Question

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?

Answer 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);
}
