O Cryptsetup, em combina\u00e7\u00e3o com o driver hfsplus, agora pode abrir unidades USB criptografadas com FileVault2 em modo de leitura e grava\u00e7\u00e3o em sistemas com um kernel Linux padr\u00e3o. O acesso a unidades com o sistema de arquivos HFS+ e com parti\u00e7\u00f5es Core Storage \u00e9 suportado (parti\u00e7\u00f5es com APFS ainda n\u00e3o s\u00e3o suportadas).\n<li class=\"l\"> A biblioteca libcryptsetup foi liberada do bloqueio global de toda a mem\u00f3ria atrav\u00e9s da chamada mlockall(), que era usada para prevenir vazamentos de dados confidenciais para a parti\u00e7\u00e3o de troca. Devido \u00e0 supera\u00e7\u00e3o do limite para o tamanho m\u00e1ximo de mem\u00f3ria bloqueada quando executado sem privil\u00e9gios de root, na nova vers\u00e3o foi aplicada uma sele\u00e7\u00e3o de bloqueio apenas nas \u00e1reas de mem\u00f3ria onde s\u00e3o armazenadas as chaves de criptografia.\n<li class=\"l\"> A prioridade dos processos que geram a chave (PBKDF) foi aumentada.\n<li class=\"l\"> Adicionadas fun\u00e7\u00f5es para adicionar tokens LUKS2 e chaves bin\u00e1rias ao slot de chaves LUKS (keyslot), al\u00e9m das frases de senha e arquivos de chave j\u00e1 suportados anteriormente.\n<li class=\"l\"> Possibilidade de extrair a chave da parti\u00e7\u00e3o usando uma frase de senha, um arquivo de chave ou um token foi disponibilizada.\n<li class=\"l\"> A op\u00e7\u00e3o &#171;&#8212;use-tasklets&#187; foi adicionada ao veritysetup, permitindo um aumento de desempenho em alguns sistemas com o kernel Linux 6.x.      <\/ul>\n<p>Fonte: <a
