Ka weheweheʻana o MD5 a me kona History and Vulnerabilities
ʻO MD5 (i kapaʻiaʻo MD5 Message-Digest Algorithm ) he hana hash cryptographic nona ke kumu nui ke hōʻoiaʻaʻole i hoʻololiʻia kahi faila .
Ma mua o ka hōʻoiaʻana heʻeluaʻano hōkeo o nāʻikepili i ka hoʻohālikelikeʻana i nāʻike kuhi, MD5 e hana ai i kēia ma ka hanaʻana i kahi loiloi ma nā papaʻelua, a laila e hoʻohālike ana i nā checksums e hōʻoia iā lākou he like.
Aia i ka MD5 kekahi hapa, no lailaʻaʻole pono i nā noi hoʻopunipuni i mua, akā uaʻoluʻolu loa ia e hoʻohana ai no nā hōʻoia hōʻoia.
E hoʻohana ana i MD5 Checker a iʻole MD5 Generator
ʻO Microsoft Kōnae Checksum Integrity Verifier (FCIV) kahi calculator liʻiliʻi e hiki ke hoʻopuka i ka helu MD5 mai nā faila maoli aʻaʻoleʻo kahi kikokikona wale nō. Eʻike i pehea e hōʻoia ai i ka pilina Feliʻi i Windows me FCIV e aʻo ai pehea e hoʻohana ai i kēia papahana kauoha .
ʻO kahi maʻalahi kahi e loaʻa ai ka MD5 kuala o kahi leka, nā helu, a me nā hōʻailona me ka mea hana Mira Miralad MD5 Hash Generator. Nui nā mea'ē aʻe e like me MD5 Hash Generator, PasswordSGenerator, a me OnlineMD5.
Ke hoʻohanaʻia ka likeh algorithm, ua hanaʻia nā hualoaʻa hoʻokahi. ʻO kēia keʻano hiki iāʻoe ke hoʻohana i hoʻokahi helu MD5 no ka loaʻaʻana o ka helu MD5 o kekahi mea pono a hoʻohana i kekahi helu MD5 ponoʻole e loaʻa nā hua like. Hiki ke hana hou ia me nā mea hana a pau e hana ana i kahi kānalua e kauʻia ma ka hana hash MD5.
Mōʻaukala & amp; Nā wānana o MD5
Ua hana 'iaʻo MD5 e Ronald Rivest, akā, hoʻokahi wale nō o kāna mau huahelu algorithmʻekolu.
ʻO ka hana hana mua a ia i hanaʻiaʻo MD2 i 1989, i kūkuluʻia no nā computerʻewalu-bit. ʻOiai e hoʻohana nei MD2 i kēia manawa,ʻaʻole ia no nā noi e pono ai ka palekana, no ka mea, uaʻikeʻia heʻano pilikino i nā mea kū'ē.
Ua paniʻia MD2 i MD4 i ka makahiki 1990. Ua hanaʻia MD4 no nā mīkini 32-bit a uaʻoi aku ka wikiwiki o MD2, akā ua hōʻikeʻia nō hoʻi kona mau nāwaliwali a uaʻaneʻaneʻia e ka Internet Engineering Task Force .
Ua hoʻokuʻuʻia ka MD5 i ka makahiki 1992 a ua kūkuluʻia no nā mīkini 32-bit. ʻAʻole wikiwiki ka MD5 e like me MD4, akā ua manaʻoʻia heʻoi aku ka maikaʻi ma mua o ka hana mua o MDx.
ʻOiai uaʻoi aku ka malu o MD5 ma mua o MD2 a me MD4, ua hoʻohālikelikeʻia kekahi hana hash cryptographic, e like me SHA-1 , i mea'ē aʻe, no ka mea, ua hōʻikeʻiaʻo MD5 i nā hewa o ka palekana.
Keʻike neiʻo Carnegie Mellon University Institute Engineering Institute i kēia mea e pili ana i MD5: "Nā mea hoʻomohala pūnaewele, nā Mana Hoʻohanohano, nā mea o ka pūnaewele, a me nā mea hoʻohana eʻae i ka hoʻohanaʻana i ka MD5 algorithm ma nāʻano a pau. hoʻohana hou. "
I ka makahiki 2008, ua hoʻokumuʻia ka MD6 i ka National Institute of Standards and Technology e like me ka mea'ē aʻe i SHA-3. Hiki iāʻoe ke heluhelu hou e pili ana i kēia noi maʻaneʻi .
ʻIke hou aku ma ka MD5 Hash
ʻO ka haʻalulu MD5 he 128-bits i ka lōʻihi a ke hōʻike mauʻia nei i ko lākou helu hexadecimal 32 he nui. Heʻoiaʻiʻo kēia no ka nui a me ka liʻiliʻi paha o ka waihona a iʻole ka kikokikona.
ʻO kahi o kēiaʻano hex he 120x8A25E5D487BF68B5F7096440019 , aʻo ka unuhi'ōlelo maʻalahi he "He hōʻailona kēia.". Hoʻoponopono i nā hua'ōlelo'ē aʻe e heluhelu i "He hōʻailona kēia e hōʻike ai peheaʻole ka lōʻihi o ka kikokikona." unuhi i kahiʻanoʻokoʻa loa akā me ka helu hoʻokahi o nā huapalapala: 6c16fcac44da359e1c3d81f19181735b .
ʻO kaʻoiaʻiʻo,ʻo kahi kaula me nā hua'ōlelo zero he waiwai hex o d41d8cd98f00b204e9800998ecf8427e , a me ka hoʻohanaʻana i hoʻokahi manawa ke kumu waiwai 5058f1af8388633f609cadb75a75dc9d .
Ua kūkuluʻia nā wili MD5 iʻole e hiki ke hoʻololiʻia,ʻo ia hoʻi,ʻaʻole hiki iāʻoe ke nānā i ka makaikai aʻike i kaʻikepili i hoʻokomoʻia. Me ka mea i'ōleloʻia, ua nui nā MDry "decrypters" i hoʻolahaʻia e hiki ai ke hoʻoholo i kahi waiwai MD5, akāʻo ka mea e hana neiʻo ia ka hanaʻana i ka loiloi no ka nui o nā waiwai a laila e nānāʻoe i kāu loli ma ko lākou waihonaʻikepili. eʻike inā loaʻa iā lākou kahi pāʻani e hōʻike iāʻoe i kaʻikepili mua.
ʻO MD5Decrypt a me MD5 Decrypterʻelua mau mea hana pūnaewele kūikawā hiki ke hana i kēia akā hana wale lākou no nā hua'ōlelo a me nā hua'ōlelo wale nō.
E nānā i ka mea he Checksum? no nā hiʻohiʻona o ka helu MD5 a me kekahi mau ala alaʻole e hoʻonui i ka waiwai MD5 mai nā waihona.
