Kalkuleta na lambar hash SHA-512

SHA-512 (Tsarin Tsarin Hash Mai Tsaro 512-bit) aiki ne na hash mai ɓoyewa wanda ke ɗaukar shigarwa (ko saƙo) kuma yana samar da fitarwa mai girman 512-bit (64-bytes), wanda aka fi wakilta a matsayin lambar hexadecimal mai haruffa 128. Yana cikin dangin SHA-2 na ayyukan hash, wanda NSA ta tsara kuma galibi ana amfani da shi don aikace-aikace inda kuke buƙatar tsaro mai mahimmanci, kamar bayanai masu mahimmanci, adana bayanai na dogon lokaci, ɓoyewa na matakin soja, da kuma tabbatar da nan gaba daga barazanar da ke tasowa, kamar ƙididdigar kwantum.

Cikakken bayyanawa: Ban rubuta takamaiman aiwatar da aikin hash da aka yi amfani da shi akan wannan shafin ba. Daidaitaccen aiki ne wanda aka haɗa tare da yaren shirye-shiryen PHP. Na yi mahaɗin yanar gizo ne kawai don sanya shi a fili a nan don dacewa.

Game da Tsarin Hash na SHA-512

Ban ƙware sosai a fannin lissafi ba kuma ban taɓa ɗaukar kaina a matsayin masanin lissafi ba, don haka zan yi ƙoƙarin bayyana wannan aikin hash ta hanyar da sauran abokan aikina waɗanda ba masu lissafi ba za su iya fahimta. Idan kana son nau'in lissafi mai kyau a kimiyya, ina da tabbacin za ka iya samun hakan a wasu gidajen yanar gizo da yawa ;-)

Koma dai mene ne, bari mu yi tunanin cewa aikin hash wani injin hadawa ne mai fasaha sosai wanda aka tsara don ƙirƙirar wani nau'in smoothie na musamman daga duk wani sinadari da kuka saka a ciki. Wannan yana ɗaukar matakai uku:

Mataki na 1: Sanya Sinadaran (Shigarwa)

• Ka yi tunanin abin da za ka saka a matsayin duk wani abu da kake son haɗawa: ayaba, strawberries, yanka pizza, ko ma littafi gaba ɗaya. Ba kome abin da ka saka ba - babba ko ƙarami, mai sauƙi ko mai rikitarwa.

Mataki na 2: Tsarin Haɗawa (Aikin Hash)

• Kana danna maɓallin, sai injin blender ya yi tauri - yana yankawa, yana haɗawa, yana juyawa da sauri. Yana da girke-girke na musamman a ciki wanda babu wanda zai iya canzawa.
• Wannan girke-girke ya haɗa da ƙa'idodi masu ban mamaki kamar: "Juya hagu, juya dama, juya juye ƙasa, girgiza, sara ta hanyoyi masu ban mamaki." Duk wannan yana faruwa a bayan fage.

Mataki na 3: Kuna Samun Smoothie (Sakamako):

• Ko da kuwa irin sinadaran da ka yi amfani da su, injin blender ɗin koyaushe yana ba ka kofi ɗaya na smoothie (wannan shine matsakaicin girman bit 512 a SHA-512).
• Smoothie ɗin yana da ɗanɗano da launi na musamman dangane da sinadaran da kuka saka. Ko da kun canza ƙaramin abu ɗaya kawai - kamar ƙara ƙwayar sukari ɗaya - smoothie ɗin zai bambanta sosai.

Ni da kaina ina ɗaukar aikin hash na SHA-256 mai alaƙa da shi amintacce don dalilai na, amma idan kuna son wani abu ƙari, SHA-512 na iya zama hanya mafi kyau. Hakanan kuna iya bin hanyar tsakiya ku duba SHA-384: Link ;-)

Saboda yadda aka tsara shi, SHA-512 a zahiri yana aiki da sauri fiye da SHA-256 akan kwamfutocin bit 64, wanda ya haɗa da yawancin kwamfutocin tafi-da-gidanka da kwamfutocin tebur a lokacin rubutawa, amma ƙila ba ya haɗa da ƙananan tsarin da aka haɗa. Rashin kyau shine adana lambobin hash na SHA-512 yana buƙatar ninka lambobin hash na SHA-256 na ajiya sau biyu.

Kamar yadda ya faru, wasu mutane masu wayo sun fito da hanyar da za su sami mafi kyawun duka biyun, wato aikin hash na SHA-512/256: Link
