STILL A NEWBIE TO UBUNTU , please excuse if it is a silly question.
Foi-me pedido que deixasse de apoiar as cifras TLS1.0. Googled e descobri que adicionando linha abaixo para ssl.conf pode remover TLS1.0 do httpd:
SSLProtocol all -TLSv1
Existe um "sslscan" no kali linux que estou usando para escanear o ip com a porta 443 para listar as cifras suportadas por esse ip.
Agora, antes de remover a cifra TLS1.0, o SSLSCAN funcionou corretamente e deu os resultados adequados conforme abaixo:
TLS renegotiation:
Session renegotiation not supported
TLS Compression:
Compression disabled
Heartbleed:
TLS 1.0 not vulnerable to heartbleed
TLS 1.1 not vulnerable to heartbleed
TLS 1.2 not vulnerable to heartbleed

Failed to connect to get certificate.
Por que depois de remover as cifras TLS1.0, o sslscan não consegue se conectar para obter certificados? Estou removendo o TLS1.0 errado? Se sim, qual é a maneira correta de desabilitar / remover as cifras TLS1.0? Ou isso é normal? O sslscan usa apenas o TLS1.0 para escanear o ip com a porta 443 que eu havia desativado, ou seja, ele não está conseguindo obter o certificado?
Além disso, deixe-me saber se esta questão está fora do tópico aqui, pq estou usando o kali para sslscan.
