-*** Important Usage Notes ***
-
-1. 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.

-      Whirlpool, and PANAMA cipher using assembly (x86-64, MMX, SSE2)
-    - optimized Camellia and added defense against timing attacks
-    - updated benchmarks code to show cycles per byte and to time key/IV setup

-
-5.5.2 - ported x64 assembly language code for AES, Salsa20, Sosemanuk, and Panama
-        to MSVC 2005 (using MASM since MSVC doesn't support inline assembly on x64)
-      - fixed Salsa20 initialization crash on non-SSE2 machines
-      - fixed Whirlpool crash on Pentium 2 machines
-      - fixed possible branch prediction analysis (BPA) vulnerability in
-        MontgomeryReduce(), which may affect security of RSA, RW, LUC
-      - fixed link error with MSVC 2003 when using "debug DLL" form of runtime library
-      - fixed crash in SSE2_Add on P4 machines when compiled with 
-        MSVC 6.0 SP5 with Processor Pack
-      - ported to MSVC 2008, GCC 4.2, Sun CC 5.9, Intel C++ Compiler 10.0, 
-        and Borland C++Builder 2007
-
-5.6 - added AuthenticatedSymmetricCipher interface class and Filter wrappers
-    - added CCM, GCM (with SSE2 assembly), EAX, CMAC, XSalsa20, and SEED
-    - added support for variable length IVs
-    - improved AES and SHA-256 speed on x86 and x64
-    - fixed incorrect VMAC computation on message lengths 
-      that are >64 mod 128 (x86 assembly version is not affected)
-    - fixed compiler error in vmac.cpp on x86 with GCC -fPIC
-    - fixed run-time validation error on x86-64 with GCC 4.3.2 -O2
-    - fixed HashFilter bug when putMessage=true
-    - removed WORD64_AVAILABLE; compiler support for 64-bit int is now required
-    - ported to GCC 4.3, C++Builder 2009, Sun CC 5.10, Intel C++ Compiler 11
