打包文件，VB源码，还好，值得学习和使用.-Packing paper, VB source, Fortunately, it is worth learning and use.

是我设计的在DSB中隐藏语音的例子. 用ELANIX公司的SYSTEMVIEW打开运行. 其掩护信号和隐藏信号输入输出端均需设置语音源文件,比如自己录制的声音.-I designed the DSB concealed voice example. ELANIX company with the SYSTEMVI EW open operation. their cover and concealment signal input and output signals required to set up voice source, For example, recording their voices.

采用c++实现RC4加密解密算法，该代码可以加密解密任意格式的文件( U91C7 u758ccc_cn R U6587 u4EF6)

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：  DSA算法及验证，可用于license的制作(DSA algorithm and verification, which can be used in license making)

这个是编译通过的MD5算法，使用的语言是C++，非常好用。(MD5 C++ source code )
