Menene ƙimar hash

Ƙimar hash wata ƙima ce ta tsayi mai tsauri da ake ƙirƙira ta hanyar lissafi daga bayanai, inda shigarwa ɗaya koyaushe tana samar da ƙima ɗaya, kuma idan akwai bambanci na harafi ɗaya a shigarwa, sakamakon zai bambanta gaba ɗaya. Ba zai yiwu a dawo da asalin bayanai daga ƙimar ba.

Bambanci tsakanin MD5 da SHA-256

MD5：MD5 wani tsoho ne na aiki na hash wanda ke fitar da lamba ta hexadecimal mai lambobi 32, mai sauri amma ba a ba da shawarar amfani da shi don dalilan tsaro saboda an gano hanyoyin samar da karo.
SHA-256：SHA-256 wani aiki na hash na yanzu da aka yarda da shi wanda ke fitar da lamba ta hexadecimal mai lambobi 64, ana amfani da shi sosai don sa hannun lantarki da tabbatar da cikakkiyar fayil (don adana kalmar sirri, ana amfani da hanyoyi na musamman kamar bcrypt).

Menene HMAC

HMAC wani hash ne wanda ake ƙirƙira ta hanyar haɗa maɓalli na sirri, wanda ban da gano canjin bayanai, kuma yana ba da damar tabbatar da cewa 'ƙimar an ƙirƙira ta ne daga wanda ya san maɓalli', kuma ana amfani da shi sosai don sa hannu ga buƙatun API.
