 Crypto++ Library is a free C++ class library of cryptographic algorithms and schemes. It was written and placed in public domain by Wei Dai. The library homepage is at http://www.cryptopp.com/. The latest library source code can be found at https://github.com/weidai11/cryptopp. For licensing and copyright information, please see License.txt.

+These are general instructions for the BSDs, Linux, OS X, Solaris and Unix. On BSD you will likely have to use `gmake` to build the library. On Linux, OS X, Solaris and Unix, the system's make should be OK. On Windows, Crypto++ provides Borland and Visual Studio solutions.
 
 Crypto++ uses a GNU makefile, which combines configuration and a non-anemic make. You should look through the GNUmakefile and config.h to ensure settings look reasonable before building. Please pay particular attention to CRYPTOPP_NO_UNALIGNED_DATA_ACCESS in config.h.
