I-US National Institute of Standards and Technology (NIST) imemezele ukuthi i-hashing algorithm isiphelelwe yisikhathi, ayiphephile, futhi ayinconyelwe ukusetshenziswa. Kuhlelelwe ukususa ukusetshenziswa kwe-SHA-1 ngo-December 31, 2030 futhi kushintshele ngokuphelele kuma-algorithms aphephe kakhudlwana e-SHA-2 ne-SHA-3.
Ngomhla ka-31 Disemba 2030, zonke izicaciso zamanje ze-NIST namaphrothokholi ngeke zisasebenzisa i-SHA-1. Ukuyeka umhlalaphansi kwencazelo ye-SHA-1 kuzobonakala ku-FIPS standard FIPS 180-5 entsha. Ngaphezu kwalokho, izinguquko zizokwenziwa ekucacisweni okuhlobene, okufana ne-SP 800-131A, okuzosuswa kuyo ukubhekisela ku-SHA-1. Amamojula we-Cryptographic asekela i-SHA-1 ngeke akwazi ukudlulisa ukuhlolwa okulandelayo kwe-NIST futhi ukulethwa kwawo ezikhungweni zikahulumeni wase-US ngeke kube yinto engenakwenzeka (isitifiketi sikhishwa iminyaka emihlanu kuphela, ngemva kwalokho ukuhlolwa kwesibili kuyadingeka).
I-SHA-1 yathuthukiswa ngo-1995 futhi yagunyazwa njengezinga lenhlangano yokucubungula ulwazi (i-FIPS 180-1), evumela ukusetshenziswa kwalesi simiso se-algorithm kuma-ejensi kahulumeni wase-US. Ngo-2005, kwafakazelwa ukuthi kungenzeka ithiyori yokuhlasela i-SHA-1. Ngo-2017, ukuhlasela kokuqala kokushayisana okungokoqobo okunesiqalo esinikeziwe kwaboniswa ku-SHA-1, okuvumela amasethi edatha amabili ahlukene ukukhetha okungeziwe, okunamathiselwe kwakho okuzoholela ekushayisaneni nokwakhiwa kwe-hashi engumphumela ofanayo (isibonelo, emibhalweni emibili ekhona kungenzeka ukubala izengezo ezimbili, futhi uma enye inamathiselwe kudokhumenti yokuqala, kanti enye kweyesibili, umphumela we-SHA-1 hashes kulawa mafayela uzofana).
Ngo-2019, indlela yokuthola ukushayisana yathuthukiswa kakhulu futhi izindleko zokuhlasela zehliswa zaba amashumi ezinkulungwane zamadola. Ngo-2020, ukuhlasela okusebenzayo kwaboniswa ukudala amasiginesha mbumbulu we-PGP ne-GnuPG. Kusukela ngo-2011, i-SHA-1 iye yahoxiswa ukuthi isetshenziswe kumasiginesha edijithali, futhi ngo-2017, zonke iziphequluli zewebhu ezinkulu zayeka ukusekela izitifiketi ezigunyazwe kusetshenziswa i-algorithm ye-SHA-1 hashing. Nokho, i-SHA-1 iyaqhubeka nokusetshenziselwa amasheke, futhi kunamamojula e-cryptographic aqinisekisiwe angaphezu kuka-2200 namalabhulali anosekelo lwe-SHA-1 kusizindalwazi se-NIST.
