发送加密文件(zip或txt)-通过PHP-在Windows PC上可打开 [英] Send encrypted file (zip or txt) - via PHP - openable on Windows PC

问题描述

我需要通过电子邮件向用户发送一些最少的数据(但必须将其加密).

I have a need to send some minimal data via email to users (but it must be encrypted).

他们将需要对附件进行DL处理并使用某种易于使用的软件(PC/MAC)对其进行解密...这里有什么想法吗?

They would need to DL the attachment and decrypt it with some kind of easy to use software (PC / MAC)... any ideas here?

我的第一个想法是制作一个加密的zip文件，使它们可以使用7zip或winzip打开...但是我发现，使用典型的PHP/Linux应用程序是不可能的.

My first thought is to make an encrypted zip file that they can open with 7zip or winzip... but I have found that it can't happen with a typical PHP/Linux app.

推荐答案

您可以使用 mcrypt和河豚来加密邮件.您可以找到许多针对Blowfish的加密/解密程序，例如... http://www.di-mgt.com.au/mysecret.html

You can use mcrypt and Blowfish to encrypt message. You can find many encrypt/decrypt programs for Blowfish eg... http://www.di-mgt.com.au/mysecret.html

<?php

    $key = 'too many secrets?';
    $text = 'If you are paranoid, we know who you are and what you want. Stay online so we can trace you.';

    $crypt_text = mcrypt_encrypt(MCRYPT_BLOWFISH, $key, $text, MCRYPT_MODE_ECB);

    var_dump($crypt_text);

    $plain_text = mcrypt_decrypt(MCRYPT_BLOWFISH, $key, $crypt_text, MCRYPT_MODE_ECB);

    var_dump($plain_text);

?>

测试:

string(96) "dà¨gþJ\V$3Äö,'  [y€&"¼‚\•òÏ=$ÅdG|ÀœÀbáÌɽûÝÉ·'þØ?I½}8óTé5<-‹ôÞ¶Ÿ°ÅMcCê®JxØ@RIú£Ç‹™xÞ"
string(96) "If you are paranoid, we know who you are and what you want. Stay online so we can trace you.����"

我链接的程序需要这样的输入文件(您可以通过电子邮件轻松地将其制成).

The program I've linked needs input file like this (you can easily make it like that in email).
