被破解了，不影响目录下其他加密过的文件，因为每个文件加密密钥不同，都由输入的密钥随机计算产生）
3. 可以随机化文件名，对文件生成MD5，以此来保障解密成功。
4. 加解密过程中程序允许执行指定脚本。-Folder encryption tool (open source code)
Software Author: dyforc
Found the software folder encryption less, but I do not fit, so to write one. Is the designated folder and all its subdirectories file encryption.
Calculation made use of encryption is RC4.
This procedure features:
1. Can specify the encryption length (that is, only part of the document encryption), (large file encryption useful)
2. Can be randomly generated dynamic key
(Even if encrypted a file directory of the encryption key being cracked, the directory does not affect other encrypted files, because a different encryption key for each document, by the calculation of input generate a random key)
3. Of file name can be random, the document to generate MD5, in order to protect the successful decryption.
4. The process of encryption and decryption process to allow the implementation of the specified script. Platform: |

Description: 使用说明
1. 该工具只支持标准版XXTEA算法加解密，参考Cocos2d-x 3.12版本
2. 支持文件目录和单文件的加解密，注意加解密的输入和输出路径
3. 工具会自动判定文件签名是否符合条件，不符合条件的归为加解密失败
4. 若加解密失败可能原因有格式不对和对文件操作失败引起
5. 解密只识别文件头是否符合，若解密后为乱码则非标准算法或密钥引起。
6. 输出路径若存在同名文件则会直接覆盖掉。
7. 请不要强制关闭软件以免引起错误，具体加密完成请查看输出日志。(Instructions
1. This tool only supports standard version XXTEA encryption and decryption, refer to Cocos 2d-x 3.12 version.
2. Support the encryption and decryption of file directory and single file, pay attention to the input and output paths of encryption and decryption.
3. The tool will automatically determine whether the signature of the document meets the requirements, and the failure of encryption and decryption will be attributed to the failure of the qualified signature.
4. If encryption and decryption fails, there may be format errors and file operation failures.
5. Decrypting only identifies whether the header of the file is in conformity with the standard algorithm or key if the decryption is scrambled.
6. If the output path has the same name file, it will be overwritten directly.
7. Please do not force the shutdown of the software to avoid errors. Please check the output log when the encryption is completed.) Platform: |
