SHA256 + Curve25519 C or Objective-C for Mac OS X

Need a C or Objective C program that I can run in XCode IDE on Mac that takes a passphrase and hashes it using SHA256 to derive a private key and the private key is encrypted using Curve25519 to derive the public key. It must be super fast. That is why I want it in C. It must work on Mac I must be able to run it from XCode. Upon successful delivery I might need a bit more around it.
