Kutulutsidwa kwa VeraCrypt 1.24, foloko ya TrueCrypt

Pambuyo pa chaka cha chitukuko losindikizidwa kutulutsidwa kwa polojekiti VeraCrypt 1.24, yomwe imapanga foloko ya TrueCrypt disk partition encryption system, anaima kukhalapo kwanu. 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. mavutoodziwika panthawi ya ndondomekoyi kafukufuku TrueCrypt source code. Nthawi yomweyo, VeraCrypt imapereka mawonekedwe ofananira ndi magawo a TrueCrypt ndipo ili ndi zida zosinthira magawo a TrueCrypt kukhala mtundu wa VeraCrypt. Code yopangidwa ndi polojekiti ya VeraCrypt wogawidwa ndi pansi pa chilolezo cha Apache 2.0, ndikubwereka ku TrueCrypt pitilizani zoperekedwa pansi pa TrueCrypt License 3.0.

M'kutulutsa kwatsopano:

• Kwa magawo omwe si adongosolo, kutalika kwa mawu achinsinsi kwakwezedwa mpaka zilembo 128 mu encoding ya UTF-8. Kuonetsetsa kuti zimagwirizana ndi machitidwe akale, njira yawonjezeredwa kuti muchepetse kukula kwachinsinsi kwa zilembo za 64;
• Thandizo la library lawonjezedwa ngati njira ina ku malangizo a CPU RDRAND Jitterentropy, yomwe imagwiritsa ntchito jitter pakupanga ma hardware a manambala achinyengo, kutengera kupotoza kwa nthawi yobwerezanso ya malangizo ena pa CPU (CPU execution time jitter), zomwe zimadalira zinthu zambiri zamkati komanso zosayembekezereka popanda kulamulira thupi pa CPU;
• Kukhathamiritsa kwa magwiridwe antchito kwapangidwira mawonekedwe a XTS pamakina a 64-bit omwe amathandizira malangizo a SSE2. Kukhathamiritsa kwapakati kumachulukitsa zokolola ndi 10%;
• Khodi yowonjezeredwa kuti muwone ngati CPU imathandizira malangizo a RDRAND/RDSEED ndi ma processor a Hygon. Mavuto pozindikira thandizo la AVX2/BMI2 atha;
• Kwa Linux, "--import-token-keyfiles" njira yawonjezedwa ku CLI, yogwirizana ndi mawonekedwe osagwiritsa ntchito;
• Kwa Linux ndi macOS, cheke cha kupezeka kwa malo aulere mu fayilo yamafayilo kuti agwirizane ndi chidebe cha fayilo chopangidwa chawonjezedwa. Kuti mulepheretse cheke, mbendera ya "-no-size-check" imaperekedwa;
• Kwa Windows, njira yakhazikitsidwa posungira makiyi ndi mapasiwedi kukumbukira mu mawonekedwe obisika pogwiritsa ntchito ChaCha12 cipher, t1ha hash ndi CSPRNG kutengera ChaCha20. Mwachikhazikitso, njirayi imayimitsidwa, chifukwa imakwera pamwamba pafupifupi 10% ndipo sichilola kuti dongosololi liyike mumayendedwe ogona. Kwa Windows, chitetezo kuzinthu zina zochotsa kukumbukira zawonjezedwa, kutengera kukhazikitsa mu KeePassXC njira yoletsa mwayi wokumbukira kwa ogwiritsa ntchito omwe alibe ufulu woyang'anira. Onjezani makiyi otsegula musanatseke, musanayambitsenso, kapena (mwakufuna) polumikiza chipangizo chatsopano. Kusintha kwapangidwa ku UEFI bootloader. Thandizo lowonjezera pakugwiritsa ntchito malangizo a CPU RDRAND ndi RDSEED ngati gwero lina la entropy. Anawonjezera phiri mode popanda kupatsa kalata kugawa.
