<script language="php"> function passgen($len) { $pass = ""; if($len > 5 && $len < 17) { srand((double) microtime() * 1000000); for($i=0;$i<12;$i++) { $pass .= chr(rand(0,255)); } $pass = substr(base64_encode($pass), 0, $len); } return $pass; } </script> <!-- Function passgen (above) creates a random password suitable for any use. The generated passwords are pure junk - using mixed alpha, numeric and a few symbols. Usage: passgen(int password_length); Password length can be anything from 6 to 16 characters. Other length values result in an empty string being returned. Method: Quite simple. A string of 12 random 8 bit characters is built up in a loop. The resulting random 12 bytes of data are then UU-Encoded which provides a 16 character string of mixed case, numerics and a few symbols. This is then shortened to the length requested in the parameter passed to passgen to return a random password of the requires length. Example usage below (you can just chuck this on a server to see what it does). Strip out the function above to use it in your own code. --> <html> <head> <title>Password Generator</title> </head> <body bgcolor="#FFFFFF"> <p> <font face="Arial" size="4"> Password generator example </font> </p> <pre> <script language="php"> for($i=0;$i<8;$i++) { echo passgen(8)."<br>"; } </script> </pre> </body> </html> | |||||
