可逆（整数）ID 混淆器

创建类似于 imgur、pastebin、youtube 等使用的散列

默认密钥空间是标准的 base62 密钥空间。

安装

要将此包作为本地、按项目依赖项添加到您的项目中，只需将 moccalotto/idhash 作为依赖项添加到您的项目 composer.json 文件中，如下所示：

{
    "require": {
        "moccalotto/idhash": "~0.9"
    }
}

或者，简单地调用 composer require moccalotto/idhash

<?php

use Moccalotto\IdHash\IntHasher;
use Moccalotto\IdHash\StringKey;
use Moccalotto\IdHash\RandomKeyFactory;

require 'vendor/autoload.php';

// you can generate a randomized base62 key by running bin/random_key
$keyspace = '8w2JUNlFLxfuCXbjkOmBizsWHG9Ep5n4Pd70yZg63vAerQVTMIRhS1DKqocaYt';

// Create a key shuffler
// This is roughly the same as $key = str_shuffle($keyspace),
// but it guarantees that the output keyspace is different from the input keyspace
// It also ensures that we squash duplicate characters
$key_generator = new RandomKeyFactory($keyspace);

// generate a random key
$key = $key_generator->key();

// initialize a new IntHasher
$IntHasher = new IntHasher($key);

// generate new input value
$input_int = mt_rand();

// encode the integer into a hash
$hash_str = $IntHasher->intToHash($input_int);

// decode the hash into an integer
$output_int = $IntHasher->hashToInt($hash_str);

// print the process values to screen
printf('The generated key:  %s%s', $key->keyString(), PHP_EOL);
printf('Number to encode:   %d%s', $input_int, PHP_EOL);
printf('The encoded hash:   %s%s', $hash_str, PHP_EOL);
printf('Decoded number:     %s%s', $output_int, PHP_EOL);
printf('Success:            %s%s', $input_int === $output_int ? 'Yes' : 'NO!', PHP_EOL);

die($input_int !== $output_int);
