Disabling TLS 1.1 is (as of August 2016) mostly optional; TLS 1.2 provides stronger encryption options, but 1.1 is not yet known to be broken. Disabling 1.1 may mitigate attacks against some broken TLS implementations.

RFC 8439: ChaCha20 and Poly1305 for IETF Protocols

ChaCha20-Poly1305 is an authenticated encryption with additional data (AEAD) algorithm, that combines the ChaCha20 stream cipher with the Poly1305 message authentication code. Its usage in IETF protocols is standardized in RFC 8439. It has fast software performance, and without hardware acceleration, is usually faster than AES-GCM. WebFor example: $ openssl s_server -cert mycert.pem -key mykey.pem -cipher ECDHE -ciphersuites "TLS_AES_256_GCM_SHA384:TLS_CHACHA20_POLY1305_SHA256" This will configure OpenSSL to use any ECDHE based ciphersuites for TLSv1.2 and below.
