Question about KeyDumperInterface

[lashae]

While trying to implement #429 I came across with the KeyDumperInterface:

interface KeyDumperInterface
{
    /**
     * Dumps a key to be shared between parties.
     *
     * @return resource|string
     */
    public function dumpKey();
}

All of the KeyLoaders included within the bundle implements this interface.

I searched the bundle for the usage of dumpKey() method however it seems that it isn't used anywhere. What is the purpose of this interface and required dumpKey method?

It has been added to ease sharing a public/shared key, see #305 for discussion.

Thank you for clarification.
