Verifica se SSL (e/o TLS) funziona:

  • https:
    • openssl s_client  -CApath /etc/ssl/certs -connect www.qualcosa.it:443
  • smtp + TLS (porta 25)
    • openssl s_client  -CApath /etc/ssl/certs -connect mail.qualcosa.it:25 -starttls smtp
  • imap + TLS (porta 143)
    • openssl s_client  -CApath /etc/ssl/certs -connect mail.qualcosa.it:143 -starttls imap
  • pop3 + TLS (porta 110)
    • openssl s_client  -CApath /etc/ssl/certs -connect mail.qualcosa.it:110 -starttls pop3
  • smtps (porta 465)
    • openssl s_client -CApath /etc/ssl/certs -connect mail.qualcosa.it:smtps
  • imaps (porta 993)
    • openssl s_client -CApath /etc/ssl/certs -connect mail.qualcosa.it:imaps
  • pop3s (porta 995)
    • openssl s_client -CApath /etc/ssl/certs -connect mail.qualcosa.it:pop3s

Cambiare la password a una chiave privata

Qeusto comando legge una chiave (crittata o in chiaro, lo capisce da solo guardando dentro al file della chiave) e la critta con la password che scelgo, usando 3des oppure aes256

openssl rsa -des3 -in keyfile.key -out keyfile-with-new-password.key
openssl rsa -aes256 -in keyfile.key -out keyfile-with-new-password.key

Questo comando decritta una chiave e la salva in chiaro:

openssl rsa -in infile.key -out outfile.key

Leggere i dati di un certificato

openssl x509 -in file_certificato.crt -text -noout
