> The libsec-chacha.diff patch is not useful, since it's not used yet. Just to clarify. The libsec-chacha.diff patch implements ChaCha20 stream cipher in libsec. It was developped by Charles Forsyth. (https://bitbucket.org/plan9-from-bell-labs/plan9).
To make use of it, you have to implement Poly1305 algorithm in libsec and change devtls and tlshand to support ChaCha20 and Poly1305. These changes are already available as part of 9front. -- David du Colombier
