Pambuyo pa chaka ndi theka cha chitukuko, kutulutsidwa kwa polojekiti ya VeraCrypt 1.26 kwasindikizidwa, kupanga foloko ya TrueCrypt disk partition encryption system, yomwe yasiya kukhalapo. VeraCrypt ndiyodziwikiratu m'malo mwa RIPEMD-160 algorithm yomwe imagwiritsidwa ntchito mu TrueCrypt ndi SHA-512 ndi SHA-256, kukulitsa kuchuluka kwa ma hashing iterations, kufewetsa njira yomanga ya Linux ndi macOS, ndikuchotsa zovuta zomwe zidadziwika pakuwunika ma code a TrueCrypt. Kutulutsidwa komaliza kwa VeraCrypt 1.25.9 kudasindikizidwa mu February 2022. Khodi yopangidwa ndi polojekiti ya VeraCrypt imagawidwa pansi pa layisensi ya Apache 2.0, ndipo zobwereketsa kuchokera ku TrueCrypt zikupitilizabe kugawidwa pansi pa TrueCrypt License 3.0. Misonkhano yokonzekera imapangidwira Linux, FreeBSD, Windows ndi macOS.
Zina mwa zosintha mu mtundu watsopano:
- Thandizo lowonjezera la kugwiritsa ntchito makhadi anzeru aku banki omwe amatsatira muyezo wa EMV ngati sitolo yayikulu yofikira magawo omwe si adongosolo. Makhadi a EMV angagwiritsidwe ntchito ku VeraCrypt popanda kufunikira kosintha padera gawo la PKCS#11 komanso osalowetsa PIN code. Zomwe zili mufayilo yofunikira zimapangidwira kutengera deta yapadera yomwe ilipo pa khadi.
- Chotsani mawonekedwe a TrueCrypt. Mtundu waposachedwa kwambiri wothandizira kukweza kapena kutembenuza magawo a TrueCrypt ndi VeraCrypt 1.25.9.
- Thandizo la RIPEMD160 ndi GOST89 encryption algorithms lachotsedwa kwathunthu. Magawo opangidwa pogwiritsa ntchito ma aligorivimuwa sangathenso kukhazikitsidwa pogwiritsa ntchito VeraCrypt.
- Pazigawo zokhazikika komanso zobisika zamakina, ndizotheka kugwiritsa ntchito algorithm yatsopano popanga ma pseudo-random sequences (PRF, Pseudo-Random Function), pogwiritsa ntchito BLAKE2s hash function.
- Zosintha mu mtundu wa Linux:
- Kulumikizana bwino ndi kugawa kwa Alpine Linux ndi musl wamba wa C library.
- Kuthetsa nkhani zogwirizana ndi Ubuntu 23.04 ndi wxWidgets 3.1.6+.
- Mtundu wa chimango cha wxWidgets mu ma static assemblies chasinthidwa kukhala 3.2.2.1.
- Kukhazikitsa kwa jenereta ya nambala ya pseudorandom kumayenderana ndi zolembedwa zovomerezeka ndipo ndizofanana ndi zomwe zachitika pa Windows.
- Kukonza cholakwika mu jenereta ya nambala ya pseudorandom yomwe idapangitsa kuti mayeso alephere kugwiritsa ntchito algorithm ya Blake2s.
- Mavuto ogwiritsira ntchito fsck adathetsedwa.
- Vuto posankha kukula kolakwika kwa magawo obisika mukamagwiritsa ntchito njira yogwiritsira ntchito malo onse a disk yatha.
- Konzani kuwonongeka pamene mukupanga magawo obisika kudzera pa mzere wa lamulo.
- Zolakwika zokhazikika pamawonekedwe amtunduwu. Kusankha mafayilo a exFAT ndi BTRFS ndikoletsedwa ngati sizikugwirizana ndi magawo omwe akupangidwa.
- Kugwirizana ndi okhazikitsa akale ogawa akale a Linux kwasinthidwa.
- Malingaliro akhazikitsidwa kuti awonjezere cheke chowonjezera kuti muwonetsetse kuti makiyi a pulayimale ndi achiwiri sakufanana popanga magawo. Chifukwa chogwiritsa ntchito jenereta ya pseudo-random manambala popanga makiyi, makiyi sangatheke ndipo chekecho chidawonjezedwa kuti chithetseretu kuukira kongoyerekeza.
- Pomanga nsanja ya Windows, njira yoteteza kukumbukira imayatsidwa mwachisawawa, zomwe zimalepheretsa njira zomwe zilibe mwayi wowongolera kuti ziwerenge zomwe zili mu kukumbukira kwa VeraCrypt (zitha kusokoneza kuyanjana ndi owerenga pazenera). Chitetezo chowonjezera kuti chisalowe m'malo mwa code mu VeraCrypt ndi njira zina. Kupititsa patsogolo kusungitsa kukumbukira komanso njira yopangira mwachangu zotengera mafayilo. EFI Bootloader yathandizira kuthandizira kwa Windows bootloader yoyambirira mumayendedwe akuwonongeka. Njira yawonjezedwa ku menyu kuti muyike popanda kugwiritsa ntchito cache. Mavuto akuchulukirachulukira kwa encrypt-In-Place encryption m'magawo akulu adathetsedwa. Expander yawonjezera chithandizo chosuntha mafayilo ndi makiyi mumayendedwe akoka & dontho. Nkhani yamakono yosankha mafayilo ndi zolemba zagwiritsidwa ntchito, zomwe zimagwirizana bwino ndi Windows 11. Njira yotsegula ya DLL yotetezedwa yasinthidwa.
- Thandizo lamitundu yakale ya Windows yatha. Windows 10 imanenedwa ngati mtundu wocheperako wothandizidwa.
