Overview

--------

This library is a utility module to help with point-compression techniques

for NIST P-256 and SEC-2 K-256 elliptic curve public keys. Refer to the

documentation (built using `make doc`) for more information.

Building

--------

Simply use `make` to build the library.

Limitations

-----------

This library only supports point-compaction for NIST P-256 keys and point

compression for SEC-2 K-256 keys. Other curves and compression combinations

could be supported, but the work has not yet been done. Contributions welcome.
