There is no such thing as a MD5 Cracker. This is because of the way Md5 is encrypted, you can't possibly crack/decrypt it.

I was looking for that, and found out there's no software that can decrypt it unless you bruteforce.

Default Re: md5 Cracker

I've made an md5 cracker which uses brute force long back but never tried to see whether it works or not. It is in php and needs to be accessed via a browser(or php-CLI). The code for it is:

Code:
<?php function cString($inpTab) { $output = ""; foreach($inpTab as $value) { $output .= $value; } return $output; } ?> <?php $encmd5 = ''; //Please insert the md5 value here set_time_limit(0); $alpharay = array(); $alpharay = array('', 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z'); $out = array(); $m = 0; $string = array(); for($i=0; $i<=sizeOf($alpharay); $i++) { $out[0] = $alpharay[$i]; for($i2=0; $i2<=sizeOf($alpharay); $i2++) { $out[1] = $alpharay[$i2]; for($i3=0; $i3<=sizeOf($alpharay); $i3++) { $out[2] = $alpharay[$i3]; for($i4=0; $i4<=sizeOf($alpharay); $i4++) { $out[3] = $alpharay[$i4]; for($i5=0; $i5<=sizeOf($alpharay); $i5++) { $out[4] = $alpharay[$i5]; for($i6=0; $i6<=sizeOf($alpharay); $i6++) { $out[5] = $alpharay[$i6]; for($i7=0; $i7<=sizeOf($alpharay); $i7++) { $out[6] = $alpharay[$i7]; for($i8=0; $i8<=sizeOf($alpharay); $i8++) { $out[7] = $alpharay[$i8]; for($i9=0; $i9<=sizeOf($alpharay); $i9++) { $out[8] = $alpharay[$i9]; for($i0=0; $i0<=sizeOf($alpharay); $i0++) { $out[9] = $alpharay[$i0]; if(md5(cString($out)) == $encmd5) { finalize(1); } } } } } } } } } } } finalize(0); function finalize($xe) { if($xe == 1) { printf("Password has been cracked. The password is: <font color=\"#FF0000\">".cString($out)."</font>"); } else { printf("Sorry. Password couldn't be cracked"); } $end = time(); printf("Some statistics: "); printf("\n"); printf("Total time taken: "); $tdiff = $end - $start; printf($tdiff); printf(" seconds"); printf("\n"); printf("Thank for using phpBB password cracker"); die(); } ?>

You need to define a variable called $encmd5 in the beginning of the script. That variable is the md5() encrypted value. Check this script for the variable.

NOTE: It works for upto 10 characters of un-encrypted strings only and includes only the alphabets from a-z(lower case). To add more characters, add them to the $alpharay array().

NOTE: This is an untested script. It may or may not work or may stop other things from working ... He he.. use it at ur own risk.

Completely incorrect.

Rohan here has made one, and I do know somebody that has made an MD5 -AND- SHA1 cracker... he's starting a database of ... what did he tell me... 20 million cracked passwords.

Also try www.md5decoder.com

The problem with the md5() decryptrion is, with smaller string unique strings have unique md5 hashes but if you go to see, md5 is a 32-charactered hexadecimal string. So acknowledging that every string has a unique md5 hash, there are only 32^17 in this world i.e 38685626227668133590597632 strings in the world, which just does not seem possible. Hence while encrypting, there are infinite strings giving a common md5 hash, but while decrypting, it is supposed to return only one...

Hi there,

I would find it very upsetting if someone has made a stable crack for MD5 as it was proved impossible for a long time. Although, anything can be cracked, and there is always someone who can do it, people said the Titanic was unsinkable, first day out, it sank .

Although, MD5 is 32 characters long, therefore there is billions of combinations, so unless someone knew the logic of MD5 it would be impossible.

I will try that apparent MD5 crack above later, and if it works I take my hat off to the kid and suggest he Copyrights it, as it must be worth millions.

Although it isn't long until things get cracked.

It has been done, although not cracked... what is done is a database with entries for the word and hash, so a simple "SELECT word FROM table WHERE hash='the md5 hash'" would find any words that would have that hash. other tools are there such as John the Ripper that crack the sums by brute force, although they are limited by their dictionaries and amount of time you want to spend on it.

MD5 CAN be cracked, But CAN NOT be decrypted.
This is due to it not being an encryption, It's a hash. A hash is a one way calculation and encyption is part of a two way proocess, Encryption by it's very nature can be decrypted, a hash can not be dehashed.

look up cain and able.
