Versions

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

This package requires Node 8+ to work.

install

npm install buffer-crc32

example

1const crc32 = require('buffer-crc32');
2// works with buffers
3const buf = Buffer([0x00, 0x73, 0x75, 0x70, 0x20, 0x62, 0x72, 0x6f, 0x00]);
4crc32(buf); // -> <Buffer 94 5a ab 4a>
5
6// has convenience methods for getting signed or unsigned ints
7crc32.signed(buf); // -> -1805997238
8crc32.unsigned(buf); // -> 2488970058
9
10// will cast to buffer if given a string, so you can
11// directly use foreign characters safely
12crc32('自動販売機'); // -> <Buffer cb 03 1a c5>
13
14// and works in append mode too
15const partialCrc = crc32('hey');
16const partialCrc = crc32(' ', partialCrc);
17const partialCrc = crc32('sup', partialCrc);
18const partialCrc = crc32(' ', partialCrc);
19const 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 withnpm test (requires tap)
