TMUI / Configuration WebUI - TLS/SSL Configuration - ECDHE
- Dec 21, 2017
But the point being is that the command sys httpd ssl-ciphersuite on 11.6.x, doesn't seem to then correctly configure Apache services to use this for the TMUI.
i understand this has been corrected in 12.0.
Hi JD,
It is possible to disable all cipher suites other than the ones using ECDHE by appending ':!kDH:!kEDH:!kRSA' (without the quotes) to your cipher string within httpd. That should disable all DH, EDH/DHE, RSA key exchange based cipher suites. We need to specify the 'k' when enabling/disabling a certain key exchange when you modify the string on httpd, as it's based on the openssl stack. When enabling/disabling them within the SSL profiles, you don't need to specify that, because that is natively built into TMM and you can simply specify ':!DHE:!DH:!RSA' (without the quotes) to disable those key exchange based cipher suites.
Please let me know if this answers your question.
Hi Ashwin,
Thanks for the reply.
ECDHE needs to be there to begin with though, and isn't. It looks like 12.x does have it when I took it to lab. But I currently need it in 11.6.2.
As for SSL profiles, I'm not looking at/referring to SSL profiles as this is outside of TMM and is Apache via mod_ssl (configured via the sys httpd ssl-ciphersuites).
If there's anyway to enable ECDHE for Apache/Mod_SSL on 11.6.2, I'm all ears.
Thanks,
JD
