The Crypto++ library was orginally written by Wei Dai. The library is now
maintained by several team members and the community. You are welcome to use it
for any purpose without paying anyone, but see License.txt for the fine print.
The following compilers are supported for this release. Please visit
http://www.cryptopp.com the most up to date build instructions and porting notes.
* Visual Studio 2003 - 2015
* GCC 3.3 - 7.1
* Apple Clang 4.3 - 8.3
* LLVM Clang 2.9 - 4.0
* C++Builder 2010
* Intel C++ Compiler 9 - 16.0
* Sun Studio 12u1 - 12.5
*** 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 ***
To compile Crypto++ with MSVC, open "cryptest.sln" (for MSVC 2003 - 2015)
and build one or more of the following projects:
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.
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.
The DLL used to provide FIPS validated cryptography. The library was moved
to the CMVP's <A HREF=
"http://csrc.nist.gov/groups/STM/cmvp/documents/140-1/140val-historical.htm">
Historical Validation List</A>. The library and the DLL are no longer considered
validated. You should no longer use the DLL.
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.
*** Linux and Unix-like Specific Information ***
A makefile is included for you to compile Crypto++ with GCC and compatibles.
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 and "cryptest.exe tv all" for additional test vectors.
The makefile uses '-DNDEBUG -g2 -O2' CXXFLAGS by default. If you use an
alternate build system, like Autotools or CMake, then ensure the build system
includes '-DNDEBUG' for production or release builds. The Crypto++ library uses
asserts for debugging and diagnostics during development; it does not
rely on them to crash a program at runtime.
If an assert triggers in production software, then unprotected sensitive
information could be egressed from the program to the filesystem or the
platform's error reporting program, like Apport on Ubuntu or CrashReporter
on Apple.
The makefile orders object files to help remediate problems associated with
C++ static initialization order. The library does not use custom linker scripts.
If you use an alternate build system, like Autotools or CMake, and collect source
files into a list, then ensure these three are at the head of the list: 'cryptlib.cpp
cpu.cpp integer.cpp <other sources>'. They should be linked in the same order:
'cryptlib.o cpu.o integer.o <other objects>'.
If your linker supports initialization attributes, like init_priority, then you can
define CRYPTOPP_INIT_PRIORITY to control object initialization order. Set it to a
value like 250. User programs can use CRYPTOPP_USER_PRIORITY to avoid conflicts with
library values. Initialization attributes are more reliable than object file ordering,
but its not ubiquitously supported by linkers.
The makefile links to the static version of the Crypto++ library to avoid binary
planting and other LD_PRELOAD tricks. You should use the static version of the
library in your programs to help avoid unwanted redirections.
*** 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. Finally, the site provide the wiki which has many topics
and code examples.
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.
*** Source Code and Contributing ***
The source code and its planned changes are available at the following locations.
* The Crypto++ GitHub repository allows you to view the latest (unreleased)
Crypto++ source code via the Linux kernel's git beginning around June 2015.
Its also serves as an incubator to nuture and grow the library.
* The former Crypto++ SourceForge repository allows you to view the Crypto++
source code via Apache's subversion until about July 2015. At that time,
SourceForge had infrastructure problems and a cutover to GutHub was performed.
* The Roadmap on the wiki provides the general direction the library is heading.
It includes planned features and releases, and even some wishlist items.
Contributions of all types are welcomed. Contributions include the following.
* Bug finding and fixes
* Features and enhancements
* Test scripts and test cases
* Branch and release testing
* Documentation and updates
If you think you have found a bug in the library, then you should discuss it on the
Users mailing list. Discussing it will help bring the issue to the attention of folks
who can help resolve the issue. If you want to contribute a bug fix to the library,
then make a Pull Request or make a Diff available somewhere. Also see Bug Reports on
the wiki.
Features and enhancements are welcomend additions to the library. This category tends
to be time consuming because algorithms and their test cases need to be reviewed and
merged. Please be mindful of the test cases, and attempt to procure them from an
independent source.
The library cherishes test scripts and test cases. They ensure the library is fit and
they help uncover issues with the library before users experience them. If you have
some time, then write some test cases, especially the ones that are intended to break
things.
Branch and release testing is your chance to ensure Master (and planned merges) meets
your expectations and perform as expected. If you have a few spare cycles, then please
test Master on your favorite platform. We need more testing on MinGW, Windows Phone,
Windows Store, Solaris 10 (and below), and modern iOS and OS X (including TV and
Watch builds).
Documentation and updates includes both the inline source code annotations using
Doxygen, and the online information provided in the wiki. The wiki is more verbose and
usually provides more contextual information than the API reference. Besides testing,
documentation is one of the highest returns on investment.
