See 10 http://www.secg.org/collateral/sec2_final.pdf for details on the 11 standard. 12 13 This package provides the data structures and functions implementing the 14 crypto/elliptic Curve interface in order to permit using these curves 15 with the standard crypto/ecdsa package provided with go. Helper 16 functionality is provided to parse signatures and public keys from 17 standard formats. It was designed for use with btcd, but should be 18 general enough for other uses of elliptic curve crypto. It was originally based 19 on some initial work by ThePiachu, but has significantly diverged since then. 20 */ 21 package btcecv1
