The default configuration file is openssl.cnf We can't seem to make up our minds:

; find . -name '*.conf' | wc
     79      79    3118
; find . -name '*.cnf' | wc  
     33      33    1064
; 

Should we rename conf to cnf ? Because it will help people understand what's going on better?

(BTW, several files are never used: test/CAssdh.cnf, test/CAssdsa.cnf, test/CAssrsa.cnf, test/Sssdsa.cnf, test/Sssrsa.cnf)
