[sunjester]

I wrote it for another post on the forum, i just don't remember where. but here it is in full. run it from the command line. this is for bcrypt passwords (the default password encryption for php's password_hash() and crypt() functions)

Code:

<?php
#!/usr/bin/php
//sunjester
$wordlist = "words.txt";
$enc = "encrypted.txt";

if(startup($wordlist,$enc))
{
        $fh = fopen($wordlist, "r");
        $enc_pws = loadEncryptedPws($enc);

        foreach($enc_pws as $epw)
        {
                echo "checking password: $epw";
                //start checking with the dictionary
                if($fh)
                {
                        ob_start();
                        while(($line = fgets($fh)) !== false)
                        {
                                echo ".";
                                ob_flush();

                                $pw = password_hash($line, PASSWORD_DEFAULT);
                                if(password_verify($line, $epw))
                                {
                                        printf("Found password: %s ", $line);
                                        printf("(%s)\n", $epw);
                                }
                        }
                        fclose($fh);
                }
        }
} else {
        die("startup failed");
}

function loadEncryptedPws($e)
{
        $fh = fopen($e, "r");
        $pws = [];

        while(($line = fgets($fh)) !== false)
        {
                array_push($pws, $line);
        }

        fclose($fh);
        return $pws;
}

function startup($w,$e)
{
        if(php_sapi_name() != "cli")
        {
                return false;
        }

        if(!file_exists($w) || !file_exists($e))
        {
                return false;
        }

        return true;
}
?>

words.txt is the wordlist, a word on each line of the file. (https://github.com/dwyl/english-words)
