libsecp256k1
============

Optimized C library for EC operations on curve secp256k1
Optimized C library for EC operations on curve secp256k1.

This library is experimental, so use at your own risk.

Features:
* Low-level field and group operations on secp256k1.
* ECDSA signing/verification and key generation.
* Adding/multiplying private/public keys.
* Serialization/parsing of private keys, public keys, signatures.
* Very efficient implementation.

Implementation details

* Point multiplication for signing
* Use a precomputed table of multiples of powers of 16 multiplied with the generator, so general multiplication becomes a series of additions.
* Slice the precomputed table in memory per byte, so memory access to the table becomes uniform.
* Not fully constant-time.
