## usage

```ts

import { assertEquals } from "https://deno.land/[email protected]/testing/asserts.ts";

import { Buffer } from "https://deno.land/[email protected]/node/buffer.ts";

import crc32 from "https://deno.land/x/buffer_crc32/mod.ts";

Deno.test("crc32", function() {

  const input = Buffer.from('hey sup bros');

  const expected = Buffer.from([0x47, 0xfa, 0x55, 0x70]);

  assertEquals(crc32(input), expected);

});
