+# crc32-stream v2.0.0 [![Build Status](https://travis-ci.org/archiverjs/node-crc32-stream.svg?branch=master)](https://travis-ci.org/archiverjs/node-crc32-stream) [![Build status](https://ci.appveyor.com/api/projects/status/sy60s39cmyvd60i3/branch/master?svg=true)](https://ci.appveyor.com/project/ctalkington/node-crc32-stream/branch/master)
+
+crc32-stream is a streaming CRC32 checksumer. It uses [buffer-crc32](https://www.npmjs.org/package/buffer-crc32) behind the scenes to reliably handle binary data and fancy character sets. Data is passed through untouched.
+
+### Install
+
+```bash
+npm install crc32-stream --save
+```
+
+You can also use `npm install https://github.com/archiverjs/node-crc32-stream/archive/master.tar.gz` to test upcoming versions.
+
+### Usage
+
+#### CRC32Stream
+
+Inherits [Transform Stream](http://nodejs.org/api/stream.html#stream_class_stream_transform) options and methods.
+
+```js
+var CRC32Stream = require('crc32-stream');
+
+var source = fs.createReadStream('file.txt');
+var checksum = new CRC32Stream();
+
+checksum.on('end', function(err) {
+  // do something with checksum.digest() here
+});
+
+// either pipe it
+source.pipe(checksum);
+
+// or write it
+checksum.write('string');
+checksum.end();
+```
+
+#### DeflateCRC32Stream
+
+Inherits [zlib.DeflateRaw](http://nodejs.org/api/zlib.html#zlib_class_zlib_deflateraw) options and methods.
+
+```js
+var DeflateCRC32Stream = require('crc32-stream').DeflateCRC32Stream;
+
+var source = fs.createReadStream('file.txt');
+var checksum = new DeflateCRC32Stream();
+
+checksum.on('end', function(err) {
+  // do something with checksum.digest() here
+});
+
+// either pipe it
+source.pipe(checksum);
+
+// or write it
+checksum.write('string');
+checksum.end();
+```
+
+### Instance API
+
+#### digest()
+
+Returns the checksum digest in unsigned form.
+
+#### hex()
+
+Returns the hexadecimal representation of the checksum digest. (ie E81722F0)
+
+#### size(compressed)
+
+Returns the raw size/length of passed-through data.
+
+If `compressed` is `true`, it returns compressed length instead. (DeflateCRC32Stream)
