== Interesting links ==

* http://loup-vaillant.fr/articles/implementing-elligator * Relates to the obfs4/extra25519 deprecation. "There I was, implementing my own crypto, with nothing to compare to. No reference implementation, no test vectors, nothing. For use cases that are best justified when the stakes are frighteningly high."
