Gergely Harmadás commented on KAFKA-20997:
------------------------------------------

[~mimaison] I know it is not exactly the same but I have faced a similar 
TLS-related issue with FIPS. Usually those environments operate with a 
restricted set of ciphers which can cause issues if an unsupported cipher ends 
up in the broker config. My proposed solution in KAFKA-20676 also follows the 
same pattern, instead of a hard crash at startup the broker would continue as 
long as there is at least one supported cipher in {*}ssl.cipher.suites{*}. 
Might be worth linking the two JIRAs together.

> The default SSL engine factory implementation statically loads a KeyFactory 
> for the DSA algorithm at startup. This prevents brokers from stating in FIPS 
> environments where DSA is not available.
> Instead of failing at the key factory creation, broekrs should ignore key 
> factories that can't be loaded (just log a message) and only fail if a key 
> requires a factory that wasn't loaded.
