/**
* Decompress the GZIP compressed data (returning null on error).
* @throws IOException if uncompressed is over 40 KB,
* or on a decompression error
* @return null if orig is null
*/
public static byte[] decompress(byte orig[]) throws IOException {
return (orig != null ? decompress(orig, 0, orig.length) : null);
}

/**
* pull the unencrypted AND DECOMPRESSED data

// future - check magic number to see whether to decompress

if (_log.shouldWarn())

return null;
}
}
return compressed;
