Use Composer to solve ID encryption problem: Application of ctfang/id-to-code library

Install

Installing ctfang/id-to-code using Composer is very simple, just run the following command:

 <code class="language-bash">composer require ctfang/id-to-code</code>

use

First, we need to generate an encryption template. The following code can be used to generate and save the template:

 <code class="language-php"><?php use IdCode\CodeGen;
use IdCode\CodeService;

require_once __DIR__."/../src/CodeService.php";
require_once __DIR__."/../src/CodeGen.php";

// 最短长度
$minLen = 8;
// 数字长度位 纯数字模式
$mode   = CodeService::numMode;
// 字符长度位 纯数字模式
// $mode   = CodeService::chrModel;
// 无长度位 36进制| 不能设置最短位数,但是能在最短的位数表达更大的数量
// $mode   = CodeService::notMode;

if ( !file_exists('int.config.json') ){
    file_put_contents('int.config.json',(new CodeGen())-> genKey($minLen,$mode)); }</code>

After generating the template, we can use CodeService to encrypt and decrypt the ID. Here is an example showing how to encrypt and decrypt 100 million IDs:

 <code class="language-php"><?php use IdCode\CodeService;

$code = new CodeService('int.config.json');

$ok = true;
// 加密解密一亿次
for ($int=0;$int<100000000;$int  ){
    $base = $int;
    $str = $code-> toString($int); $newInt = $code->toInt($str); if ($base != $newInt){ $ok = false; break; } } if ($ok){ var_dump("加密和解密正常"); }; var_dump($code->toString(1));</code>

Each integer ID is converted into a code similar to 71869931 .

principle

ctfang/id-to-code library is very fast by replacing numbers with encryption templates instead of hashing. An encryption template is a mapping table generated by anti-human habits. After the template is converted, ordinary self-increment ID will become irregular. For example, 1 may become 2, 2 will become 5, each bit is independently used with an encryption template, and the set bit salt is added during the conversion, making the result of each conversion different. Even if the ID changes from 997 to 998 only changes one number, due to the difference in salt, the previously unchanged number will be replaced, thus obtaining a completely different value.

Advantages and application effects

The main advantage of using the ctfang/id-to-code library is that it can quickly and efficiently convert the self-increment ID into irregular code, thereby protecting the system's traffic information. At the same time, since the conversion process does not require complex calculations and has very high performance, it is very suitable for scenarios where IDs need to be processed frequently, such as order numbers, user IDs, etc. In addition, the code generated by this library is shorter in length, which is convenient for front-end use and transmission.

In practical applications, the ctfang/id-to-code library helps us successfully hide the system's business volume information, improve the system's security and privacy protection, while maintaining efficient processing speed, greatly improving user experience and system performance.
