Documentation

Overview

Package doublehash implements double hashing via a hash.Hash.

Index

• func New(inner, outer crypto.Hash) hash.Hash
• func NewHash(inner, outer hash.Hash) hash.Hash

Functions

func New

func New(inner, outer crypto.Hash) hash.Hash

New returns a new hash.Hash that computes a double hash. The hashes are specified by name, e.g. crypto.SHA256.

func NewHash

func NewHash(inner, outer hash.Hash) hash.Hash

NewHash returns a new hash.Hash that computes a double hash.

func SumDoubleSha256

func SumDoubleSha256(data []byte) [sha256.Size]byte

SumDoubleSha256 is a convience function that returns the double sha256 hash of the data.

func SumSha256Ripemd160

func SumSha256Ripemd160(data []byte) (sum160 [ripemd160Size]byte)

SumSha256Ripemd160 is a convience function that returns the ripemd160 hash of the sha256 hash of the data. SumSha256Ripemd160 panics if the crypto.RIPEMD160 hash is not linked into the binary.
