Crypto++ 8.0

Crypto++ 8.0 was released on December 28, 2018. The 8.0.0 release was a major, planned release. There are no CVEs or memory errors.

This release was scheduled as a minor version bump, but we lost ABI compatibility due to adding AlgorithmProvider at PR 681.

Bug Fixes and Minor Issues

The bug fix and minor issue list for Crypto++ 8.0 follows. Many non-trivial issues are tracked for auditing and C&A purposes, but the list may not be complete. A number in parenthesis is the GitHub Issue number, if it was tracked. Sometimes a Git commit is referenced, but many trivial GitHub commits are omitted.

MinGW 32-bit

MinGW 32-bit is failing self tests for LEA, SIMON, SPECK and SM4. MinGW 64-bit is OK. We don't know the cause and don't have a work-around.

We are tracking the problem at Issue 768, 32-bit MinGW self test failures.

Sockets and threads

Crypto++ removed Operating System specific code for sockets and threads. OS specific socket and thread support was removed to streamline the library and focus on the cryptography. The removal will also avoid porting troubles which surface on occassion. Users can re-install the files or utilize C++11 support, if desired.

The list of files removed are as follows.

  • network.cpp
  • network.h
  • socketft.cpp
  • socketft.h
  • trdlocal.cpp
  • trdlocal.h
  • wait.cpp
  • wait.h
  • winpipes.cpp
  • winpipes.h

A wiki page was setup to document the change and provide the old source files at Sockets and Threads.

setenv-android.sh

The cross-compile script setenv-android.sh is no longer viable for building the library using the Android NDK. Recent NDK changes has mostly obsoleted the script. We are moving to a new script but it is not ready at the moment. Also see Issue 763, Building for Android using NDK not supported on Windows hosts.

We have a GitHub setup with yet another build system at cryptopp-android. It provides Android.mk for Android's build system.
