Fedora 35-s on plaanis \u00fcleminek paroolide hashingu skeemi yescrypt kasutamisele. Muudatus pole veel FESCo (Fedora Engineering Steering Committee), mis vastutab Fedora jaotise tehnilise arenduse eest, arutelu alla tulnud. Kui muudatus heaks kiidetakse, hakatakse Fedora 35-s uute kasutajate paroolid failis \/etc\/shadow vaikimisi hashima yescryptiga. Vanade hashide tugi, mis on loodud varem kasutatud sha512crypt algoritmi alusel, j\u00e4\u00e4b alles ja on saadaval valikuna.
