有没有办法从Chrome扩展程序访问证书信息

Question

我想从Google Chrome扩展程序中访问SSL证书信息.

我在这里查看了API:http://code.google.com/chrome/extensions/api_index.html,但没有看到任何可以完成工作的内容.

理想情况下,我想访问发行人,有效期,主题,序列号等...

这似乎可以在Mozilla/Firefox中实现:

2018答:webextensions(使用Chrome扩展API)可以在Firefox 62中执行此操作

您需要创建一个WebExtension,也称为浏览器扩展.

请参阅访问MDN上的安全信息

您还可以查看以下文档:

• getSecurityInfo
• 安全信息
• 证书信息.

你需要Firefox 62.

这是一个工作 background.js

var log = console.log.bind(console)

log(`\n\nTLS browser extension loaded`)

// https://developer.chrome.com/extensions/match_patterns
var ALL_SITES = { urls: ['<all_urls>'] }

// Mozilla doesn't use tlsInfo in extraInfoSpec 
var extraInfoSpec = ['blocking']; 

// https://developer.mozilla.org/en-US/Add-ons/WebExtensions/API/webRequest/onHeadersReceived
browser.webRequest.onHeadersReceived.addListener(async function(details){
    log(`\n\nGot a request for ${details.url} with ID ${details.requestId}`)

    // Yeah this is a String, even though the content is a Number
    var requestId = details.requestId

    var securityInfo = await browser.webRequest.getSecurityInfo(requestId, {
        certificateChain: true,
        rawDER: false
    });

    log(`securityInfo: ${JSON.stringify(securityInfo, null, 2)}`)

}, ALL_SITES, extraInfoSpec) 

log('Added listener')

manifest.json:

{
    "manifest_version": 2,
    "name": "Test extension",
    "version": "1.0",
    "description": "Test extension.",
    "icons": {
        "48": "icons/border-48.png"
    },
    "background": {
        "scripts": ["background.js"]
    },
    "permissions": [
        "webRequest",
        "webRequestBlocking",
        "<all_urls>"
    ]
}

一旦合并此代码,它也可以在Chromium中实现.

您可以使用 aNPAPI plugin 来做到这一点。
