curve25519-donna: Curve25519 elliptic curve, public key function
http://code.google.com/p/curve25519-donna/
Adam Langley <[email protected]>
Derived from public domain C code by Daniel J. Bernstein
More information about curve25519 can be found here
http://cr.yp.to/ecdh.html
djb's sample implementation of curve25519 is written in a special
assembly language called qhasm and uses the floating point registers.
This is, almost, a clean room reimplementation from the curve25519
paper. It uses many of the tricks described therein. Only the crecip
function is taken from the sample implementation.
