port
Mandatory. TCP port number to open.
-%%
backlog
Maximum length of the pending connections queue. -%% Defaults to 1024.
-%%
ip
Interface to listen on. Listen on all interfaces -%% by default.
-%%
certfile
Mandatory. Path to a file containing the user's -%% certificate.
-%%
keyfile
Optional. Path to the file containing the user's -%% private PEM encoded key.
-%%
cacertfile
Optional. Path to file containing PEM encoded -%% CA certificates (trusted certificates used for verifying a peer -%% certificate).
-%%
password
Optional. String containing the user's password. -%% All private keyfiles must be password protected currently.
-%%
ciphers
Optional. The cipher suites that should be supported. -%% The function ssl:cipher_suites/0 can be used to find all available -%% ciphers.
