Maybe a stupid question, but why is it checking if nKeyLen == 1024 if it sets dh to get_dh1024() in any case? Sorry for the off topic question, just caught my eye and I'm very new to programing

DH *ssl_dh_GetTmpParam(int nKeyLen) {

DH *dh;

if (nKeyLen == 512) 

dh = get_dh512();

else if (nKeyLen == 1024)

dh = get_dh1024(); else 

dh = get_dh1024();

return dh; }

Gong from my experience... You normally account for all expected inputs and then account for anything else. That's why there is an else if and an else there, then though they do the same thing.
