CirrusCipher Suite: Disable DHE / EDH?
Hi
does somebody know how to disable DHE/DSS and EDH/RSA KeyX Algorithms?
Thanks, Rolf

Try this one?
tmm --clientciphers '!DTLSv1:!RC4:!DHE:DEFAULT:@SPEED'
rolfThanks for the hint! In addidtion by disabling SHA is should be ok:

I think you can edit on ssl profile to use only encryptions which you want to.
Something like:
ciphers DEFAULT:RSA+AES-GCM:RSA+AES:@STRENGTH
