Using TLS 1.3 with Phoenix

[Elmiira]

@voltone

{:ok, listen_socket} = :ssl.listen(8080, [{:certfile, “server.crt”}, {:keyfile, “server.key”}, {:cacertfile, “ca.crt”}, {:reuseaddr, true}, {:versions, [:‘tlsv1.3’]}, ciphers: [%{cipher: :aes_gcm, prf: :sha384}]])

Thanks, right,
After fixing to :
{:ok, listen_socket} = :ssl.listen(8080, [{:certfile, "server.crt"}, {:keyfile, "server.key"}, {:cacertfile, "ca.crt"}, {:reuseaddr, true}, {:versions, [:'tlsv1.3']}, ciphers: [%{cipher: :chacha20_poly1305, prf: :sha384}]])

the error is:

(MatchError) no match of right hand side value: {:error, {:options, {:insufficient_crypto_support, {:"tlsv1.3", {:versions, [:"tlsv1.3"]}}}}}
     code: tls_start()

the one that exactly i receive in my real application.
