Kodi kumvetsa ndi MD5-hasi: Njira Zambiri

M'zaka zapitazi, nkhani ya chinsinsi ndi chitetezo cha mfundo akukhala zogwirizana kwambiri. N'chifukwa chake zoyesayesa zonse chitetezo deta ntchito ma aligorivimu atsopano. Njira ndiyo ntchito chete aligorivimu MD5 dzina. Kodi kumvetsa ndi MD5-chete tsopano ndi tidzakambirana. Komabe, makamaka chiyembekezo kupeza chidziwitso pa kuwakhadzula mapasiwedi kapena zina zomwe chinsinsi sayenera kuwerenga chifukwa cha vuto lotero ndondomeko ndi malamulo.

Kodi MD5-chete?

Nthawi zambiri hashing kusandutsa kumvetsa aliyense deta ukubwera chingwe cha kutalika ena, akuimira mu hexadecimal kalembedwe 128-bit maziko, ntchito aligorivimu wapadera.

M'mawu ena, mnjira sitinganene kuti kubisa. Ndipo kotero sitingathe kulankhula za mmene decrypt MD5-chete, chifukwa pali ntchito njira zina za kupereka mauthenga. Komanso, mu nkhani iyi, ndi wapadera kompyuta dongosolo kuti onse akufuna decrypt negates.

Kodi kumvetsa ndi MD5-hasi: mfundo

Chabwino, likhoza bwanji posankha zili analakalaka njira zitatu:

• ntchito mtanthauzira mawu;
• ntchito ya "matebulo utawaleza";
• Brutus njira.

Kuyambira luso MDA5-hashing anayamba kupanga pa Institute Massachusetts of Technology, anatsogoleredwa ndi Pulofesa Ronald L. Rivest. Popeza ndiye chimagwiritsidwa ntchito monga imodzi mwa njira kubisa kwa kasungidwe mapasiwedi ndi makiyi online, siginecha pakompyuta, poona filesystem kukhulupirika, kulenga identifiers ukonde, kufufuza owona chibwereza , etc. Ndipo, monga akukhulupirira kuti decrypt ndi MD5 hasi-mwachindunji algorithmic njira yovuta kwambiri (koma osati zosatheka), chifukwa ngakhale kusintha kwa mmodzi wa anthu a mu shestnadtsatrichnom chifaniziro kumatanthauza kusintha basi ena onse. Choncho, pali njira ankatchedwa Brutus (kusokonezedwa ndi mphamvu chakuthengo). chifukwa Komabe yosavuta kuphatikiza mu mawonekedwe original ngati nkotheka.

Ntchito chuma Intaneti

Ngati ndi choncho pali chosowa cha decoding, kwa starters, inu tingalandire ntchito zosiyanasiyana Intaneti chuma, kupereka mautumiki awo. Mu mau mfundo ya ntchito kwagona kuti wosuta akulowa mzere wapadera pamalowa akuyambira phunziro kwa decoding, kenako imayendetsa ndondomeko kusankha.

Ngati kabisidwe mfundo koyamba pogwiritsa ntchito chinenero Php kumatanthauza zina, ntchito Intaneti mwina ntchito osakaniza base_64 encode / base_64 decode. Mulimonsemo, njira amatenda kokha kusankha zizindikiro, manambala kapena zilembo kuphatikiza anakhumba poyerekezera ndi Nawonso achichepere limene zasungidwa zotsatira zitsanzo yosiyanasiyana.

Kodi kumvetsa ndi MD5 hasi-nokha?

Ena amene kuyesera kumvetsa kwa chete malamulo a yake. Koma, ngati likukhalira, kukhale kovuta kwambiri. Wosalira njirayi, azigwiritsa ntchito zofunikira pang'onong'ono cholinga, imene bwinobwino mapulogalamu zotsatirazi:

• PasswordPro.
• Yohane Ripper.
• Kaini & Abel.
• "Shtirlits" neri Al.

Ndondomeko awiri oyamba tinapangidwa kuwerengera ma losavuta ndi m'malo ma zikuluzikulu monga 1212121.

Wachitatu Zikuoneka kuti athe decrypt ndi MD5-chete, koma amachita zimenezi pang'onopang'ono. Komabe, ntchito yake ndi kuti ali wathunthu tebulo jenereta, ngakhale sazidziwa bwinobwino wosuta ndi izi Kwapafupi kumva.

"Stirlitz" - kugwiritsa ntchito ndi chidwi kwambiri, koma lidalembedwa ndi ochepa okha a kompyuta ma aligorivimu, Pakati zofunika kwambiri monga BtoA, uuencode, base64, xxencode ndi binhex.

Ngati ngakhale kuti wapita, muyenera kugwiritsa ntchito zofunikira Brutus BarsWF, ndilo yachangu onse odziwika milandu ndipo ambiri akhoza decrypt MD5-chete (achinsinsi, ngati aliyense, akhoza kubweretsa mawonekedwe anakhumba), ntchito ndi mabiliyoni a kompyuta ya chete wachiwiri . Komabe, ngakhale ntchito pulogalamu imeneyi ayeneranso kuganizira nthawi ndi kuti, kupatula aligorivimu zofunika, MDA5-wolemba pulogalamu angathe kuchitidwa imodzi ntchito MD4 kapena IM.

Koma ngakhale izi, hashing angapezeke mipata ambiri. Akatswiri ambiri amakhulupirira kuti malamulo kutalika ngakhale ndi maziko 128-bit ndi otsika kwambiri, choncho chitukuko cha pulogalamu ndi uzigwira zowerengera kachitidwe kamakono purosesa ndondomeko decryption amakhala nthawi yochepa wowononga, nchifukwa chake chitukuko patsogolo ndi ntchito ndalama kale zikuwoneka ndithu inexpedient.

Pomaliza

Mpaka kuwonjezera kuti decrypt MD5-chete silingakhoze kokha ntchito zida pamwamba. Ngati rummage zabwino Intaneti, mungapeze ndondomeko kwambiri. funso ili: kaya amachita mtundu umenewu chinthu mukufuna? Zikuoneka kuti pafupifupi wosuta a kompyuta nzeru ngati silingakhale zothandiza.
