I don't trust them. The various language bindings are maintained by random people who have gone through no particular vetting, and their code is not formally reviewed by anyone.

When I started looking through the node bindings, I found a number of minor bugs and a critical issue that left ~1% of passwords vulnerable.

I trust that the C developers do a good job, but phc-winner-argon2 does not appear to have ever made a formal release. Is master really always perfect?

It's not ready yet.
