VB文件加密器（异或加密）,有需要的就下载吧。(VB file encryption (XOR encryption), there is a need to download it.)

仿射 suanfa daima 加密 解密(affine suanfa daima affine )

C++ implementation for S26

说明：  用visual c++ 写的des加密算法演示 (with visual c write des encryption algorithm demo)

整体思路 用createkey.java 文件来产生秘钥，用jiami.java 文件来实 现加密，用jiemi.java 文件来实现解密,用BigInteger.java 来实现 大数的表示及运算，用rsa.java 来实现前端图形界面显示。有关函 数见五个文件里的具体实现。 (The overall outlook createkey.java document used to generate secret keys, used to achieve jiami.java file encryption, used to achieve jiemi.java documents declassified by BigInteger.java to achieve expression of large numbers and calculations, using rsa.java to achieve front-end graphical interface display. Related functions, see the five concrete realization of the document.)

3Des encryption of text from a file, 3DES-EDC-CBC , using 3 keys

文件的加密传输，用到了各种加密算法 MD5 RSA (File encryption MD5 RSA )

文件加密使用,可以实现对PC上文件进行加密解密功能(document encryption use, the PC can be achieved on the document encryption and decryption functions)

GOST加密解密程序，源代码是在控制台下的，我只是把他改写成MFC了。方便操作。加密解密高手可以绕过。(The GOST encryption and decryption procedures, the source code is under the console, I just put him rewrite the MFC. Easy to operate. Encryption and decryption master can be bypassed.)

今天我们学习了des对称加密算法这是一个des算法的C++实现(This is a des !)
