rampart Posted October 31, 2010 Report Share Posted October 31, 2010 Nu stiu daca e ceva nou, dar tot postez.Pentru oricine are o placa video de la nVidia cu tehnologia CUDA, parolele md5 au devenit mai usor de spart prin bruteforce, asta daca nu te ajuta diferitele site-uri.Cerinte: - Linux Backtrack 4, Ubuntu ..., Windows XP(SP2 sau SP3), Vista, Sevenun procesor modern @1.5Ghz cu cel putin 512MB RAM, recomandat: procesor dual-core(sau quad) cu DDR2/DDR3. - o placa video CUDA-Enabled, gForce 8800GT pana la Tesla, Quadro si procesoarele astea noi FermiDownload Link: http://bvernoux.free.fr/md5/uploadFile?id=3Full Description: MD5 Crack GPU (The fastest LGPL GPU MD5 password cracker)Nu l-am testat inca, fiindca folosesc masini virtuale peste masini virtuale si placa grafica nu e recunoscuta bine, intru ASAP in windows si testez.

rampart Posted October 31, 2010 Author Report Share Posted October 31, 2010 Arunca un ochi SHA1/MD5/MD4 bruteforcer for ATI and nVidia GPUsEu stiu ca placile ATI nu au procesoarele pentru asa ceva(semantica, scuze expresia), desi fac acelasi lucru, dar cum sunt facute placile nVidia cu tehnologia CUDA, pe care s-a construit frameworkul de programare cu SDK-ul aferent, permite mai multa flexibilitate end-userului (in cazul de fata un programator). Daca ar fi asa ceva si pt ATI probabil ar aparea solutii viabile pe diferite teme cum sunt si pentru CUDA, encodare video, randare 3D, chestii similare Cell/BE processing etc etc Quote Link to comment Share on other sites More sharing options...
pyth0n3 Posted October 31, 2010 Report Share Posted October 31, 2010 (edited) ATI -> a intrat cam tîrziu cu func?iunile de calcul GPU dar folose?te ca framework OpenCL care e un standard Open care ofer? ?i posibilitatea de a folosi instruc?iunile SSE3 din GPUOpenCL poate fi folosit si cu NVIDIA , func?ioneaz? cu multe procesoare de tipul AMD, INTEL ,VIA,CELL etc Disponibilitate pt sisteme Linux, Windows,Mac Recent si Nvidia a adoptat acest standard SDK -> ATI Stream SDK v2.2 with OpenCL? 1.1 Support | AMD Developer CentralUnele teste efectuate demonstreaz? ca noile produse hardware de la ATI reu?esc sa fac? calcule mai rapide decît NvidiaProblema e ca aceste puteri nu au fost suportate de c?tre software-ul folositAu avut probleme si driver-urile Catalyst pana la versiune 9.12 deci merita sa folosi?i o versiune recenta Stream 1.4 era plin de BUG , asa ca au creat Stream 2.0 care a schimbat lucrurile pu?in Edited October 31, 2010 by pyth0n3 Quote Link to comment Share on other sites More sharing options...
rampart Posted October 31, 2010 Author Report Share Posted October 31, 2010 Si am inteles, stiam de OpenCL, dar traiam cu impresia ca este folosit doar pentru platformele de jocuri/graphics, nu si in alte aplicatii de calcul.E bine de stiut.

rampart Posted October 31, 2010 Author Report Share Posted October 31, 2010 (edited) OpenCL (Open Computing Language) NOT OpenGL (Open Graphics Language)Nu am confundat OpenCL cu OpenGL, stiam de OpenCL as it is, doar ca am citit despre el in contextul de aplicatii de tip mobile, de acolo am ramas cu impresia asta.LE: mai explicit, aplicatii de tip mobile, adica niste jocuri nextgen pe mobile, construite pe OpenCL, desi se poate sa gresesc.Era vorba de un articol aferent astuia: http://www.engadget.com/2010/08/12/carmack-blows-minds-with-id-softwares-rage-running-on-iphone-a/care nu il mai gasesc (how convenient for me ).

rampart Posted October 31, 2010 Author Report Share Posted October 31, 2010 Din cate vad eu.. lipseste ceva, sau na, poate asta e standardul,la criteriile de caractere dupa care sa faca brute force-ul sunt astea:-c <charset number>(default 2), 0=[0-9], 1=[a-z], 2=[a-z0-9], 3=[A-Z], 4=[A-Z0-9], 5=[A-Za-z], 6=[A-Za-z0-9], 7=All PrintablesC:\>Nu ar trebui sa fie si o sectiune cu special caracters: !@#~$_. si care mai sunt, sa ai ceva de genul a-z plus special caracters. ca asa.. daca dau all printables, ma/ne ia dracu..

rampart Posted November 1, 2010 Author Report Share Posted November 1, 2010 Totul se rezuma la cat de bine faci tu setarile si la cate milioane de combinatii pe secunda incearca, nu? fara GUI inseamna mai mult resurse pentru procesare ... o sa incerc sa fac asta din BT4, mi-a recunoscut placa dar sa vad daca o recunoaste ca si CUDA Enabled. Iar daca din BT4 tot ~238mil/sec imi face... eu zic ca e tot una, nu? sau e vreun aspect pe care l-am omis cu desavarsire din treaba asta?Off-Topic: ma gandeam sa fac un post pe tema, dar te intreb asa, Python3, si eu sunt roman convins sa zic asa, adica vorbim romaneste, scriem romaneste, in ciuda influentelor englezesti/americane ale oricarui geek de asta care e prezent aici pe forum, myself included (see, I did it again! ), ar fi dragut sa scriem cu diacritice si fara prescurtarile ASL/PLS, dar mi se pare al dracu de greu treaba asta, obisnuinta, e o curva! Am un dictionar care l-am integrat in sistem, si tot am incercat programe macar in Word/Office shit sa imi substituie si sa puna automat diacritice( mobile style, deci Swype, e Dumnezeu!) dar nu reusesc nici cum. How do you do it?! Multa perseverenta in a te obisnui sa tastezi si diacriticele?, sau folosesti ceva, altceva. Lumineaza-ma! Ceau! Quote Link to comment Share on other sites More sharing options...
