SFCMC is a high-performance, compact simple cryptor.
Key features:
- Super high-performance (faster than chacha20)
- Super simple and easy
- Easy change of parameters for experiments
- Easily optimized for multithreading and new hardware architectures
- Passed tests from NIST SP 800-22 Statistical Test Suite.
Encryption speed: ~5%-20% faster than ChaCha20
Entropy: =8.00000 bits/byte stable
Autocorellation: ~0.0000 (0.0004 max)
Intel Xeon E5-2670 v2 (single core) CFCMC and ChaCha20 builded in one application for testing without optimizations. compiler LLVM 142
