Actually there's two parts. One is signing of tokens and the other is SSL.
SSL should be configurable as it's just a matter of configuring
undertow/WildFly underneath. Token signatures are at the moment hard coded
to bouncycastle.

Hi Ashkay, Stian and Marko,
This question helps me with something similar I asked yesterday. I enabled
strong ciphers in the JVM (JCE installed). However, when I switch SSL
logging on using "-Djavax.net.debug=ssl:handshake" I see that strong
ciphers on the ssl proxy (ECDHE) are not supported (therefore the message
Ignoring unsupported cipher suites).

Which ciphers are used by the Bouncycastle provider? Can I enable the use
of ECDHE ciphers? These ciphers are enabled in the ssl proxy:
ssl_ciphers
ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM
SHA256:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256;
Best regards, Bart

Afraid it's hardcoded to use Bouncycastle as the provider. You can open a
JIRA for it though.
