I-Tesla Motors ishicilele umtapo wezincwadi we-cryptographic we-liblithium, izinjongo eziyinhloko okuwukubumbana, ukusetshenziswa okuphansi kwezinsiza kanye nokuphatheka. Umtapo wolwazi ekuqaleni uthuthukiswa ngeso lokuthi kungenzeka usetshenziswe kokubili kuma-CPU avamile kanye nama-chips e-DSP nama-microcontrollers, futhi ufanelekele ukusetshenziswa ezindaweni ezilinganiselwe nangekhodi ebizwa ngokuthi ezigabeni zokuqala zokuqalisa ukuze kuqinisekiswe amasignesha edijithali e-firmware yedivayisi eshumekiwe. . Ikhodi ibhalwe ngo-C (C99) futhi isatshalaliswa ngaphansi kwelayisensi ye-Apache 2.0.
Umtapo wolwazi usebenzisa amathuluzi okubethela kokusakaza nokusebenza ngamasiginesha edijithali asekelwe esikimini sesivumelwano esingukhiye se-X25519 (RFC 7748), indlela ye-cryptographic permutation ye-Gimli kanye nomsebenzi we-Gimli-Hash we-hash ohlongozwe nguDaniel J. Bernstein futhi ovumela ukusebenza okuphezulu kokuphansi- i-hardware yamandla njengama-microcontrollers angu-8-bit. Ukuqaliswa kwamasiginesha edijithali ye-X25519 kusekelwe kukhodi evela kuhlaka lwe-STROBE futhi kuyahluka kumasiginesha e-ed25519 ngokusebenzisa izixhumanisi ze-"X" kuphela lapho ushintsha amaphuzu ku-elliptic curve, enganciphisa kakhulu usayizi wekhodi edingekayo ukuze udale futhi uqinisekise amasiginesha.
