Try using <?php instead of <?

A good resource on regex is: http://www.regular-expressions.info/

Without doing too much work, you can embed games from existing websites.

Eg: miniclip.com

No problem, and thanks. :D

It is daunting to try and understand a large piece of code. That is why I posted the process, in a few simple lines.

Great script by the way.. :D

And yes, the regex can be improved, that is...

This it the embed code for that particular page:

<object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/NMAYr709-9Y&hl=en_US&fs=1&"></param><param...

To ensure an image is reloaded, send a unique URL.

eg:

<img src="image.php?random-number123" />

Where random_number123 can be generated by:

<?php

If you're getting the error:

Cannot modify header information - headers already sent by

Add ob_start() to the beginning of the script.

To explain how this is done:

First you make a http request to the page you want to parse.

eg:

$url = 'http://example.com/';
$content = file_get_contents($url);

Then you parse the HTML....

You can send SMS for free to most carriers by sending an email to their Email to SMS gateway.

A list of carriers is here:

...

Since the links are external domains, you'll need to have PHP act as a proxy.

You'll have PHP make a HTTP request to the site, and fetch the meta, title and images by parsing the returned HTML. ...

CRC32 should NOT be used at all. Not as the last hash output, or before you hash it again with a secure hash. Just not at all.

@OmniX The length of the salt does matter. The salt should be random, yes, but it should also be long enough to make the precomputation attack infeasible.

Are you using ob_start() before any PHP code?

eg:

<?php
ob_start();
include_once('session.php');
include_once('config.php');
// .. etc...
?>

The whole array or string does not need to be kept in memory, in order to generate the hash. The hash can be generated by writing the input in 1 byte at a time.

Example:

// sha1_stream.php...

After thinking about this again, I realized I made an assumption that is very incorrect. I assumed hash functions require the whole input in order to produce the hash.

But it appears the hash is...

Looks great. I modified the class I wrote a bit after looking at your code.

Just a few suggestions:

You could optimize the string concatenation.

$buffer .= hash($algo, $input . $salt);
...

Thought I'd write an example:

note: for PHP4 just remove the "public static" in front of each function declaration.

The class:

/**
* Generate cryptographic Hashes for passwords
*
*...

You can save the number of iterations used on the hash. That way you can start with just a few, say 1000, then add more if needed. Computation speed is always increasing so to keep the password safe...

There really is no reason to use 2 way encryption on passwords. Retrieving the password is not the concern, gaining access to their account is. So if the user forgets their password, send them a...

There is a finite set of possible hashes, since hashes are of a finite length.

You're right, you don't need to store all the hashes, such as what rainbow tables do ...

If you are after optimized queries, another way is to save the day, month, and year as individual INT columns.

That way you can use the indexes on the INT columns, just as you would a timestamp,...

Please post your question in a new thread instead of resurrection a thread that is years old.

Why not just save the whole hash generated by whirlpool? Using md5 effectively reduces the size of the hash, making it easier to guess (find collisions).

Sorry for resurrecting an old thread. But it was referenced recently and I thought I'd add to it.

crc32b should not be used with passwords as it is an insecure hash function. ...

Your web host support should be helpful there.

From the shell, do:

echo $PATH

To see each folder that is searched for commands.

You can then just search each folder like:
