If a constructor for A takes a pointer to an object B (except primitive +types such as int and char), then A owns B and will delete B at A's +destruction. If a constructor for A takes a reference to an object B, +then the caller retains ownership of B and should not destroy it until +A no longer needs it. + +2. Crypto++ is thread safe at the class level. This means you can use +Crypto++ safely in a multithreaded application, but you must provide +synchronization when multiple threads access a common Crypto++ object. + +*** MSVC-Specific Information *** + +On Windows, Crypto++ can be compiled into 3 forms: a static library +including all algorithms, a DLL with only FIPS Approved algorithms, and +a static library with only algorithms not in the DLL. +(FIPS Approved means Approved according to the FIPS 140-2 standard.) +The DLL may be used by itself, or it may be used together with the second +form of the static library. MSVC project files are included to build +all three forms, and sample applications using each of the three forms +are also included. + +To compile Crypto++ with MSVC, open the "cryptest.dsw" (for MSVC 6 and MSVC .NET +2003) or "cryptest.sln" (for MSVC .NET 2005) workspace file and build one or +more of the following projects: + +cryptdll - This builds the DLL. Please note that if you wish to use Crypto++ + as a FIPS validated module, you must use a pre-built DLL that has undergone + the FIPS validation process instead of building your own. +dlltest - This builds a sample application that only uses the DLL. +cryptest Non-DLL-Import Configuration - This builds the full static library + along with a full test driver. +cryptest DLL-Import Configuration - This builds a static library containing + only algorithms not in the DLL, along with a full test driver that uses + both the DLL and the static library. + +To use the Crypto++ DLL in your application, #include "dll.h" before including +any other Crypto++ header files, and place the DLL in the same directory as +your .exe file. dll.h includes the line #pragma comment(lib, "cryptopp") +so you don't have to explicitly list the import library in your project +settings. To use a static library form of Crypto++, specify it as +an additional library to link with in your project settings. +In either case you should check the compiler options to +make sure that the library and your application are using the same C++ +run-time libraries and calling conventions. + +*** DLL Memory Management *** + +Because it's possible for the Crypto++ DLL to delete objects allocated +by the calling application, they must use the same C++ memory heap. Three +methods are provided to achieve this. +1. The calling application can tell Crypto++ what heap to use. This method + is required when the calling application uses a non-standard heap. +2. Crypto++ can tell the calling application what heap to use. This method + is required when the calling application uses a statically linked C++ Run + Time Library. (Method 1 does not work in this case because the Crypto++ DLL + is initialized before the calling application's heap is initialized.) +3. Crypto++ can automatically use the heap provided by the calling application's + dynamically linked C++ Run Time Library. The calling application must + make sure that the dynamically linked C++ Run Time Library is initialized + before Crypto++ is loaded. (At this time it is not clear if it is possible + to control the order in which DLLs are initialized on Windows 9x machines, + so it might be best to avoid using this method.) + +When Crypto++ attaches to a new process, it searches all modules loaded +into the process space for exported functions "GetNewAndDeleteForCryptoPP" +and "SetNewAndDeleteFromCryptoPP". If one of these functions is found, +Crypto++ uses methods 1 or 2, respectively, by calling the function. +Otherwise, method 3 is used. + +*** GCC-Specific Information *** + +A makefile is included for you to compile Crypto++ with GCC. Make sure +you are using GNU Make and GNU ld. The make process will produce two files, +libcryptopp.a and cryptest.exe. Run "cryptest.exe v" for the validation +suite. + +*** Documentation and Support *** + +Crypto++ is documented through inline comments in header files, which are +processed through Doxygen to produce an HTML reference manual. You can find +a link to the manual from http://www.cryptopp.com. Also at that site is +the Crypto++ FAQ, which you should browse through before attempting to +use this library, because it will likely answer many of questions that +may come up. + +If you run into any problems, please try the Crypto++ mailing list. +The subscription information and the list archive are available on +http://www.cryptopp.com. You can also email me directly by visiting +http://www.weidai.com, but you will probably get a faster response through +the mailing list. + +*** History *** + +1.0 - First public release.
