在BASH中解密PHP openssl_seal - Decrypt PHP openssl_seal in BASH

我正在尝试解密一些通过PHP openssl_seal加密的数据。网上似乎没有任何涉及bash的例子（花了一段时间研究此事），所以我认为这篇文章也会对其他人有所帮助。

据我所知，我必须首先使用我的私钥解密用于实际数据的RC4加密的密钥。数据本身以及RC4密钥以base64格式存储。

数据：

Y3jrrTI96HVK7aMR/LrLnCGsqlQNvpQN8TTEoClak2GHk1MMV5/Ig6CD5EuojJaI
gey79XGjf8S9IqLsJ/MxOjODSFM48D+G0lbBW9GEOUFB027pfuHDhyMoTsxjEFBG
XIz5

环境：

JJXy5kX9RNSd90BgRSKUX1AGZhwbzetVHKAZTv1/HCBEPGqaGvoWdxaiA8UaJAAr
mS7Sh3pbMm1GN41BYi2r4m9VONknIqn3VB+cikA7ZRxmKOVhRuJTgdjWhrCMyxls
1osAsC8lIFkLo13Z1v8IZAXKGIdyO86WHXzfQku8HAE=

测试私钥（这个是加密的，非加密的添加在问题的最底部）：

所以我在做：

从base64解码（尝试在没有base64的情况下获取数据，结果仍然相同/使用base64确保编码等没有问题）：

base64—解码envkey>envun

用我的私钥解密envkey：

openssl rsoutl-demitter-inkey private.pem-in/tmp/envun-out/tmp/envdec

获得解密的二进制（？）密钥并使用它解密RC4:中的数据

openssl enc-d-rc4-in加密-输出解密-传递文件：envdec

然而，我得到的是：

坏幻数

有什么建议吗？

非加密私钥：

如何加密：

$pub_key_ids = [];
$sealed = '';
$pub_key_string = file_get_contents("/usr/local/ssl/public.pem");
$pub_key = openssl_get_publickey($pub_key_string);
if ($pub_key) {
    $pub_key_ids[] = $pub_key;
}
if (count($pub_key_ids)) {
    if (openssl_seal($params['deployment_settings'], $sealed, $ekeys, $pub_key_ids) !== false) {
        $data = base64_encode($sealed);
        $envkey = base64_encode($ekeys[0]);
    }
    foreach ($pub_key_ids as $pub_key_id) {
        openssl_free_key($pub_key_id);
    }
}

作为bash的问题代表，我们可以使用一些bashms：

一体化：

printf "'nResult: %s'n" $?

这可能会输出：

A combination of genetic and environmental factors play a role in the development of schizophrenia.

通过使用函数

这可能更有用：

#!/bin/bash
declare Data=./datas
declare Envkey=./envkey
declare PrivateKey=./privkey
b64Dec() { base64 -i --decode                   ; }

rsaDec() { openssl rsautl -decrypt -inkey $1 -in $2        ; }
rc4Dec() {
    openssl rc4 -d -iv 0 -K "$1"
    printf >&2 "'nResult: %s'n" $?
}
rc4Enc() {
    openssl rc4 -iv 0 -K "$1"
    printf >&2 "'nResult: %s'n" $?
}
declare Key="$(hxDump  < <(rsaDec $PrivateKey <(b64Dec <$Envkey)))"
b64Dec <$Data | rc4Dec $Key
rc4Enc $Key <<eoGeorgOrwellQuote | base64
In our age there is no such thing as 'keeping out of politics.' All issues
are political issues, and politics itself is a mass of lies, evasions,
folly, hatred and schizophrenia.

使用openssl本机命令，您可以执行以下操作：

base64 --decode envkey > envun
openssl rsautl -decrypt -inkey private.pem -in envun -out envdec
KEY=$(cat envdec |hexdump -v -e '/1 "%02X"')
openssl rc4 -d -a -in encrypted -iv 0 -K "$KEY"

您必须使用"-a"标志，因为您的内容是base64编码的。

您可以在命令行模式下使用php和"-q"来抑制标题。

  php -q decrypt.php data.txt envkey private.pem

解密内容.php

<?php
$pkeyid=openssl_get_privatekey(file_get_contents($argv[3]));
$content=base64_decode(file_get_contents($argv[1]));
$envkey=base64_decode(file_get_contents($argv[2]));
if (openssl_open($content, $data, $envkey, $pkeyid)) {
    echo "$data'n";
} else {
    echo openssl_error_string()."'n";
}
openssl_free_key($pkeyid);

这将比使用openssl本机命令容易得多。
