generate random bytes in go

func GenRandomBytes(size int) (randomBytes []byte) {
    rand.Seed(time.Now().UnixNano())
    randomBytes = make([]byte, size)
    rand.Read(randomBytes)
    return randomBytes
}

Context

Pay attention to this line, otherwise everytime randomBytes is the same.

rand.Seed(time.Now().UnixNano())
