Me pēhea te ki te kīa te MD5-hae: A Tikanga Simple

I roto i te tekau tau tata nei, kei te hoko atu e hāngai ana te take o te matatapu me te haumaru o te mōhiohio. Ko te aha ki te ngana tamau whakamuna raraunga mā te whakamahi i te hātepe hou. Ko tētahi taua tikanga ko te ki te whakamahi i te ingoa MD5 hae hātepe. Me pēhea te ki te kīa te MD5-hae ko inaianei, a ka kia whakaaro. Heoi, rawa tumanako ki te whiwhi mōhiotanga ki runga ki hacking kupuhipa ranei e kore e tatau tetahi atu mōhiohio matatapu no o te fifi o te tukanga taua me te illegality.

He aha te mea te MD5-Hash?

Ko te tikanga, he hashing taui i matau tetahi string raraunga taumai o te tetahi te roa, māngai i roto i hautekaumāono momotuhi pūtake moka-128, mā te whakamahi i te hātepe motuhake.

I roto i te mau parau te tahi atu, e kore e taea e huaina tenei tukanga whakamunatanga. A kia kore e taea e tatou e te kōrero e pā ana ki te pehea, ki te wetemuna MD5-hae, mai reira e whakamahia atu tikanga o te whakaatu mōhiohio. I tua atu, i roto i tenei take, he pūnaha rorohiko motuhake e whakamātau katoa ki te wetemuna te roopu.

Me pēhea te ki te kīa te hash- MD5: te mau parau tumu whānui

I pai, e taea anake e haere i te reira e pā ana ki te kōwhiri i te ihirangi e hiahiatia ana i roto i te toru ara matua:

• te whakamahi i te papakupu;
• tono o te "tepu aniwaniwa";
• tikanga Brutus.

I whakawhanakehia Tīmata hangarau MDA5-hashing i te Institute Massachusetts o Technology, arahina e Ahorangi Ronald L. Rivest. Mai reira Kei te whānui whakamahia reira rite tetahi o nga tikanga whakamunatanga mō te rokiroki kupuhipa me taviri ipurangi, waitohu hiko, te taki i te tapatahi pūnaha, te hanga pūwehe tukutuku, rapu hoki ngā kōnae tārite , me ētahi atu Na, kia rite ki te whakapono ai ki te wetemuna te tikanga hae-hāngai MD5 algorithmic tino uaua (engari e kore e taea), no te mea tura'ii te ara he huringa o tetahi o nga pūāhua i roto i te shestnadtsatrichnom kanohi i te huringa aunoa o nga ētahi atu katoa. Ko te kupu, i reira te mea he tikanga anake, nuitia huaina Brutus (pokanoa ki kaha hopukanga). hua huinga Heoi ohie i roto i te puka taketake rite taea.

Mā te rauemi ipurangi

Ki te pera i reira ko te hiahia o te wetemuna, mo kamata, ka taea e te tango e koe painga o maha ratonga rauemi ipurangi, whakahere ratou ratonga. I roto i ngā whānui te parau tumu o te mahi takoto i roto i te meka e tomo te kaiwhakamahi te raina motuhake i runga i te raupapa pae, i raro ki te wetemuna, a ka whakahohetia te tukanga whiriwhiri.

Ki te tikanga o te mōhiohio whakawaehere tuatahi hua te whakamahi i te reo PHP, i roto i ētahi wā, kia whakamahi i ngā ratonga ipurangi te huinga o te base_64 whakawaehere / base_64 Wetewaehere. I roto i tetahi take, tā te tikanga te kōwhiringa anake o tohu, tau pukapuka i roto i te huinga e hiahiatia ana ranei i te rite ki te pātengi raraunga i roto i nei e rongoa nga hua o tauira ā.

Me pēhea te ki te kīa te hae-koe MD5?

Ētahi kaiwhakamahi tamata ki kīa te waehere hae o ona ake. Ko, rite huri i te reira i roto i, kia tino uaua te reira. Hei te faaohie i tēnei tukanga, kia pai ake te whakamahi o taputapu, matatau tonu arotahi, i roto i nei tu i roto i mārama te hōtaka e whai ake nei:

• PasswordPro.
• Hoani te Ripper.
• Kaina & Apera.
• "Stirlitz" et al.

Kua hangaia te hōtaka tuatahi e rua ki te tātai i te ngā māmā e whakakapi ngā taketake pērā i 1212121.

Ko te tuatoru te mea ki te taea ki te wetemuna te MD5-hae, engari e te reira na rawa āta. Heoi, tona painga ko e te mea he generator tepu oti, ara te kaiwhakamahi uninitiated ki tenei whakauaua matau.

"Stirlitz" - te tono, ko te rawa ngā, engari whakamahi reira he maha rawa iti o rorohiko hātepe, i roto i nei te nui tino e pērā i BtoA, Uuwhakawaehere, hōtuku Base64, xxencode me BINHEX.

Ki te ara haere te taua, e hiahia ana koe ki te whakamahi i te whaipainga Brutus BarsWF, e ko te tere o mohiotia katoa me i roto i te nuinga o te wā ka taea e wetemuna MD5-hae (kupuhipa, ki te tetahi, e taea hoki te kawea ki roto ki te puka e hiahiatia ana), whakahaere ki pirioni o rorohiko te hae i roto i te rua o . Heoi, me tango hoki noa ki te whakamahi o ēnei pūmanawa ki pūkete te wa me e, haunga te hātepe taketake, MDA5-Tapa taea te whakamana te wā kotahi te whakamahi i MD4 IM ranei.

Ko ahakoa tenei katoa, e taea te kitea hashing maha āputa. He maha ngā tohunga whakapono e te roa waehere noa ki bit-128 turanga he iti rawa, a reira te whanaketanga o te pūmanawa, me te whakapiki ake i kaha tātai o ngā pūnaha pūtukatuka hou riro tukanga wetemunatanga iti wa e kai ana, i te mea he aha kua titiro te whanaketanga anō me te whakamahi o taua moni rawa kaore.

mutunga

tonu te reira ki te tāpiri i taua ki te wetemuna MD5-hae kore e taea te whakamahi i anake te taputapu i runga ake. Ki te he rummage pai i roto i te Internet, e taea e kitea e koe i enei hōtaka rawa nui. Ko te pātai, ko te: ahakoa ki te whai wāhi i roto i tenei ahua o te mea e hiahia ana koe? Te āhua e te kaiwhakamahi toharite o tetahi pūnaha rorohiko taua matauranga he pea ki te whai hua.
