Sangano reNational Institute of Standards and Technology (NIST) razivisa kuti hashing algorithm yadzikiswa, haina kuchengetedzeka, uye haina kukurudzirwa kushandiswa. Izvo zvakarongwa kubvisa kushandiswa kweSHA-1 kusvika Zvita 31, 2030 uye kuchinja zvachose kune yakachengeteka zvakanyanya SHA-2 uye SHA-3 algorithms.
Pakazosvika Zvita 31, 2030, zvese zvazvino NIST zvakatemwa uye mapuroteni haachashandisi SHA-1. Kupera kweiyo SHA-1 kutsanangurwa kucharatidzwa mune itsva federal standard FIPS 180-5. Pamusoro pezvo, shanduko dzichaitwa kune zvinoenderana nezvinodiwa, senge SP 800-131A, kubva panozobviswa kutaurwa kweSHA-1. Cryptographic modules inotsigira SHA-1 haizokwanisa kupasa bvunzo inotevera paNIST uye kuendesa kwavo kumasangano ehurumende yeUS hazvigoneke (chitupa chinopihwa kwemakore mashanu chete, mushure mezvo bvunzozve inodiwa).
SHA-1 yakagadziriswa muna 1995 uye yakabvumidzwa seyemubatanidzwa ruzivo rwekugadzirisa chiyero (FIPS 180-1), ichibvumira kushandiswa kweiyi algorithm mumasangano ehurumende yeUS. Muna 2005, iyo theoretical mukana wekurwiswa kweSHA-1 yakaratidzwa. Muna 2017, yekutanga kudhumhana kurwiswa ine prefix yakapihwa yakaratidzwa yeSHA-1, iyo inobvumira maviri akasiyana data seti kuti asarudze ekuwedzera, iyo inosungirirwa iyo inozokonzera kudhumhana uye kuumbwa kweiyo yakafanana inoguma hashi (semuenzaniso. , kune magwaro maviri aripo, unogona kuverenga maviri ekuwedzera, uye kana imwe yakanamirwa kugwaro rekutanga uye imwe kune yechipiri, inoguma SHA-1 hashes yemafaira aya ichave yakafanana).
Muna 2019, nzira yekuona kudhumhana yakavandudzwa zvakanyanya uye mutengo wekurwisa wakaderedzwa kusvika pamakumi ezviuru zvemadhora. Muna 2020, kurwiswa kwekushanda kwakaratidzwa kugadzira manyepo ePGP uye GnuPG siginecha yedhijitari. Kubva 2011, SHA-1 yakaregedzwa kushandiswa mumasiginecha edhijitari, uye muna 2017, mabhurawuza makuru ese akamira kutsigira zvitupa zvakasainwa vachishandisa SHA-1 hashing algorithm. Nekudaro, SHA-1 inoramba ichishandiswa kumacheki, uye kune anopfuura zviuru zviviri nemazana maviri akasimbiswa SHA-2200-enabled cryptographic modules nemaraibhurari muNIST dhatabhesi.
