### Certificates

DDErl runs on SSL. A default certificate/key pair is [supplied](https://github.com/k2informatics/dderl/tree/master/priv/certs). This, however can be changed either by replacing these files at installation or modifying configuration in `ddConfig` table (`[{dderl,dderl,dderlSslOpts}]`). A sample configuration is given below:

```erlang

[{cert,<<48,...,107>>},

 {key,{'RSAPrivateKey',<<48,...,192>>}},

 {versions,['tlsv1.2','tlsv1.1',tlsv1]}]

```

[`erlang:ssl`](http://erlang.org/doc/man/ssl.html) describes all possible options above.

To convert a PEM crt/key files to DER (accepted by erlang SSL binary certificate/key option above) [`public_key:pem_decode/1`](http://www.erlang.org/doc/man/public_key.html#pem_decode-1) may be used as follows to obtain the DER binary of the PEM certificate files:

```erlang

> {ok, PemCrt} = file:read_file("server.crt").

{ok,<<"-----BEGIN CERTIFICATE-----\nMIICyTC"...>>}

> public_key:pem_decode(PemCrt).

[{'Certificate',<<48,130,2,201,48,130,2,50,2,9,0,241,25,...>>,not_encrypted}]

> {ok, PemKey} = file:read_file("server.key").

{ok,<<"-----BEGIN RSA PRIVATE KEY-----\nMIICXAI"...>>}

> public_key:pem_decode(PemKey).              

[{'RSAPrivateKey',<<48,130,2,92,2,1,0,2,129,129,0,160,95,...>>,not_encrypted}]

```
