What programming language are you using? If you are using php - http://php.net/manual/en/function.crc32.php - http://www.php.net/manual/en/function.hash.php

Yes, using php
Some code:

if (isset($_POST['send_icon'])){
    $fileName=$_FILES["icon"]["name"];
    $fileSize=(float) (($_FILES["icon"]["size"]) / 1024);
    $fileCRC32=crc32($_FILES["icon"]["tmp_name"]);

Each time get different values of crc32)

Isn't your 'tmp_name' changing? You should get crc from whole file not just name.

Oh, yes, tmp_name os changing.
Will calculate with ready file.

Solved.
For successful calcuting need:

$pathIcon="/path/to/icon";
$fileContent=file_get_contents($pathIcon);
$crc32=crc32($fileContent);
