Gary,I looked at the code and you will need to use CryptoPP::HashTransformation instead of the old CryptoPP::HashModule which is defined in cryptlib.h it was a predecessor to HashTransformation in Crypto++ 4.2. I believe you are using Wei's latest Crypto++ 5.5.2 build in which HashModule has been deprecated. You mentioned in your email that your using Crypto++ 5.5.2 with Visual Studio so that kind of explains why your getting errors during the build process. I also see a class reference to FileSink you will need the proper include which is #include "files.h". As for compiling the libs, yes, I would suggest you compile the cryptlibd and cryptlib for your release and debug builds. Reference to HashTransformation: http://www.cryptopp.com/docs/ref/class_hash_transformation.html In response to another question posted on the group in which this topic came up. http://www.mail-archive.com/[email protected]/msg00101.html void DumpHash_SingleStep(CryptoPP::HashTransformation& hash, char const* szModuleName, std::string const& strData) { // Code } Moreover, the syntax errors are pretty straightforward. HexEncoder(new FileSink(cout)).Put(sbbDigest.Begin(), // sbbDigest.begin() See these topics and see if they help, I was able to compile this code using the proper version of the Crypto++ 4.2 http://www.linuxdiyf.com/viewarticle.php?id=109184 http://blog.csdn.net/violetfeeling/archive/2008/09/19/2949701.aspx I'm sure Mr. Dai will have more insightful information regarding HashModule and HashTransformation.
