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.
