From 738e8d2489fc64f782affd1292388c66f6d69e82 Mon Sep 17 00:00:00 2001 From: Eneas U de Queiroz Date: Wed, 1 Aug 2018 10:59:13 -0300 Subject: [PATCH] ustream-ssl: mbedtls: use chacha-poly ciphersuites These ciphersuites were added in mbedtls v2.12.0, so we may add them to the ustream-ssl ciphersuite list. They were already part of the list for openssl and wolfssl. Chacha20-Poly1305 is a 256-bit cipher with AEAD, much faster than AES on CPUs without special AES instructions (the case for most embedded chips).
