Hello, I have two servers for testing purpose : - debian 6, apache 2.2, openssl 1.0.1t (mutu) - centos 7, apache 2.4.6, openssl 1.0.1e-fips (dedicated) Now, these 2 serveurs offers only those ciphers : TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 (0xc030) TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384 (0xc028) TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA (0xc014) I have two goals. First, I would like to use at least secp384r1 and second (no problem), use an ECC certificate. Is it possible to do it with CHACHA20-POLY1305 ? Is it possible to use this cipher on those servers ? openssl ciphers -V CHACHA20 return an error on each server. I understand it's because there is no chacha20 cipher (?). Why can I connect a server by SSH with chacha20-poly1305@xxxxxxxxxxx and not using it with Apache ? All advices are welcome :-).
