+*** 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 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.

+      the risk of reusing random numbers and IVs after virtual machine state
+      rollback
+    - changed default FIPS mode RNG from AutoSeededX917RNG<DES_EDE3> to
+      AutoSeededX917RNG<AES>
+    - fixed PANAMA cipher interface to accept 256-bit key and 256-bit IV
+    - moved MD2, MD4, MD5, PanamaHash, ARC4, WAKE_CFB into the namespace "Weak"
+    - removed HAVAL, MD5-MAC, XMAC
+
+5.5.1 - fixed VMAC validation failure on 32-bit big-endian machines
+
+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
+
+5.6.0 - added AuthenticatedSymmetricCipher interface class and Filter wrappers
+      - added CCM, GCM (with SSE2 assembly), EAX, CMAC, XSalsa20, and SEED
+      - added support for variable length IVs
+      - added OIDs for Brainpool elliptic curve parameters
+      - improved AES and SHA-256 speed on x86 and x64
+      - changed BlockTransformation interface to no longer assume data alignment
+      - 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
+      - fixed AES-CTR data alignment bug that causes incorrect encryption on ARM
+      - 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
+
+5.6.1 - added support for AES-NI and CLMUL instruction sets in AES and GMAC/GCM
+      - removed WAKE-CFB
+      - fixed several bugs in the SHA-256 x86/x64 assembly code:
+          * incorrect hash on non-SSE2 x86 machines on non-aligned input
+          * incorrect hash on x86 machines when input crosses 0x80000000
+          * incorrect hash on x64 when compiled with GCC with optimizations enabled
+      - fixed bugs in AES x86 and x64 assembly causing crashes in some MSVC build configurations
+      - switched to a public domain implementation of MARS
+      - ported to MSVC 2010, GCC 4.5.1, Sun Studio 12u1, C++Builder 2010, Intel C++ Compiler 11.1
+      - renamed the MSVC DLL project to "cryptopp" for compatibility with MSVC 2010

+The first 2 rounds and the last round seem especially vulnerable to timing
+attacks. The protection is similar to what was implemented for Rijndael.
+See comments at top of rijndael.cpp for more details.

+	A buffered transformation is an object that takes a stream of bytes

+	partial result already in the output buffer is not modified by further

+
+	If a method takes a "blocking" parameter, and you

+	In this case the method will return true
+	or a non-zero integer value. When this happens you must continue to call the method with the same
+	parameters until it returns false or zero, before calling any other method on it or
+	attached BufferedTransformation. The integer return value in this case is approximately
+	the number of bytes left to be processed, and can be used to implement a progress bar.
+
+	For functions that take a "propagation" parameter, propagation != 0 means pass on the signal to attached
+	BufferedTransformation objects, with propagation decremented at each step until it reaches 0.

+/*
+ * This is a major rewrite of my old public domain DES code written
+ * circa 1987, which in turn borrowed heavily from Jim Gillogly's 1977
+ * public domain code. I pretty much kept my key scheduling code, but
+ * the actual encrypt/decrypt routines are taken from from Richard
+ * Outerbridge's DES code as printed in Schneier's "Applied Cryptography."
+ *
+ * This code is in the public domain. I would appreciate bug reports and
+ * enhancements.

+/** \file
+
+	This file contains helper classes/functions for implementing public key algorithms.
+
+	The class hierachies in this .h file tend to look like this:
+<pre>
+                  x1
+                 / \
+                y1  z1

+                 |  |

+                 |  |
+                y3  z3
+</pre>
+	- x1, y1, z1 are abstract interface classes defined in cryptlib.h
+	- x2, y2, z2 are implementations of the interfaces using "abstract policies", which
+	  are pure virtual functions that should return interfaces to interchangeable algorithms.
+	  These classes have "Base" suffixes.
+	- x3, y3, z3 hold actual algorithms and implement those virtual functions.
+	  These classes have "Impl" suffixes.
+
+	The "TF_" prefix means an implementation using trapdoor functions on integers.
+	The "DL_" prefix means an implementation using group operations (in groups where discrete log is hard).

+/*
+Feb 2009: The x86/x64 assembly code was rewritten in by Wei Dai to do counter mode 
+caching, which was invented by Hongjun Wu and popularized by Daniel J. Bernstein 
+and Peter Schwabe in their paper "New AES software speed records". The round 
+function was also modified to include a trick similar to one in Brian Gladman's 
+x86 assembly code, doing an 8-bit register move to minimize the number of 
+register spills. Also switched to compressed tables and copying round keys to 
+the stack.
+
+The C++ implementation now uses compressed tables if 
+CRYPTOPP_ALLOW_UNALIGNED_DATA_ACCESS is defined.
+*/
+
+/*
+July 2006: Defense against timing attacks was added in by Wei Dai.
+
+The code now uses smaller tables in the first and last rounds,
+and preloads them into L1 cache before usage (by loading at least 
+one element in each cache line). 
+
+We try to delay subsequent accesses to each table (used in the first 
+and last rounds) until all of the table has been preloaded. Hopefully
+the compiler isn't smart enough to optimize that code away.
+
+After preloading the table, we also try not to access any memory location
+other than the table and the stack, in order to prevent table entries from 
+being unloaded from L1 cache, until that round is finished.
+(Some popular CPUs have 2-way associative caches.)

+/*! \file
+ 	This file contains helper classes for implementing stream ciphers.
+
+	All this infrastructure may look very complex compared to what's in Crypto++ 4.x,
+	but stream ciphers implementations now support a lot of new functionality,
+	including better performance (minimizing copying), resetting of keys and IVs, and methods to
+	query which features are supported by a cipher.
+
+	Here's an explanation of these classes. 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. This is done
+	by the ConceretePolicyHolder class. Finally, SymmetricCipherFinal implements the constructors and
+	other functions that must be implemented by the most derived class.

+ * The Whirlpool algorithm was developed by

+ *
+ * @version 3.0 (2003.03.12)
+ *
+ * =============================================================================
+ *
+ * Differences from version 2.1:
+ *
+ * - Suboptimal diffusion matrix replaced by cir(1, 1, 4, 1, 8, 5, 2, 9).
+ *
+ * =============================================================================
+ *
+ * Differences from version 2.0:
+ *
+ * - Generation of ISO/IEC 10118-3 test vectors.
+ * - Bug fix: nonzero carry was ignored when tallying the data length
+ *      (this bug apparently only manifested itself when feeding data
+ *      in pieces rather than in a single chunk at once).
+ * - Support for MS Visual C++ 64-bit integer arithmetic.
+ *
+ * Differences from version 1.0:
+ *
+ * - Original S-box replaced by the tweaked, hardware-efficient version.
