Encode and decode an Adobe Dreamweaver password in *.ste file

问题

How is a password encoded or decoded in order to retrieve a password from an Adobe Dreamweaver *.ste file, or to dynamically create a *.ste file designed to be imported into Dreamweaver?

回答1:

This Javascript function can be used to encode the password:

function encodePassword(input)
{
    var top = 0;
    var output = '';

    for(var i = 0; i < input.length; i++){
        var currentChar = input.charCodeAt(i);
        if(currentChar < 0 || currentChar > 0xFFFF){return(false);}
        if(top != 0){
            if(0xDC00 <= currentChar && currentChar <= 0xDFFF){
                output += dec2hex(0x10000 + ((top - 0xD800) << 10) + (currentChar - 0xDC00) + i) + '';
                top = 0;
                continue;
                // Insert alert for below failure
            }else{return(false);}
        }
        if(0xD800 <= currentChar && currentChar <= 0xDBFF){top = currentChar;}
        else{output += dec2hex(currentChar + i) + '';}
    }

    return(output);
}

function dec2hex(input){return(input+0).toString(16).toUpperCase();}

And this function can be used to decode the password:

function decodePassword(input)
{
    var output = "";

    if(input.length == 0){return("");}

    for(var i = 0; i < input.length / 2; i++){
        var currentHex = parseInt(input.substr(i * 2, 2), 16);
            if(currentHex <= 0xFFFF){
                output += String.fromCharCode(currentHex - i);
            }else if(currentHex <= 0x10FFFF){
                currentHex -= 0x10000
                output += String.fromCharCode(0xD800 | (currentHex >> 10)) + String.fromCharCode(0xDC00 | (currentHex & 0x3FF) - i);
            }else{
                //Insert alert for below failure
                return(false);
        }
    }

    return(output);
}

You can also do this online without any code using this tool: http://blog.affirmix.com/2009/05/05/live-ste-dreamweaver-password-encoder-and-decoder/

To decode the Dreamweaver password you break the password into pairs of hexadecimal (0-9, A-F) digits then subtract from each hex digit based on it's position in the string, starting with 0, then convert back to ascii.

The encrypted password of 5470714865787F would be...

54-0 = 54 => T  
70-1 = 6F => o  
71-2 = 6F => o  
48-3 = 45 => E  
65-4 = 61 => a  
78-5 = 73 => s  
7F-6 = 79 => y

So 5470714865787F => 'TooEasy'

We have a working example of this on our website which allows you to decode your password. You can also copy/paste your entire .ste file and it will output the needed FTP details to connect, save some time...

Sorry to wake up an old thread but thought I'd post my solution. It's a single HTML5 page that can load and parse Dreamweaver STE files, decoding the password as part of that. I wanted something simple, offline/local (so details aren't transmitted when decoding) that I could to just load an STE file in to and it would give me all the FTP details:

Hope it's useful to someone!

Waking an old thread, but in addition to the accepted JavaScript answer, I just wanted to leave two PHP functions for anyone interested:

To encode a password:

function dwste_encode( $pw ){
    $output = '';
    $split = str_split( $pw );
    foreach( $split as $key => $value ){
        $char = ord( $value );
        $char = ( $char + $key );
        $char = dechex( $char );
        $output .= strtoupper( $char );
    }
    return $output;
}

To decode a password:

function dwste_decode( $pw ){
    $output = '';
    $split = str_split( $pw, 2 );
    foreach( $split as $key => $value ){
        $char = hexdec( $value );
        $char = ( $char - $key );
        $char = chr( $char );
        $output .= $char;
    }
    return $output;
}
