Ọdịiche dị n'etiti SHA-1, SHA-2, SHA-256 hash algorithms
Ka anyị bido site n’ịkọwa nleghara okwu algorithm.
Hash algọridim bụ ọrụ mgbakọ na mwepụ nke na-eme ka data ahụ bụrụ nke edobere, dịka ọmụmaatụ, ọ bụrụ na anyị were ahịrịokwu ọ bụla "Ola nwere pusi" wee mee ya site na algorithm CRC32 pụrụ iche anyị ga-enweta mbiri "b165e001". Enwere ọtụtụ algọridim na ha niile nwere ebumnuche ụfọdụ, ụfọdụ na-emeziwanye maka ụdị data, ndị ọzọ bụ maka nchekwa.
Maka anyị, ihe kachasị mkpa bụ algorithms SHA.
SHA - na-anọchi anya Hashing Hashing algorithm - eji maka nchekwa nchekwa. Ihe kachasị mkpa nke algorithm a bụ na hash enweghị ike ịgbanwe agbanwe na ihe pụrụ iche. Enweghi ike - data mbụ ga-adị mma ma amaghị. Ọpụrụiche - mpempe data abụọ dị iche iche enweghị ike ịmepụta otu igodo ahụ.
mbinye aka dijitalụ nwere mmetụta nke ukwuu - mgbanwe ọ bụla na akwụkwọ ahụ ga-agbanwe mbinye aka. Ọ bụrụ na anyị were ahịrịokwu ahụ ekwuru n'elu bụ "OLA MA KOTA" wee dee ya na mkpụrụedemede ukwu, anyị ga-enweta mbiri nke dị iche kpamkpam "baa875a6". Mbiri ọzọ pụtara na mbinye aka adịkwaghị irè.
SHA-1 NA SHA-2 bụ usoro abụọ nke algọridim. Ha dị iche na usoro owuwu na ogologo. SHA-2 bụ usoro kawanye mma nke SHA-1.
SHA-1 bụ 160 ibe n'ibe ogologo
SHA-2 pụtara n'ọtụtụ ogologo, ọtụtụ mgbe na 256 ibe n'ibe
Ihu hash buru ibu na-enye nchekwa ka ukwuu. Enwere ike igosipụta ọnụọgụ nke pụrụ iche dị ka ọnụọgụ, dịka ọmụmaatụ maka SHA-256 enwere 2 256 ekwe omume n'ịgwa. 2 256 ọnụ ọgụgụ a buru ibu karịrị ọnụọgụ ájá n'ụwa.
Ọ bụrụ na akwụkwọ onye ọrụ dabere na SHA-1 (ma ọ dị mma, n'ihi na e nyere ya tupu July 1), mbinye aka nke emere (mgbe July 1) kwenyere na asambodo a kwesịrị ịnwe ndebiri nke ọdịnaya ejiri aka gbakọọ na SHA-2 algorithm (ọ bụghị SHA-1). Yabụ ngwa na sistemụ IT ga - eme ọ bụghị naanị asambodo ọhụrụ, mana imirikiti niile na --emepụta mbinye aka na akàrà mgbe ị na - eji hash dịka SHA-2
Mmemme anyị wụnyelarị kwelarị taa ịrụ ọrụ nke ịkwanye ma na-enyocha ihe ndekọ elektrọnik jiri ọrụ SHA-2 hash.
