Topic: TLSv1.2 with #define NO_DH
Hi,
I am using wolfssl ver 3.1.3 and wolfMQTT 1.1.0 with TLSv1.2 on microchip.
Can TLS1.2 run with #define NO_DH being used?
Thanks,
Gil

Hi Gil,
Yes you can disable DH if you are using ECC or a static cipher suite.

Hi,
Whats is application level difference in using DH and ECC? What is the effect of disabling DH? and in which file should we do #define NO_DH?
Hi rahila_shams,
The difference between DH and ECC is the asymmetric algorithm used for securely deriving a shared secret. If DH is disabled only ECDH(E) cipher suites are available.
For setting the build option I recommend using our user_settings.h and WOLFSSL_USER_SETTINGS to define NO_DH. See our first FAQ item here: https://www.wolfssl.com/docs/frequently … r_wolfSSL?
Thanks,
