scrypt C library

I'm currently developing a C app in which I'll need to hash user's passwords. I know scrypt is currently one of the best methods to "hash" passwords (memory-bound, slow), but I can't seem to find a simple cross-pla开发者_StackOverflow社区tform C library that would do it for me.

And, since I'm neither a C expert or a cryptography/hashing expert, I'm afraid doing it myself will induce some obvious flaws in the system (it's easy to get these things wrong).

So, is there a C library that can do that, or, if not, other libraries that would implement similar solutions ? (bcrypt would work, although not as good as scrypt, ...)

Google says yes: scrypt_1.1.6.orig.tar.gz

(the relevant files seem to be in the lib subfolder)

this is an open source cross-platform library that has implementations of various crypto algorithms and hash functions from scratch.

You can see it here: https://github.com/kala13x/libxutils

In the examples directory, there is tool with name xcrypt which you can use as an example to see how lib functions are used. It's also a great tool for encrypting and decrypting files and text in CLI.
