Package sha3 implements the SHA3 hash algorithm (formerly called Keccak) chosen by NIST in 2012.

Creates an ethereum address given the bytes and the nonce.

HexToECDSA parses a secp256k1 private key.

Used only by block tests.

creates a Key and stores that in the given KeyStore by decrypting a presale key JSON.

TODO: See if we can refactor this into a shared util lib if we need it multiple times.

LoadECDSA loads a secp256k1 private key from the given file.

S160 returns a BitCurve which implements secp160k1 (see SEC 2 section 2.4.1).

S192 returns a BitCurve which implements secp192k1 (see SEC 2 section 2.5.1).

S224 returns a BitCurve which implements secp224k1 (see SEC 2 section 2.6.1).

S256 returns a BitCurve which implements secp256k1 (see SEC 2 section 2.7.1).

SaveECDSA saves a secp256k1 private key to the given file with restrictive permissions.

New methods using proper ecdsa keys from the stdlib.

A BitCurve represents a Koblitz Curve with a=0.
