Crypto benchmark is a tool for benchmarking modern AEAD algorithms.
Due to the use of the old AES-128-OCB algorithm and its slow implementation in Mumble, we decided to determine the best cipher and library for the VoIP communicator.
We build the project using Travis CI, on Ubuntu 18.04, using GCC and Clang compilers, on AMD64 and ARM64 platforms. Current status:
