Golang crypto_hash Examples

Example #1

File: cryptonacl.go Project: nimbus-network/nimbus-desktop

func Hash(message []byte) []byte {
	hash := make([]byte, HashSize)

	C.crypto_hash(array(hash), array(message), C.ulonglong(len(message)))

	return hash
}

Example #2

File: crypto_hash.go Project: enlumox/libsodium-go

func CryptoHash(in []byte) ([]byte, int) {
	out := make([]byte, CryptoHashBytes())
	exit := int(C.crypto_hash(
		(*C.uchar)(&out[0]),
		(*C.uchar)(&in[0]),
		(C.ulonglong)(len(in))))

	return out, exit
}

Example #3

File: hash.go Project: jaked122/Sia

// Uses the hash in libsodium
func CalculateHash(data []byte) (hash Hash, err error) {
	hashPointer := (*C.uchar)(unsafe.Pointer(&hash[0]))
	messagePointer := (*C.uchar)(unsafe.Pointer(&data[0]))
	sizeOfMessage := C.ulonglong(len(data))
	success := C.crypto_hash(hashPointer, messagePointer, sizeOfMessage)
	if success != 0 {
		err = fmt.Errorf("Error in calculating hash")
	}

	return
}
