IPurism imemezele izolo ukuthi ilindelwe kakhulu Ukhiye wokuphepha we-Librem Key USB uyatholakala ukuze uthengwe njengokhiye wokuqala nowokuphela kwe-OpenPGP wokunikeza i-Heads firmware (inkampani ekhethekile) ehlanganiswe ne-boot tamper-proof.
Ithuthukiswe ngokubambisana neNitrokey, inkampani eyaziwa ngokukhiqiza okhiye bokuphepha be-USB abane-software yamahhala evumela ukubhaliswa okuphephile nedatha esayiniwe kuma-laptops, IPurism's Librem Key inikezelwe kubasebenzisi beLebrem laptop, ivumela ukugcina okhiye abangama-4096-bit nokhiye be-ECC abangafika kuma-bits angama-512, kanye nokwenza izinkinobho ezintsha ngqo kusuka kudivayisi. ILibrem Key ihlangana nenqubo evikelekile yokuqalisa ama-laptops eLibrem 13 ne-15.
Ukubethela i-Diski neposi, ukufakazela ubuqiniso, kanye ne-boot yokuphazamisa ukhiye owodwa wokuphepha
Idizayinelwe ukuvumela abasebenzisi beLaptop beLibrem ukuthi babone ukuthi ngabe kukhona ophazamise isoftware yabo yekhompyutha lapho iqala, Ukhiye weLibrem usekelwa yi I-chip ye-TPM (Module Platform Module) enamakhanda inikwe amandla etholakala kumaLaptop amasha eLibrem 13 kanye ne-15. Ngokusho kwePurism, lapho kufakwa ukhiye wezokuphepha ukhanyisa okuluhlaza ukubonisa abasebenzisi ukuthi i-laptop ayiphazanyiswanga, ngakho-ke bangaqhubeka lapho begcine khona, uma ibenyeza i-Red It kusho ukuthi ilaptop iphazanyisiwe.
Ngokwengeziwe, ukhiye weLibrem uletha amakhono avamile okuphepha atholakala kumathokheni ejwayelekile okuphepha, njengamandla okusindisa okhiye be-GPG nokusayina kokubethela ukuze kusetshenziswe kumadivayisi amaningi, amandla okusindisa okhiye bokufakazela ubuqiniso be-GPG ngezikhathi ze-SSH, nokusekela. Ukusebenzisa i-One- Amaphasiwedi Esikhathi noma Ukuqinisekiswa Kwezinyathelo ezimbili ukufinyelela amawebhusayithi ahlukahlukene.
Njengoba iPurism iqhubeka nokwenza ngcono ukuphepha kwamaLaptops eLibrem futhi isebenza kanzima ukwethula iselula ebhekwe ngabomvu iLibrem 5 ngeLinux, inkampani inezinhlelo ezinkulu zeLibrem Key futhi, sezivele zicabanga ukukhulisa amakhono azo ukwesekwa ukuthola ukuphazamiseka ngesikhathi sokuthumela, phakathi kwezinye izinto eziningi.
