Indlela States MD5-hashe: A Simple Indlela

Kumashumi eminyaka akutshanje, umba yobumfihlo kunye nokhuseleko ulwazi baba ngakumbi echaphazelekayo. Kungenxa yoko le nto iinzame rhoqo ukuze ikhowudi data usebenzisa ubuchule yakutshanje. Enye indlela enjalo ukusebenzisa i asa algorithm igama MD5. Indlela States MD5-hashe ngoku kwaye ziza kuqwalaselwa. Noko ke, ngokukodwa ithemba ukufumana ulwazi uyamxhaxha okugqitha okanye naluphi na olunye ulwazi oluyimfihlo kufuneka babale ngenxa ubunzima yenkqubo efana kunye ngokungekho mthethweni.

Yintoni MD5-hashe?

Ngokuqhelekileyo, a hashing ukuguqula ukuqonda nasiphi data umtya engenayo obude ethile, emelwe hexadecimal notation bit-128 isiseko, esebenzisa algorithm okhethekileyo.

Ngamanye amazwi, le nkqubo ayikwazi kubizwa ngokuba encryption. Kwaye ngoko thina sikwazi ukuthetha ukungafihli njani MD5-hashe, ekubeni kukho ezinye iindlela ngolwazi. Ukongeza, kule meko, inkqubo computing ekhethekileyo zonke ozama ukuwufunda negates.

Indlela States MD5-hashe: Imigaqo ngokubanzi

Ngelo engcono ukwenzeka, ungaya kuphela malunga ngokukhetha umxholo efunekayo ngeendlela ezintathu eziphambili:

• sebenzisa isichazi-magama;
• isicelo i "iitafile umnyama";
• Iuni indlela.

Ukuqala technology MDA5-hashing yaphuhliswa kwi Massachusetts Institute of Technology, ikhokelwa ngu uNjingalwazi Ronald L. Rivest. Ukususela ngoko lisetyenziswa njengenye yeendlela OpenPGP ukugcina amagama okugqitha kunye nezitshixo intanethi, yogesi, ngokujonga isidima yefayile, ukudala identifier web, khangela iifayile nempinda , njl Ke, njengoko kukholelwa ukuba ukungafihli MD5 iindlela algorithmic hashe-ngqo nzima kakhulu (kodwa hayi ayinakwenzeka), ngenxa yokuba nkqu utshintsho omnye wabalinganiswa kuboniso shestnadtsatrichnom obuquka utshintsho oluzenzekelayo bonke abanye. Ngoko ke, kukho indlela kuphela, ezibizwa ngokuba Iuni (uphazamiseko ngamandla ndisisilo). udityaniso japan kunjalo elula ifomu neloqobo ngokukhawuleza.

Ukusebenzisa imithombo online

Ukuba kukho unjalo imfuneko yokuba zokucazulula, kuba ukubala, ungenza axhamle iinkonzo ezininzi imithombo online, unika iinkonzo zabo. NgokoMthetho jikelele umgaqo osebenza kuxhomekeke kwinto yokuba umsebenzisi ongena umgca okhethekileyo kulandelelwano site, ngokuxhomekeka zokucazulula, uze iyazingenela inkqubo yokhetho.

Ukuba ulwazi enkhowudingi yokuqala yakho usebenzisa ulwimi PHP kuthetha, kwezinye iimeko, iinkonzo online unokusebenzisa indibaniselwano base_64 encode / base_64 ngokwezandi. Kuyo nayiphi na imeko, indlela ibandakanya kuphela ukhetho yeesimboli, amanani okanye oonobumba indibanisela enqwenelwa kuthelekiswa uvimba apho agcinwe iziphumo imizekelo iibhakhowudi.

Indlela States MD5 hashe-ngokwakho?

Abanye abasebenzisi bazama States asa ikhowudi yayo. Kodwa ke, njengoko kuvela, kube kakhulu nzima. Ukuze lula le nkqubo, ukusebenzisa ngcono eziluncedo ziwuphose egxile, phakathi ezimi ngaphandle ngokucacileyo ezi program zilandelayo:

• PasswordPro.
• UYohane nekhuba.
• UKayin & Abheli.
• "Shtirlits" et al.

Iinkqubo ezimbini zokuqala ziyilelwe ukubala imixube zilula sifake indibaniso ezisisiseko ezifana 1212121.

Eyesithathu kubonakala ukuba Ungaguqulelwa kwi khowudi lo MD5-hashe, kodwa oko ngokucotha kakhulu. Noko ke, inzuzo yalo kukuba has a ephelele itafile wenkunkuma, nkqu umsebenzisi uninitiated nale kunzima ukuqonda.

"Stirlitz" - isicelo umdla kakhulu, kodwa usebenzisa inani kakuhle algorithms computing, phakathi leyo ebaluleke kakhulu ezifana BtoA, uuencode, base64, xxencode kunye binhex.

Ukuba nokuba aphumileyo, ufuna ukusebenzisa eluncedo Iuni BarsWF, nto leyo ekhule zonke ezaziwayo kwaye kwiimeko ezininzi uyakwazi ukubonakalisa okufihliweyo MD5-hashe (password, ukuba ikhona, nazo bangeniswe kwifom efunekayo), asebenza kunye ezigidi computing hashi elinesibini . Kodwa, nkqu kunye nokusetyenziswa kwezi software kufuneka ithathele ingqalelo ixesha yaye, ngaphandle kokuba algorithm basic, MDA5-Coding inokwenziwa ngexesha elinye usebenzisa MD4 okanye IM.

Kodwa nangona konke oku, hashing inokufumaneka izikhewu ezininzi. Iingcali ezininzi zikholelwa ukuba ubude ikhowudi nkqu bit-128 iziseko lisezantsi kakhulu, ngoko ke uphuhliso software nokwandisa amandla azo lweenkqubo iprosesa mihla inkqubo khowudi yasiwa kumbhalo uba ixesha elide, nto leyo esisizathu sokuba nophuhliso kunye nokusetyenziswa kwemali ezinjalo sele kubonakala kakhulu inexpedient.

isiphelo

Kuhleli ukongeza ukuba ususe MD5-hashe akakwazi ukusebenzisa kuphela izixhobo ngasentla. Ukuba ezindala elungileyo kwi Internet, uyakwazi ukufumana ezi nkqubo kakhulu. Umbuzo: nokuba nenxaxheba kolu hlobo nto oyifunayo? Kubonakala ukuba umsebenzisi avareji nayiphi na inkqubo lwekhompyutha ulwazi kungenakwenzeka ukuba abe luncedo.
