Ucoceko lubhengeze izolo ukuba lulindelwe kakhulu Isitshixo sokhuselo lwe-USB esingundoqo siyafumaneka Ukuthengwa njengesitshixo sokuqala kunye nesisemthethweni se-OpenPGP sokubonelela ngeeNtloko ze-firmware (inkampani ekhethekileyo) edityaniswe ne-boot-proof proof.
Iphuhliswe ngokudibeneyo neNitrokey, inkampani eyaziwa ngokuvelisa izitshixo zokhuselo ze-USB ngesoftware yasimahla eyenza ukubhaliswa okukhuselekileyo kunye nedatha esayiniweyo kwiilaptops, Isitshixo sePurism sikaLibrem sinikezelwe kubasebenzisi beelaptop zaseLibrem, Ukuvumela ukugcina amaqhosha angama-4096-bit kunye nezitshixo ze-ECC ukuya kuthi ga kwi-512 bits, kunye nokuvelisa amaqhosha amatsha ngqo kwisixhobo. Isitshixo seLibrem sidityaniswa nenkqubo yokukhuseleka yeLibrem 13 kunye neelaptops ezili-15.
Idiski kunye nokubethela nge-imeyile, ukungqinisisa, kunye nokufaka ubungqina bokudibanisa ubungqina kwisitshixo esinye sokhuseleko
Yenzelwe ukuvumela abasebenzisi beLaptop yeLebrem ukuba babone ukuba kukho umntu ophazamise isoftware yekhompyuter xa iqala, isitshixo seLibrem sixhaswa yi I-TPM (Imodyuli yeQonga elithembekileyo) chip eneentloko ezenziwe iyafumaneka kwiLibrem 13 kunye neelaptops ezintsha ze-15.Ngokutsho kwePurism, xa kufakwa isitshixo sokhuselo kukhanyisa okuluhlaza ukubonisa abasebenzisi ukuba ilaptop khange iphazanyiswe ukuze bakwazi ukuthatha apho bebeyeke khona, ukuba ibenye ebomvu Kuthetha ukuba ilaptop iphazamisiwe.
Ukongeza, i-Librem Key izisa amandla okhuseleko akumgangatho ofumanekayo kwiithokheni zokhuseleko, ezinje ngokukwazi ukugcina ukusayinwa kwe-GPG kunye nezitshixo zokubethela ukusetyenziswa kwezixhobo ezininzi, ukukwazi ukugcina izitshixo zokuqinisekisa ze-GPG kwiiseshini ze-SSH, kunye nenkxaso. ukusebenzisa iiPassword zeXesha elinye okanye ukuQinisekiswa kwamanyathelo amabini ukufikelela kwiiwebhusayithi ezahlukeneyo.
Njengoko i-Purism iqhubeka nokuphucula ukhuseleko lweelaptops zaseLibrem kwaye zisebenza nzima ukumilisela i-Librem 5 ekulindelwe kakhulu ngeLinux, inkampani inezicwangciso ezinkulu zeLibrem Key nayo, sele becinga ngokwandisa amandla abo Inkxaso yokufumanisa ukuphazamiseka ngexesha lokuhambisa, phakathi kwezinye izinto ezininzi.
