We can generate … TīmeklisIn this example, we generate fifteen random base-64 data pieces of different lengths. We set the minimum length to 8 and the maximum to 60. Since the length of base-64 is always a multiple of 4, the generated data is always either 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, or 60 characters long. doug tallamy\u0027s homegrown national park
