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 2005 - 2010) workspace file and build one or -more of the following projects: - -cryptopp - 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++, make the "cryptlib" -project a dependency of your application project, or 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.

The word "policy" is used here to mean a class with a - set of methods that must be implemented by individual stream cipher implementations. - This is usually much simpler than the full stream cipher API, which is implemented by - either AdditiveCipherTemplate or CFB_CipherTemplate using the policy. So for example, an - implementation of SEAL only needs to implement the AdditiveCipherAbstractPolicy interface - (since it's an additive cipher, i.e., it xors a keystream into the plaintext). - See this line in seal.h: - - typedef SymmetricCipherFinal\<ConcretePolicyHolder\<SEAL_Policy\<B\>, AdditiveCipherTemplate\<\> \> \> Encryption; - - AdditiveCipherTemplate and CFB_CipherTemplate are designed so that they don't need - to take a policy class as a template parameter (although this is allowed), so that - their code is not duplicated for each new cipher. Instead they each - get a reference to an abstract policy interface by calling AccessPolicy() on itself, so - AccessPolicy() must be overriden to return the actual policy reference.
