Module aead

AEAD

Depending on the platform and available features the most efficient implementation is chosen.

ChaCha20Poly1305

The HACL implementations are used on all platforms. On x64 CPUs with AVX and AVX2 support the 256-bit SIMD implementation is used. On CPUs with a 128-bit SIMD unit (arm64, or SSE3, SSE4.1, and AVX on x64), the 128-bit SIMD implementation is used. In any other case the portable implementation is used.
