I have an install script. This script opens a website and allows you to enter values ​​as well as upload a certificate for HTTPS.

But the result doesn't look like the input file. Here is my code that parses a multipart body

var parseForm = function (data) {
    var reg = /-----------------------------.{12}(\r\n|\r|\n)Content-Disposition: form-data; name="/
    var sections = data.split(reg)
    var result = {}
    for (sec in sections) {
        var values = sections[sec].split(/\b"(\r\n|\r|\n)(\r\n|\r|\n)/)
        if (/certificate"; filename/.test(values[0])) {
            var key = values[0].replace(/"; filename=".*/i, '')
            var value = values[3].replace(/Content-Type: application\/x-pkcs12(\r\n|\n|\r)+/i, '').replace(/-----------------------------.{12}--(\r\n|\r|\n)/, '')
            result[key] = value
        } else if (values[3]) {
            var key = values[0]
            var value = values[3].replace(/(\r\n|\r|\n)/, '')
            result[key] = value
        }
    }
    return result
}

      

        
        
        
      

    

And this is what I use to save the file:

fs.writeFile(path.join(__dirname, 'server.p12'), parameter[p], function (err) {
    console.error(err)
    console.error('please copy the file to "' + __dirname + '" and name it server.p12')
})

      

        
        
        
      

    

Any idea why it is outputting data incorrectly? Or better yet, how can I fix this? :)

EDIT

Maybe the problem is that the file is not loaded proberly. Is it possible?

EDIT 2

Buffer

was just a remnant of a Notepad ++ test to validate binary data :)

EDIT 3

Here is the original certificate:

The certificates are encoded as bas64. I hope this helps. This is something encoded when I do base64 encoding and write it directly to the file it works. But I need to break it manually. All code is here
