I'm having trouble generating key pairs with init.js. When I run it, it will generate a key that says "undefined" and throw ENOENT errors telling me to unlink the temporary .key and .pub files.

Oh, my apologies! What OS and node/io version are you on?

The code is pretty minimal. You can throw some log statements in there to debug it yourself. Then commit the fix for others!

I opened an issue about this on Github and posted a workaround.

Now if only someone could accept my pull request :)
