Bronze ITLS Fundamentals Ep.8 - Final Challenge
Hello together,
i am stuck in the TLS Fundamentals final challenge at question 14. The question
"Use the cipher suite DHE-RSA-AES128-SHA256 to connect on the port number found in the previous answer using TLS v1.2. What is the size of the Diffie-Hellman "Temp Key" used?"
If i am connecting to the local host with this command:
openssl s_client -connect localhost:8443 -cipher DHE-RSA-AES128-SHA256 -tls1_2
I get a connection fail, but if i use tls1_3, connection is working. But the found temp key value of 253 bits is not correct. Could you maybe guide me, where my mistake is?
Benjamin
Hi Benjamin,
Your command is correct. The only problem with it is the port number. Based on the previous question, the port number is in the cert chain. I hope that helps.
