Hi,
Thanks for the information.  How do I find out which plugin to try?

Hello,

That sounds like the plugin that provides those algorithms is broken.
You can try to work around that by making charon load another plugin, which provides the PRF algorithms for those signature algorithms, before the one you are using right now.
