// Package btcec implements support for the elliptic curves needed for bitcoin.
//
// Bitcoin uses elliptic curve cryptography using koblitz curves
// (specifically secp256k1) for cryptographic functions.  See
// http://www.secg.org/collateral/sec2_final.pdf for details on the
// standard.
//
// This package provides the data structures and functions implementing the
// crypto/elliptic Curve interface in order to permit using these curves
// with the standard crypto/ecdsa package provided with go. Helper
// functionality is provided to parse signatures and public keys from
// standard formats.  It was designed for use with btcd, but should be
// general enough for other uses of elliptic curve crypto.  It was originally based
// on some initial work by ThePiachu, but has significantly diverged since then.
