Na nova vers\u00e3o, a ferramenta scp foi alterada para usar SFTP por padr\u00e3o, ao inv\u00e9s do obsoleto protocolo SCP\/RCP.       <\/p>\n<p>No SFTP, m\u00e9todos de manipula\u00e7\u00e3o de nomes mais previs\u00edveis s\u00e3o aplicados, e o processamento de padr\u00f5es globais em nomes de arquivos atrav\u00e9s do shell no outro host, que pode criar problemas de seguran\u00e7a, n\u00e3o \u00e9 utilizado. Especificamente, ao usar SCP e RCP, o servidor decide quais arquivos e diret\u00f3rios enviar ao cliente, enquanto o cliente apenas verifica a corre\u00e7\u00e3o dos nomes dos objetos retornados, o que, na aus\u00eancia de verifica\u00e7\u00f5es adequadas do lado do cliente, pode permitir <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/pt\/server\/dts-shicago\/\"   title=\"servidor\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"2910\">servidor<\/a> o envio de outros nomes de arquivos que diferem dos solicitados.     <\/p>\n<p>O protocolo SFTP n\u00e3o possui os problemas mencionados, mas n\u00e3o suporta a expans\u00e3o de caminhos especiais, como '~\/'. Para resolver essa diferen\u00e7a, a partir do OpenSSH 8.7, a implementa\u00e7\u00e3o do servidor SFTP suporta a extens\u00e3o do protocolo 'expand-path@openssh.com' para a expans\u00e3o dos caminhos ~\/ e ~user\/.     <\/p>\n<p>Ao usar o SFTP, os usu\u00e1rios tamb\u00e9m podem enfrentar incompatibilidades devido \u00e0 necessidade de dupla escape de caracteres especiais de expans\u00e3o de caminhos em solicita\u00e7\u00f5es SCP e RCP, para evitar que sejam interpretados no lado remoto. No SFTP, essa necessidade de escape n\u00e3o existe e aspas extras podem causar erro na transfer\u00eancia de dados. Os desenvolvedores do OpenSSH optaram por n\u00e3o adicionar extens\u00e3o para replicar o comportamento do scp nesse caso, pois o duplo escape \u00e9 considerado uma defici\u00eancia que n\u00e3o vale a pena repetir.    <\/p>\n<p>Outras mudan\u00e7as na nova vers\u00e3o:  <\/p>\n<ul>\n<li class=\"l\"> No ssh e sshd, o algoritmo de troca de chaves h\u00edbrido 'sntrup761x25519-sha512@openssh.com' (ECDH\/x25519 + NTRU Prime) est\u00e1 ativado por padr\u00e3o, resistente a ataques de computadores qu\u00e2nticos e combinado com ECDH\/x25519 para bloquear poss\u00edveis problemas no NTRU Prime que possam surgir no futuro. O algoritmo mencionado agora est\u00e1 em primeiro lugar na lista de KexAlgorithms, que define a ordem de sele\u00e7\u00e3o dos m\u00e9todos de troca de chaves, sendo mais priorit\u00e1rio do que os algoritmos ECDH e DH.\n<p>Os computadores qu\u00e2nticos ainda n\u00e3o alcan\u00e7aram um n\u00edvel que permita quebrar chaves tradicionais, mas a aplica\u00e7\u00e3o de prote\u00e7\u00e3o

quando os computadores qu\u00e2nticos necess\u00e1rios estiverem dispon\u00edveis.    <\/p>\n<li class=\"l\"> Uma nova extens\u00e3o 'copy-data' foi adicionada ao sftp-server, permitindo copiar dados
