[RST] Hash Cracker

Recommended Posts

Trebuie sa aveti minim 50 de posturi pentru a face un 'request'.

RST hash cracker machine:

CPU: Intel core 2 duo 3.2 GHZ 8 MB l2

GPU: MSI Radeon HD6950 Twin Frozr III Power Edition OC 1GB DDR5 256-bit

Ram: 16 GB

OS: BackTrack 5 rc3

App: hashcat.net/oclhashcat-plus/

System ul de mai sus va fi tinut up non stop doar pentru acest job.

Pentru ca sa pot sa procesez requestul vostru va trebui sa raspundeti in urmatorul format:

Hash: b467979095aa4670bfa1eeb74a2fa17a

Tip Hash: md5

Informati aditionale1: limba: germana

Informati aditionale2: min/max caractere= 7/15

Informati aditionale3: caractere speciale = da

Bafta ;)

Bravo! Ca idei in plus as putea spune:

1. Un server HTTP, prin care utilizatorul sa-si poata selecta optiunile, care interactioneaza cu o procesare din background, fie threaduite (requesturile procesate simultan => pierdere din viteza), fie queued (first come, first served).

2. Sa faci si bani din asta

Tip Hash: md5

Informati aditionale1: limba: engleza

Informati aditionale2: min/max caractere= ??

Informati aditionale3: caractere speciale = ??

EDIT: Hash spart in 30Secunde pe configuratia respectiva, mersi mult.

La mine pe CPU era estimat la 11 ore :))

Salveaza hash + rezultat intr-o baza de date daca nu faci deja asta.

Deja fac asta, oricum se pare ca imi trebuie hdd de cel putin 4tb.

Momentan am doar 1tb.

M-am pus pe instalat backtrack 5r3, ubuntu ma bate la greu :))

O sa editez topicul cand totul este up.

LE: @mrjasdf Cum sa fie md5 simplu cand are salt ?

$1$o2qRSPae$DlEMlGIztqcMWZtMQbhw..


$1$o2qRSPae$ => salt
DlEMlGIztqcMWZtMQbhw.. => parola.

Cred ca parola este: 112233 ; Sa facem un test:


<?php

$parola = '112233';
$salt = '$1$o2qRSPae$';
echo 'Crypt hash: ' . crypt($parola, $salt) . "\n"

?>


hp ~ # php tex.php
Crypt hash: $1$o2qRSPae$DlEMlGIztqcMWZtMQbhw..
hp ~ #
