I promised a new release of libobstcp today, but it's not going to happen I'm afraid - maybe Thursday. However, you do get a new draft:

Also, I've written an x86-64 version of curve25519. Previously, I had a C version that was under half the speed of djb's version. But djb's version was written in 32-bit asm, meaning that it couldn't link with 64-bit code. My 64-bit version is about 10% faster than djb's version. Source code coming soon.
