rabbitmq cipher suites issues beginning with erlang 24.1

[rgoerner]

Hi,

I was just running in an issue on our labs while testing some latest releases.

With rabbitmq 3.9.x and erlang 24.0.6 and before, the settings

                {rsa,aes_256_cbc,sha},
                {rsa,aes_128_cbc,sha},

for cipher-suites are working well.

Beginning with erlang 24.1, those settings are ignored and the ciphersuites are not available on connecting to rabbitmq,

If you list the supported ciphers:

rabbitmq-diagnostics cipher_suites --format erlang -q | grep cbc

both, on erlang 24.0 and 24.1, they are supported. But with erlang 24.1, not available anymore when connecting.

Is this an issue with rabbitmq, or erlang? I am confused.

Thanks
Ronny

I will convert this issue to a GitHub discussion. Currently GitHub will automatically close and lock the issue even though your question will be transferred and responded to elsewhere. This is to let you know that we do not intend to ignore this but this is how the current GitHub conversion mechanism makes it seem for the users :(
