From: Eneas U de Queiroz Date: Wed, 1 Aug 2018 13:59:13 +0000 (-0300) Subject: ustream-ssl: mbedtls: use chacha-poly ciphersuites X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=738e8d2489fc64f782affd1292388c66f6d69e82;p=oweals%2Fustream-ssl.git 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).
