## listener.ssl.external.cacertfile = etc/certs/cacert.pem## The Ephemeral Diffie-Helman key exchange is a very effective way of
## ensuring Forward Secrecy by exchanging a set of keys that never hit
## the wire. Since the DH key is effectively signed by the private key,
## it needs to be at least as strong as the private key. In addition,
## the default DH groups that most of the OpenSSL installations have
## are only a handful (since they are distributed with the OpenSSL
## package that has been built for the operating system it’s running on)
## and hence predictable (not to mention, 1024 bits only).
## In order to escape this situation, first we need to generate a fresh,
## strong DH group, store it in a file and then use the option above,
## to force our SSL application to use the new DH group. Fortunately,
## OpenSSL provides us with a tool to do that. Simply run:
## openssl dhparam -out dh-params.pem 2048
##
## Value: File
## listener.ssl.external.dhfile = etc/certs/dh-params.pem## A server only does x509-path validation in mode verify_peer,

## More information at: http://erlang.org/doc/man/ssl.html
##
## Value: verify_peer | verify_none
## listener.ssl.external.verify = verify_peer## Used together with {verify, verify_peer} by an SSL server. If set to true,
## the server fails if the client does not have a certificate to send, that is,
## sends an empty certificate.
##
## Value: true | false
## listener.ssl.external.fail_if_no_peer_cert = true## This is the single most important configuration option of an Erlang SSL
## application. Ciphers (and their ordering) define the way the client and
## server encrypt information over the wire, from the initial Diffie-Helman
## key exchange, the session key encryption ## algorithm and the message
## digest algorithm. Selecting a good cipher suite is critical for the
## application’s data security, confidentiality and performance.
##
## The cipher list above offers:
##
## A good balance between compatibility with older browsers.
## It can get stricter for Machine-To-Machine scenarios.
## Perfect Forward Secrecy.
