Erlang/OTP 20.3

Posted 2018-03-14 19:00:53.000000

I love paging through the release notes of new Erlang/OTP releases, especially the sections for the ssl, public_key and crypto applications. So I spent a few minutes today looking at what’s new in today’s OTP 20.3. There doesn’t seem to be anything new in public_key or crypto this time around, so let’s have a quick look at ssl.

SSL

Apart from some fixes to anonymous cipher suite handling, contributed by yours truly :), and further DTLS improvements I noticed some new APIs for filtering and reordering cipher suites:

• filter_cipher_suites/2
• append_cipher_suites/2
• prepend_cipher_suites/2

They are a nice enhancement, but I won’t be retiring my cipher_suites package just yet: I believe there is value in making OpenSSL cipher selection expressions available in Erlang/Elixir, because they are more expressive and more ubiquitous.
