SSL cipher suites, esp hangs up
Posted: Mon Mar 13, 2017 4:14 pm
Hello,
i tried to test the openssl_server example with different cipher suites. I used openssl s_client on Linux.
e.g. openssl s_client -connect 192.168.43.75:443 -cipher DHE-RSA-AES256-GCM-SHA384
Most of the ciphers work, some don't accept but for some the esp32 hangs up in the ssl connection buildup process.
I don't have a problem with the ciphers not working, but it is not good if the esp32 hangs up for some cipher suites.
The ciphers where it stopped working:
DHE-RSA-AES256-GCM-SHA384
DHE-RSA-AES256-SHA256
DHE-RSA-AES256-SHA
DHE-RSA-CAMELLIA256-SHA
DHE-RSA-AES128-GCM-SHA256
DHE-RSA-AES128-SHA256
DHE-RSA-AES128-SHA
DHE-RSA-CAMELLIA128-SHA
EDH-RSA-DES-CBC3-SHA
Any Ideas how to solve this or is it a bug?
Best Regards
