*** 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.
