FileEncrypt

UPXShell--源代码 （ASM版本的，及其高效精妙）-UPXShell- source code (ASM version, and its efficient exquisite) [

说明：  使用维吉尼亚矩阵进行对明文的加密以及解密。(Vigenere matrix is used to encrypt and decrypt plaintext.)

文件加密压缩解压缩系统-file encryption compression decompression system

这是一个在vc环境下编译通过的MD5算法。包含算法源代码和测试主程序。-This is an environment in vc compiled by the MD5 algorithm. Includes algorithm source code and testing main program.

MD5加密算法，实现报文认证！！运算速度快，兼容性好(MD5 encryption algorithm, message authentication realize! ! Computing speed, better compatibility)

实现维吉尼亚密码，用键盘接收明文和密钥，屏幕打印密文和解密后的明文。 可以实现：大小写敏感，明文小写则密文大写，明文大写则密文小写输出，注意输入的健壮性控制，明文字符超出字符集后保留原文(Virginia to achieve the password, use the keyboard to receive the plaintext and the key, the screen printing ciphertext and the decrypted plaintext. Can be achieved: case sensitive, then the ciphertext plaintext lowercase uppercase, lowercase plaintext ciphertext output is capital, pay attention to the robustness of the control input, plaintext characters out retain the original character set)

说明：  利用HASH（采用sha-1算法）算法原理，设计数字签名的水印算法，完成嵌入、（提取）验证，(Use HASH (using sha-1 algorithm) algorithm, design of watermarking algorithms digital signature to complete the embedding, (extract) authentication,)

一个关于串口的简单实现，可以了解基本串口听基本知识-a serial port on the simple realization, we can understand the basic serial listen to the basic knowledge

通过对OpenSSL对称密码算法函数的调用，实现常用的对称加密。这个工具主要的功能已经实现，而且还可以对大文件进行加密，可能效率上还需进一步完善，因为对大文件加密时，太差劲的电脑会感觉有点卡！另外，它还可以对电影加密，不妨一试。-Symmetric cryptographic algorithm through OpenSSL function calls to achieve common symmetric encryption. The main function of this tool has been achieved, but also can encrypt large files, you may need to further improve efficiency, because the large file encryption, too bad the computer will be felt Dianka! In addition, it can encrypt the film, worth a try.

c++ 写的加密算法，可以加密解密，采用的算法是比较长用的(c write the encryption algorithm, encryption can be decrypted using the algorithm is relatively long with the)
