Function DoubleHashB

crypto/hash/hashfuncs.go:65–69

DoubleHashB calculates hash(hash(b)) and returns the resulting bytes.

(b []byte)

// DoubleHashB calculates hash(hash(b)) and returns the resulting bytes.
func DoubleHashB(b []byte) []byte {
	first := sha256.Sum256(b)
	second := sha256.Sum256(first[:])
	return second[:]
}

// DoubleHashH calculates hash(hash(b)) and returns the resulting bytes as a
// Hash.
