+# buffer-crc32
+
+[![Build Status](https://secure.travis-ci.org/brianloveswords/buffer-crc32.png?branch=master)](http://travis-ci.org/brianloveswords/buffer-crc32)
+
+crc32 that works with binary data and fancy character sets, outputs
+buffer, signed or unsigned data and has tests.
+
+Derived from the sample CRC implementation in the PNG specification: http://www.w3.org/TR/PNG/#D-CRCAppendix
+
+# install
+```
+npm install buffer-crc32
+```
+
+# example
+```js
+var crc32 = require('buffer-crc32');
+// works with buffers
+var buf = Buffer([0x00, 0x73, 0x75, 0x70, 0x20, 0x62, 0x72, 0x6f, 0x00])
+crc32(buf) // -> <Buffer 94 5a ab 4a>
+
+// has convenience methods for getting signed or unsigned ints
+crc32.signed(buf) // -> -1805997238
+crc32.unsigned(buf) // -> 2488970058
+
+// will cast to buffer if given a string, so you can
+// directly use foreign characters safely
+crc32('自動販売機') // -> <Buffer cb 03 1a c5>
+
+// and works in append mode too
+var partialCrc = crc32('hey');
+var partialCrc = crc32(' ', partialCrc);
+var partialCrc = crc32('sup', partialCrc);
+var partialCrc = crc32(' ', partialCrc);
+var finalCrc = crc32('bros', partialCrc); // -> <Buffer 47 fa 55 70>
+```
+
+# tests
+This was tested against the output of zlib's crc32 method. You can run
+the tests with`npm test` (requires tap)
+
+# see also
+https://github.com/alexgorbatchev/node-crc, `crc.buffer.crc32` also
+supports buffer inputs and return unsigned ints (thanks @tjholowaychuk).
