检测CRC编码 看CRC编码在传输后是否有错误 有变动 (Detection CRC codes to see whether the CRC coding errors in the transmission there is a change)

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)

VB6.0调用Windows系统的API计算MD5码。这个代码跟网上流行的代码相比，具有代码简洁，维护方便，运行效率高等优点。运行速度比用纯VB6实现的快得多。(VB6.0- Call Windows system API calculate MD5 code. This code is compared with the popular online code, with code simple, easy maintenance, high efficiency. Runs faster than pure VB6 realize faster.)

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 !)

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)

使用dll，将vc下进行文件加解密的blowfish方法做成dll文件，从而在vc中调用，隐藏加解密的参变量。(Using dll, under the vc the blowfish file encryption method made dll file, so call in vc, the hidden variable encryption and decryption of the parameters.)

自己写的一份RSA算法。可正常执行。控制台程序。(Write your own copy of the RSA algorithm. Can be performed normally. Console program.)

支持加密Sqllite库，vs2008 + sqlite3 + sqlcipher,测试可用(Supports encryption Sqllite library, VS2008+ SQLite3+ sqlcipher, testing available)

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.)

RC4解加密算法生成DLL动态库，密钥可以再程序里面写死或者外部导入！(The RC4 the Xie encryption algorithm to generate the DLL dynamic libraries, key can re-program inside hardcoded or external import!)
