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.
