# erlang-tls-misc
Miscellaneous Erlang TLS examples.
## Resources
https://erlef.github.io/security-wg/secure_coding_and_deployment_hardening/ssl.html
https://elixirforum.com/t/ssl-with-tortoise-lib-not-working/18256/4
https://github.com/vernemq/vernemq/issues/1485
https://github.com/hexpm/hex/pull/798
## Prerequisites
* `bash` version 4 or higher (tested with `5.0.18`)
* `git` (tested with `2.29.2`)
* `sed` (tested with GNU version `4.8`)
* `python` (tested with `3.8.6`)
* `openssl` (tested with `1.1.1h`)
* `erl` (tested with `23.1.2`)
## TLS-encrypted distribution usage
* Set up environment and certificates:
```
./setup.sh
```
* Run node a in one terminal:
```
./run-node-a.sh
```
* Run node b in another terminal:
```
./run-node-b.sh
```
## Expected output:
```
$ ./run-node-b.sh
Erlang/OTP 23 [erts-11.1.2] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1] [hipe]
Eshell V11.1.2 (abort with ^G)
(b@shostakovich)1> ['a@shostakovich']
(b@shostakovich)1> nodes().
[a@shostakovich]
(b@shostakovich)2> init:stop().
ok
(b@shostakovich)3>
```
## TLS client usage
* Setup Python environment:
```
./setup-py.sh
```
* Start RabbitMQ:
```
make RABBITMQ_CONFIG_FILE="/home/lbakken/development/lukebakken/erlang-tls-misc/rabbitmq-tls.config" PLUGINS='rabbitmq_management rabbitmq_top' LOG=debug run-broker
```
* Run Python client:
```
source venv/bin/activate
python ./tls-client.py
```
RabbitMQ log should have entries like these:
```
