Podr\u017eano je kori\u0161tenje s particijama dm-crypt, LUKS, LUKS2, BITLK, loop-AES i TrueCrypt\/VeraCrypt. Paket tako\u0111er uklju\u010duje alate veritysetup i integritysetup za postavljanje sredstava kontrole integriteta podataka temeljenih na modulima dm-verity i dm-integrity.    <\/p>\n<p>Klju\u010dna pobolj\u0161anja:  <\/p>\n<ul>\n<li class=\"l\"> Implementirana je mogu\u0107nost kori\u0161tenja hardverskog mehanizma enkripcije diskova OPAL, koji se podr\u017eava na samoshifriraju\u0107im (SED - Self-Encrypting Drives) SATA i NVMe ure\u0111ajima s OPAL2 TCG su\u010deljem, u kojima je ure\u0111aj za hardversku enkripciju integriran izravno u kontroler. S jedne strane, enkripcija OPAL ovisi o proprietary opremi i nije dostupna za javnu reviziju, no s druge strane, mo\u017ee se koristiti kao dodatni sloj za\u0161tite iznad softverske enkripcije, ne uzrokuju\u0107i smanjenje performansi i ne stvaraju\u0107i optere\u0107enje na CPU.\n<p>Za kori\u0161tenje OPAL-a u LUKS2 potrebna je verzija Linux jezgre s opcijom CONFIG_BLK_SED_OPAL i uklju\u010divanje u Cryptsetup (podrazumijevano je podr\u0161ka za OPAL isklju\u010dena). Konfiguracija LUKS2 OPAL-a provodi se po analogiji sa softverskom enkripcijom - metapodaci se pohranjuju u zaglavlju LUKS2. Klju\u010d se dijeli na klju\u010d particije za softversku enkripciju (dm-crypt) i klju\u010d za otklju\u010davanje za OPAL. OPAL se mo\u017ee koristiti kako zajedno sa softverskom enkripcijom (cryptsetup luksFormat -hw-opal ), tako i odvojeno (cryptsetup luksFormat -hw-opal-only ). Aktivacija i deaktivacija OPAL-a vr\u0161i se na isti na\u010din (open, close, luksSuspend, luksResume) kao i za ure\u0111aje LUKS2.    <\/p>\n<li class=\"l\"> U plain modu, u kojem se glavni klju\u010d i zaglavlje ne pohranjuju na disku, podrazumijevano je anga\u017eiran \u0161ifriraju\u0107i algoritam aes-xts-plain64 i hash algoritam sha256 (umjesto CBC moda, koji ima probleme s performansama, anga\u017eiran je XTS, a umjesto zastarjelog hasha ripemd160 - sha256).\n<li class=\"l\"> U komandama open i luksResume dopu\u0161teno je pohranjivanje klju\u010da particije u odabranom korisni\u010dkom skladi\u0161tu klju\u010deva u jezgru (keyring). Za pristup keyringu mnogim komandama cryptsetup dodana je opcija \"--volume-key-keyring\" (npr. 'cryptsetup open  --link-vk-to-keyring \"@s::%user:testkey\" tst').\n<li class=\"l\"> Na sustavima bez swap particije, prilikom formatiranja ili kreiranja klju\u010deva za PBKDF Argon2, sada se koristi samo polovica slobodne memorije, \u0161to je rije\u0161ilo problem iscrpljivanja dostupne memorije na sustavima s malom koli\u010dinom RAM-a.\n<li class=\"l\"> Dodana je opcija \"--external-tokens-path\" za navo\u0111enje direktorija za vanjske rukovaoce tokena LUKS2 (pluginove).\n<li class=\"l\"> U tcrypt je dodana podr\u0161ka za hashing algoritam Blake2 za VeraCrypt.\n<li
