PGP Software Development Kit Cryptographic Module  Operational Test Notes WHAT IS IT? ---------- The optest program is used as part of the FIPS 140-2 validation process. In particular, section  TE03.14.02  which requires that the tester shall perform each of the specified services and observe that that they have been implemented  properly.   As a side benefit to clients of the  SDK this code can also be used a good example of how to perform a number of commonly used functions, whether or not the developer intends to run in FIPS mode.   Depending on what option is chosen from the command line the following tests will be run: FIPS MODE SPECIFIC TESTS ------------------ - Invoke the Approved mode of operation (optest.c)     This involves Initializing the SDK, checking

对音频信号分帧加窗,对每帧进行三阶小波变换,取其逼近系数平均值(一般为零).在此嵌入二值图像 并有对潜入水印信号进行盲检,恢复其嵌入水印-Sub-frame of the audio signal increases the Hamming window for each frame impletment third-order wavelet transform, whichever is close to the average coefficient (usually zero). according to this embedding binary image and resume its embedded watermark from the watermark signal by the Blind detection

这是一个C的源代码，用来实现基于身份的加密算法-This is a C source code, used for identity-based encryption algorithm

修正了原CMd5类的CaculateStr函数的严重错误，并且转到新的C++类库。此类已经经过验证，文件和字符串均能得到正确结果，支持Unicode（Unicode时不需要转换）-amendment of the original CMd5 CaculateStr function of the type of serious errors and to the new C Class. Such has been validated, documents, and the string to get the correct result, Unicode support (Unicode does not need conversion)

参考了电脑爱好者2000第10期的一篇关于将文件隐藏于位图中的文章，本程序还有许多可以改进的地方，例如可以加入CRC校验，加密,多线程等内容。-reference to the 2000 resolution computer enthusiasts 10 of a document on Bitmap hidden in the article, there are many procedures can be improved, for example, can join the CRC, encryption, such as multithreading.
