]]> With this online tool, you can easily escape and unescape strings (among other powerful things, explained below)…

If you want to bookmark it, you may prefer this shorter address: http://www.neoegm.com/software/intelligent-escaper-unescaper/. [Press the right mouse button and select the option offered by your browser to add it to your bookmarks/favorites.]


As you can see, there are several features… I’ll explain them one by one…

Escape

Calls the escape Javascript function, which encodes the special characters (with some exceptions).

Example:

Hello, this is a test
Hello%2C%20this%20is%20a%20test

Escape (Forced)

Encodes every character, no matter whether it is special or not. Ideal to make the strings not easily readable.

Example:

Hello, this is a test
%48%65%6C%6C%6F%2C%20%74%68%69%73%20%69%73%20%61%20%74%65%73%74

Unescape

Calls the unescape Javascript function, which decodes every encoded character. (The ones with the form %XX or %uXXXX).

Example 1:

Hello%2C%20this%20is%20a%20test
Hello, this is a test

Example 2:

%48%65%6C%6C%6F%2C%20%74%68%69%73%20%69%73%20%61%20%74%65%73%74
Hello, this is a test

Escape URL

Encodes the special characters, but respecting the URL syntax. It’s not the same as the “encodeURI” option, since this latter one calls the encodeURI Javascript function, which does not encode the following characters: 

; , / ? : @ & = + $ - _ . ! ~ * ' ( ) #

While this one just does not encode them where corresponding. Parameters, anchors and Unicode characters are supported…

Example:

http://www.example.com:84/This is my file named niño: the named place.doc
http://www.example.com:84/This%20is%20my%20file%20named%20ni%F1o%3A%20the%20named%20place.doc

Escape URL (Forced)

Similar to “Escape URL”, but forcing the normal character encoding as much as possible (without including the host). Ideal to make URLs hard to read at first glance.

Example:

http://www.example.com:84/This is my file named niño: the named place.doc
http://www.example.com:84/%54%68%69%73%20%69%73%20%6D%79%20%66%69%6C%65%20%6E%61%6D%65%64%20%6E%69%F1%6F%3A%20%74%68%65%20%6E%61%6D%65%64%20%70%6C%61%63%65%2E%64%6F%63

Escape URL (Forced + Host)

Similar to “Escape URL”, but forcing the normal character encoding as much as possible (host included). Ideal to make URLs hard to read at first glance.

Note: this syntax is not supported in some browsers.

Supported browsers: Internet Explorer, Google Chrome.
Unsupported browsers: Firefox, Lynx.

In the case of Firefox, the string gets decoded correctly (if the URL is valid), but it doesn’t open, you have to open it again with the decoded address (selecting it and pressing Enter). If the host doesn’t contain any dot, “www.” y “.com” al added automatically.

If you have support information for any other browser, please tell me and I’ll add it.

Ejemplo:

http://www.example.com:84/This is my file named niño: the named place.doc
http://%77%77%77.%65%78%61%6D%70%6C%65.%63%6F%6D:84/%54%68%69%73%20%69%73%20%6D%79%20%66%69%6C%65%20%6E%61%6D%65%64%20%6E%69%F1%6F%3A%20%74%68%65%20%6E%61%6D%65%64%20%70%6C%61%63%65%2E%64%6F%63

Intelligent Escape

This function is an intelligent version of “Escape”. It encodes the corresponding characters, but without re-encoding the already encoded data.

Example:

Partially%22%20encoded%20string. And I added this part.
Partially%22%20encoded%20string.%20And%20I%20added%20this%20part.

If we just pressed “Escape”, we would have received:

Partially%2522%2520encoded%2520string.%20And%20I%20added%20this%20part.

Intelligent Unescape

Calls the unescape Javascript function repeatedly until there’s nothing remaining to be decoded. Useful when a string was encoded several times.

Example:

%25%34%38%25%36%35%25%36%43%25%36%43%25%36%46
Hello

If we just pressed “Unescape”, we would have received:

%48%65%6C%6C%6F

Parse URL Parameters

It breaks a URL into its corresponding parameters. The anchor is left without unescaping in the end.

Example:

http://www.example.com:81/path/path/hello.php?a=3&b=Good%20Morning&c=El%20Ni%F1o#test-anchor
http://www.example.com:81/path/path/hello.php

a=3
b=Good Morning
c=El Niño

#test-anchor

Make URL with Parameters

Reconstructs a URL based in the specified URL + parameters + anchor.

Example:

http://www.example.com:81/path/path/hello.php

a=3
b=Good Morning
c=El Niño

#test-anchor

http://www.example.com:81/path/path/hello.php?a=3&b=Good%20Morning&c=El%20Ni%F1o#test-anchor

Escape +

It encodes the + characters. They are not escaped by the other functions, with the exception of “Escape (Forced)”.

Escape #

It encodes the # characters. They are not escaped by the other functions, with the exception of “Escape (Forced)”.

Escape: <char>

It encodes the characters specified in the input box.

encodeURI

Calls the encodeURI Javascript function.

decodeURI

Calls the decodeURI Javascript function.

encodeURIComponent

Calls the encodeURIComponent Javascript function.

decodeURIComponent

Calls the decodeURIComponent Javascript function.

]]> As a new sequel to the Excel random password generator and the Random password generator, I’ve made a PHP random password generator service…

You can call it this way (if you hover the parameter values, you’ll get an explanation):

http://www.neoegm.com/services/random_password.php?length=8&upper=1&lower=1&numbers=1

So, for example, to generate a 10 characters numeric password you could access:

http://www.neoegm.com/services/random_password.php?length=10&upper=0&lower=0


That’s all, now the code for the ones who want to use it on their own sites (read below for license)…



GNU GPL v3The code is licensed under the GNU GPL v3…



Anyway, here is the code so you can watch it without having to download the PHP file:

function make_seed()	//Function make_seed from http://www.php.net/manual/en/function.srand.php
{
  list($usec, $sec) = explode(' ', microtime());
  return (float) $sec + ((float) $usec * 100000);
}

function RandomPassword($length, $upper = true, $numbers = true, $lower = true)
{
	if (!$upper &amp;&amp; !$lower &amp;&amp; !$numbers)
		return &quot;&quot;;

	$ret = &quot;&quot;;

	$chars = 26 * 2 + 10;	//26 (a-z) + 26 (A-Z) + 10 (0-9)
		//a-z = 97-122
		//A-Z = 65-90
		//0-9 = 48-57
		
	srand(make_seed());		//Seed with microseconds
							//if you don't need this, you can just use srand(time());

	for ($i = 1; $i &lt;= $length; $i++)
	{
		$repeat = false;

		$num = floor(rand(0, $chars-1));

		if ($num &lt; 26)
			if ($lower)
				$ret .= chr($num + 97);
			else
				$repeat = true;
		else if ($num &lt; 52)
			if ($upper)
				$ret .= chr($num - 26 + 65);
			else
				$repeat = true;
		else if ($num &lt; 62)
			if ($numbers)
				$ret .= chr($num - 52 + 48);
			else
				$repeat = true;

		if ($repeat)
			$i--;
	}

	return $ret;
}

And this is the code needed to make it a web service:

$length = isset($_REQUEST['length'])?$_REQUEST['length']:8;
$upper = isset($_REQUEST['upper'])?$_REQUEST['upper']:true;
$numbers = isset($_REQUEST['numbers'])?$_REQUEST['numbers']:true;
$lower = isset($_REQUEST['lower'])?$_REQUEST['lower']:true;

if ($length &lt; 1 || $length &gt; 128)
	$length = 8;

if (!($upper == false || $upper == 0))
	$upper = true;

if (!($numbers == false || $numbers == 0))
	$numbers = true;
	
if (!($lower == false || $lower == 0))
	$lower = true;

echo RandomPassword($length, $upper, $numbers, $lower);
