Bug fixes and Minor Issues

GCC 12 crash

cryptest.exe began experiencing crashes under GCC 12 and above. It appears GCC started removing live code. Building with GCC 12 and above now requires -fno-devirtualize option. See GH #1134 and GH #1141 for details.

CMake support

Abdessattar Sassi is now maintaining the CMake build system. Please visit abdes | cryptopp-cmake on GitHub.

Please note alternate build systems like Autotools and CMake are still not officially supported by the Crypto++ project. The project uses the makefile on Unix & Linux, and Visual Studio on Windows.

FIPS DLL deprecation

The FIPS DLL used to be an important artifact for Windows builds. NIST moved the Crypto++ library to the Historical Validation List in 2014. The Windows DLL is no longer validated.

The project files to build the FIPS DLL are cryptdll.vcxproj and dlltest.vcxproj. The projects are now deprecated and subject to removal.
