Instituti Komb\u00ebtar i Standardeve dhe Teknologjive t\u00eb SHBA (NIST) e ka shpallur algoritmin e hash SHA-1 t\u00eb vjet\u00ebruar, t\u00eb pap\u00ebrshtatsh\u00ebm p\u00ebr k\u00ebrkesat e siguris\u00eb dhe t\u00eb pap\u00ebrshtatsh\u00ebm p\u00ebr p\u00ebrdorim.

SHA-1 u zhvillua n\u00eb vitin 1995 dhe u miratua si nj\u00eb standard federal p\u00ebr p\u00ebrpunimin e informacionit (FIPS 180-1), duke lejuar p\u00ebrdorimin e k\u00ebtij algoritmi n\u00eb institucionet shtet\u00ebrore t\u00eb SHBA. N\u00eb vitin 2005 u v\u00ebrtetua mund\u00ebsia teorike e nj\u00eb sulmi ndaj SHA-1. N\u00eb vitin 2017 u demonstruar sulmi i par\u00eb praktik me kolizion me prefiks t\u00eb caktuar p\u00ebr SHA-1, i cili lejon q\u00eb p\u00ebr dy grupe t\u00eb ndryshme t\u00eb t\u00eb dh\u00ebnave t\u00eb gjenden shtesa, t\u00eb cilat, kur bashkohen, do t\u00eb \u00e7ojn\u00eb n\u00eb formimin e nj\u00eb kolizioni dhe krijimin e t\u00eb nj\u00ebjtit hash rezultatues (p.sh., p\u00ebr dy dokumente ekzistuese, mund t\u00eb llogariten dy shtesa dhe, n\u00ebse nj\u00ebra i bashkohet dokumentit t\u00eb par\u00eb dhe tjetra dokumentit t\u00eb dyt\u00eb \u2014 hash rezultatues t\u00eb SHA-1 p\u00ebr k\u00ebto skedar\u00eb do t\u00eb jen\u00eb t\u00eb nj\u00ebjta). <\/p>\n

N\u00eb vitin 2020, u demonstruar nj\u00eb sulm funksional p\u00ebr krijimin e n\u00ebnshkrimeve digjitale fallco PGP dhe GnuPG. Q\u00eb nga viti 2011, SHA-1 nuk rekomandohet p\u00ebr p\u00ebrdorim n\u00eb n\u00ebnshkrimet digjitale, dhe n\u00eb vitin 2017, t\u00eb gjith\u00eb shfletuesit kryesor\u00eb ndaluan mb\u00ebshtetjen p\u00ebr certifikatat e verifikuara me algoritmin e hash SHA-1.
