That's a binding alright. But it's not easily installable: one has to install the scrypt library manually. I'm not sure how to do that because last time I checked scrypt is a program. Scrypt is also not packaged by Debian at this time. All in all, I think it's not the right time to use scrypt yet - at least not until there are easily installable libraries.
