US National Institute of Standards and Technology (NIST) tau tshaj tawm tias hashing algorithm tsis siv, tsis muaj kev nyab xeeb, thiab tsis pom zoo siv. Nws tau npaj kom tshem tawm kev siv SHA-1 los ntawm lub Kaum Ob Hlis 31, 2030 thiab hloov mus rau qhov kev nyab xeeb dua SHA-2 thiab SHA-3 algorithms.
Thaum Lub Kaum Ob Hlis 31, 2030, tag nrho cov kev qhia tshwj xeeb thiab cov txheej txheem NIST tam sim no yuav tsis siv SHA-1 lawm. Cov nyiaj laus ntawm SHA-1 cov lus qhia yuav raug cuam tshuam hauv tsoomfwv tus qauv tshiab FIPS 180-5. Tsis tas li ntawd, cov kev hloov pauv yuav raug ua rau cov kev qhia tshwj xeeb, xws li SP 800-131A, los ntawm kev siv rau SHA-1 yuav raug tshem tawm. Cryptographic modules uas txhawb nqa SHA-1 yuav tsis tuaj yeem dhau qhov kev tshuaj xyuas tom ntej los ntawm NIST thiab lawv qhov kev xa mus rau tsoomfwv Meskas cov koomhaum yuav ua tsis tau (daim ntawv pov thawj tsuas yog muab rau tsib xyoos, tom qab ntawd yuav tsum muaj kev tshuaj xyuas zaum ob).
SHA-1 tau tsim nyob rau hauv 1995 thiab pom zoo raws li tsoom fwv teb chaws cov ntaub ntawv txheej txheem (FIPS 180-1), tso cai rau siv cov algorithm no nyob rau hauv US tsoom fwv cov koom haum. Hauv xyoo 2005, qhov kev xav tau ntawm kev tawm tsam SHA-1 tau ua pov thawj. Hauv xyoo 2017, thawj qhov kev sib tsoo thawj zaug nrog cov lus qhia ua ntej tau tshwm sim rau SHA-1, tso cai rau ob qhov sib txawv cov ntaub ntawv los xaiv ntxiv, qhov txuas uas yuav ua rau muaj kev sib tsoo thiab tsim cov txiaj ntsig zoo ib yam (piv txwv li, rau ob daim ntawv uas twb muaj lawm nws tuaj yeem suav ob qhov ntxiv, thiab yog tias ib qho txuas rau thawj daim ntawv, thiab lwm yam rau qhov thib ob, qhov tshwm sim SHA-1 hashes rau cov ntaub ntawv no yuav zoo ib yam).
Hauv 2019, txoj kev tshawb nrhiav kev sib tsoo tau txhim kho zoo thiab tus nqi ntawm kev tawm tsam tau txo qis rau ntau kaum txhiab nyiaj. Hauv xyoo 2020, kev tawm tsam ua haujlwm tau tshwm sim los tsim PGP thiab GnuPG cov kos npe cuav. Txij li xyoo 2011, SHA-1 tau raug txwv tsis pub siv rau hauv kev kos npe digital, thiab xyoo 2017, tag nrho cov web browsers loj tau tso tseg kev txhawb nqa daim ntawv pov thawj uas siv SHA-1 hashing algorithm. Txawm li cas los xij, SHA-1 tseem siv rau kev txheeb xyuas, thiab muaj ntau dua 2200 cov ntawv pov thawj cryptographic modules thiab cov tsev qiv ntawv nrog SHA-1 kev txhawb nqa hauv NIST database.
