Crypto++ 8.2

Crypto++ 8.2 was released on April 28, 2019. The 8.2 release was a minor, unplanned release. There are no CVEs or memory errors.

Two bugs were cleared that could cause discomfort for users. First, PowerPC switched from Power7 to Power8 for unaligned loads and stores. The bug affected Debian users on some PowerPC machines. Second, SHAKE-128 and SHAKE-256 constructors were fixed. The bug affected older GCC and some other compilers.


The download is available from the Crypto++ website. The checksums for the download are below. Release signatures can be verified using GnuPG according to Release Signing.

Mirrors for the download are below. Note that GitHub checksums on the ZIP or TAR are different because the service creates the archive from sources.

Bug fixes and Minor Issues

The bug fix and minor issue list for Crypto++ 8.2 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. Missing Issue numbers or lack of consecutiveness usually indicates feature requests and "won't fix/can't fix" type reports.


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.

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.
