PHP中的双向加密 [英] Two-way encryption in PHP

问题描述

我的应用程序（显然）使用唯一的ID来区分记录。这个UID在URL中传递（例如 ./ examplepage.php？UID = $ example_int ）等等。

My application (obviously) uses a unique ID to distinguish records. This UID is passed in URLs (e.g. ./examplepage.php?UID=$example_int), among other things.

虽然我显然有服务器端验证，以确保客户端不访问其他客户端的数据，是否有双向加密方法，我可以在PHP中使用只传递加密的UID（例如 ./ examplepage.php？EUID = $ encrypted_int ），以进一步减少任何人认为嘿，如果我增加这个整数会怎么样的机会？

While I obviously have server-side validation in place to make sure clients don't access other clients' data, is there a two-way encryption method I can use in PHP to only pass encrypted UIDs (e.g. ./examplepage.php?EUID=$encrypted_int), to further reduce the chance of anyone thinking "hey, what happens if I increment this integer?"

TIA。

推荐答案

在ID旁边放置一个哈希，以确保其安全性，或者用额外的ID填充ID数据，甚至将ID转换为十六进制，这一切都会运行得很好，我想。

Placing a hash next to the ID to ensure it's security, or padding the ID with extra data, or even converting the ID to hex would all work fairly well I think.
