Ua haʻi ka National Institute of Standards and Technology (NIST) i ka hashing algorithm i hoʻopau ʻia, palekana, a ʻaʻole i ʻōlelo ʻia no ka hoʻohana. Hoʻolālā ʻia e kāpae i ka hoʻohana ʻana iā SHA-1 a hiki i Dekemaba 31, 2030 a hoʻololi loa i nā algorithm SHA-2 a me SHA-3 paʻa.
Ma ka lā 31 o Kekemapa, 2030, ʻaʻole e hoʻohana hou nā kikoʻī NIST a me nā kaʻina hana i ka SHA-1. E hōʻike ʻia ka hopena o ka kikoʻī SHA-1 i ke kūlana federal hou FIPS 180-5. Eia kekahi, e hana ʻia nā hoʻololi i nā kikoʻī pili, e like me SP 800-131A, kahi e wehe ʻia ai ka haʻi ʻana o SHA-1. ʻAʻole hiki i nā modula Cryptographic e kākoʻo ana iā SHA-1 ke hele i ka hoʻāʻo aʻe ma NIST a ʻo kā lākou hāʻawi ʻana i nā keʻena aupuni US e lilo i mea hiki ʻole (e hāʻawi ʻia ka palapala hōʻoia no ʻelima mau makahiki wale nō, a laila koi ʻia kahi hoʻāʻo hou).
Ua hoʻomohala ʻia ʻo SHA-1 i ka makahiki 1995 a ua ʻae ʻia ma ke ʻano he maʻamau hoʻoponopono ʻike federal (FIPS 180-1), e ʻae ana i ka hoʻohana ʻana i kēia algorithm i nā keʻena aupuni o US. I ka makahiki 2005, ua hōʻike ʻia ka manaʻo o ka hoʻouka ʻana iā SHA-1. I ka makahiki 2017, ua hōʻike ʻia ka hoʻouka kaua ʻana mua me kahi prefix i hāʻawi ʻia no SHA-1, e hiki ai i ʻelua mau pūʻulu ʻikepili ke koho i nā mea hoʻohui, ʻo ka hoʻopili ʻana e alakaʻi i kahi hui ʻana a me ka hoʻokumu ʻana i ka hash hopena like (no ka laʻana. , no nā palapala ʻelua, hiki iā ʻoe ke helu i ʻelua mau mea hoʻohui, a inā pili kekahi i ka palapala mua a ʻo kekahi i ka lua, e like ana ka hopena SHA-1 hashes no kēia mau faila).
I ka makahiki 2019, ua hoʻomaikaʻi maikaʻi ʻia ke ʻano o ka ʻike ʻana i ka collision a ua hōʻemi ʻia ke kumukūʻai o ka hoʻouka kaua ʻana i mau ʻumi kaukani kālā. I ka makahiki 2020, ua hōʻike ʻia kahi hana hoʻouka kaua e hana i nā pūlima kikohoʻe PGP a me GnuPG. Mai ka makahiki 2011, ua hoʻopau ʻia ʻo SHA-1 no ka hoʻohana ʻana i nā pūlima kikohoʻe, a i ka makahiki 2017, ua pau nā polokalamu kele pūnaewele nui i ke kākoʻo ʻana i nā palapala hōʻoia i kau inoa ʻia me ka SHA-1 hashing algorithm. Eia nō naʻe, hoʻohana mau ʻia ʻo SHA-1 no nā checksums, a aia ma luna o 2200 i hōʻoia ʻia SHA-1-enabled cryptographic modules a me nā hale waihona puke ma ka waihona NIST.
