Package bn256 implements the Optimal Ate pairing over a 256-bit Barreto-Naehrig curve.

CompressPubkey encodes a public key to the 33-byte compressed format.

CreateAddress creates an ethereum address given the bytes and the nonce.

CreateAddress2 creates an ethereum address given the address bytes, initial contract code hash and a salt.

DecompressPubkey parses a public key in the 33-byte compressed format.

Ecrecover returns the uncompressed public key that created the given signature.

FromECDSA exports a private key into a binary dump.

HexToECDSA parses a secp256k1 private key.

Keccak256 calculates and returns the Keccak256 hash of the input data.
