1,548,393 | 1,548,394 | RFC 2246 PRF function in PHP | <p>I've been looking all over for an implementation of the PRF function from RFC 2246. I've found three. One <a href="http://stackoverflow.com/questions/13324785/openssl-prf-function">here</a>, one from the openSSL library, and one from wpa_supplicant. They all return different results. So my first question is: is there sample PRF input and sample PRF output somewhere?</p>
<p>That function is part of connecting to a .NET web service (protected with WS-Security) from PHP.</p>
<p>What I've found so far is this. My client sends a request for a token first with a username/password and a nonce -- that's an RST. The server, in its RSTR, responds with another nonce and a security token. The next request from my client should come with a signature whose key is derived from the two nonces and a "master secret". That derived key is computed according to RFC 2246. And that's why I need a reliable implementation of it.</p>
<p>Even if I have a reliable implementation of it, what would constitute the parameters to that function in the context of WS-Security? The PRF function should take three parameters, i.e.:</p>
<p><strong>secret, label, seed.</strong></p>
<p>I've read <a href="http://www.codeproject.com/Articles/16427/Digging-into-SecureConversation-Part-I" rel="nofollow">here</a>, that the label Microsoft uses is "WS-SecureConversationWS-SecureConversation", but that article was written in 2006... Now, what would be the secret? Is it the original password? The security token? A combination of those? Finally, what would be the seed? I have two nonce's -- do I concatenate them, OR them, XOR them?</p>
<p>I'm seriously stuck. Any help greatly appreciated.</p>

1,095,012 | 1,095,013 | PHP specifying a fixed include source for scripts in different directories | <p>I am currently doing unit testing, and use folders to organize my test cases. All cases pertaining to managing of user accounts, for example, go under \tests\accounts. Over time, there are more test cases, and I begin to seperate the cases by types, such as \tests\accounts\create, \tests\account\update and etc.</p>
<p>However, one annoying problem is I have to specify the path to a set of common includes. I have to use includes like this:</p>
<pre><code>include_once ("../../../../autoload.php");
include_once ("../../../../init.php");
</code></pre>
<p>A test case in tests\accounts\ would require change to the include (one less directory level down). Is there anyway to have them somehow locating my two common includes? I understand I could set include paths within my PHP's configurations, or use server environment variables, but I would like to avoid such solutions as they make the application less portable and coupled with another layer which the programmer can't control (some web-host doesn't allow configuration of PHP's configuration settings, for example)</p>

</blockquote>
<p>but now I need to pass a third argument property like this:</p>
<blockquote>
<p>g_settings.iconUrl.docIcon</p>

<blockquote>
<p>if (extensions == 'doc'||extensions == 'docx'||extensions == 'xlsx'||extensions == 'xls)</p>

<p>and then I do:</p>

<p>and I need to use:</p>
<blockquote>
<p>g_settings.iconUrl.extension</p>
</blockquote>
<p>when I use <code>console.log(extensions)</code> it's value is as expected (for example <code>docIcon</code>) but when I try to use it as a property it doesn't work. If I use console.log on:</p>
<blockquote>
<p>console.log(g_settings.iconUrl+ '.' +extensions)</p>
</blockquote>
<p>the output is <code>[object Object].docIcon</code> so I think I have to convert somehow <code>extensions</code> to object too.
I'm not sure that this will solve the problem but that's what I have for now.</p>

Now i wanna add a textbox to limit how many rows at a time i will display. To test this, i wrote two button methods, one will set some rows to be visible = false, and the second button method will set the same rows back to visible = true.</p>
<pre><code>protected void limit_btn_Click(object sender, EventArgs e)
{
for (int i = 0; i < traceTables.Length; i++)
for (int j = 2; j < traceTables[i].Rows.Count; j++)
traceTables[i].Rows[j].Visible = false;
Session["Tables"] = traceTables;
table_C();
}//end limit_btn_Click()
protected void obo_btn_Click(object sender, EventArgs e)
{
for (int i = 0; i < traceTables.Length; i++)
for (int j = 2; j < traceTables[i].Rows.Count; j++)
traceTables[i].Rows[j].Visible = true;
Session["Tables"] = traceTables;
table_C();
}//end obo_btn_Click()
protected void table_C()
{
String changeTo = log_locations.SelectedValue;
for (int i = 0; i < sshLoc.Length; i++)
{
if (sshLoc[i].CompareTo(changeTo) == 0)
{
table_panel.ContentTemplateContainer.Controls.Remove(traceTables[currentTable]);
System.Diagnostics.Debug.WriteLine("Removing " + sshLoc[currentTable]);
table_panel.ContentTemplateContainer.Controls.Add(traceTables[i]);
System.Diagnostics.Debug.WriteLine("Adding " + sshLoc[i]);
currentTable = i;
Session["CurrentTable"] = currentTable;
break;
}//end if
}//end for
}//end table_C()
</code></pre>
<p>table_C() basically removes and adds the table from the panel - i use it when i want to switch between tables from a dropdown list (which works) and in this case it simply removes and adds the same table from the panel content container.</p>
<p>The problem is that setting the rows to be not visible works fine. Setting the rows back to visible never does, and i'm not sure why</p>

<p>Till date i was ignoring the php notices, thinking that we will disable it when website is live. Now a scenario has occurred where in clients have enabled logging of the notices also to the log and because of this the log size was growing enormously. I was always thinking that production environment will come with notices logging disabled. So we had to sit and remove each of these notices. So wanted to know will these notices cause any harm to website. Or should we take it as developers buggy code ? </p>

303,798 | 303,799 | Getting derived class objects out of a vector<Parent*> | <p>I know that you can store a bunch of Parent* objects in a vector. However, if the functions you need to call on the objects cannot be defined in the parent class (they depend on a template parameter of the subclass) then how are you supposed to retrieve the objects from the container?</p>
<p>In this example:</p>
<pre><code>#include <iostream>
class ImageBase{};
template <typename TPixel>
class Image : public ImageBase
{
public:
TPixel GetPixel() const {TPixel a; return a;}
};
template<typename TImage>
void Output(const TImage* image)
{
std::cout << image->GetPixel();
}
int main(int, char *[])
{
// Works correctly
{
Image<float>* image = new Image<float>;
image->GetPixel();
Output(image);
}
{
ImageBase* image = new Image<float>;
Output(image);
}
return 0;
}
</code></pre>
<p>The Output(image); where 'image' is a ImageBase* fails (of course) because GetPixel is not defined in ImageBase. I know you can dynamic_cast<> to a bunch of types to figure out if the subclass matches any of them, but this list could very quickly get very long. The long list would be fine if it could reside in one place, but how would you make a function to do this? The function would take an ImageBase*, but what would it return?</p>
<pre><code>returnType? GetSubclass(ImageBase* input)
{
if(dynamic_cast<Image<float>*>(input))
{
return Image<float>*;
}
else if(dynamic_cast<Image<int>*>(input))
{
return Image<int>*;
}
}
</code></pre>
<p>It seems reasonable to me to want to be able to call some template functions on subclasses that only vary in signature by their template parameter (as setup in this example), does it not?</p>
<p>In my real case, both Image and ImageBase are part of a library, so I cannot change them.</p>
