Teste simples sobre um site com ssl
Jan 4, 2013 · 8 minute read · CommentsSLdebianportugues
O título é péssimo mas por falta de inspiração fica esse por enquanto.
Estava precisando testar de uma maneira mais simples alguns servidores web com SSL. Anteriormente estava testando manualmente os servidores com o openssl até descobrir o sslscan.
O sslscan testa automaticamente as versões de protocolo (SSLv2, SSLv3, TLS 1.0, etc.), como também testa o tipo de chave criptográfica (cipher) suportado. Ele é muito mais simples do que criar um script usando openssl:
echo -n | openssl s_client -ssl3 -connect www.site.com:443
CONNECTED(00000003)
depth=1 C = ZA, O = Thawte Consulting (Pty) Ltd., CN = Thawte SGC CA
verify error:num=20:unable to get local issuer certificate
verify return:0

Tem muita informação aí, não? Para que eu precisava tinha muita informação pois o que era relevante saber era quais as versões de protocolo e os tipos de chave criptográfica suportado pelo servidores web. Para o teste, usei a opção “–no-failed”.

Também pode usar o COMODO Site Analyzer para testar mas o servidor obrigatoriamente precisar estar disponível na internet.
Obs. Ah… Se você usa Debian é bem simples de instalar:
#aptitude install openssl sslscan
