Using TLS protocols v1.2+ with Arc

To enable Arc to use only TLS protocols (v1.2+) and ciphers that are known to be secure:

• TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256

• TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256

• TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384

• TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384

• TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305

• TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305

Open the settings.yml file located in the Arc installation directory and add the following parameter:

usesecuretls: true

Restart Arc.

More information about all settings can be found in the settings.sample.yml file available inside the Arc installation directory.
