Dear List, 1) cd /home/user/Desktop 2) /usr/lib/ssl/misc/CA.pl -newca 3) openssl req -new -nodes -x509 -keyout ca.key -out ca.crt -days 3650 4) openssl req -new -nodes -keyout key.key -out key.req 5) openssl ca -policy policy_anything -days 3650 -out key.crt -infiles key.req I created certificates needed for sslbump from the process as cited over here http://www.techienuggets.com/commentList.jsp?tx=48105&tx=48105&d-49653-p=2 In my earlier step i just ran 3,4,5 step which resulted in 5 step generating an error,so i had to bring in the 2nd step. It generated 5 files ca.key, ca.crt, key.key, key.req, key.crt and a folder named demoCA,i have already used a)ca.crt with key.key b)ca.crt with key.crt c)key.crt with key.key combinations but unable to succeed in the command https_port 3129 transparent sslBump cert= key= resulting into Failed to acquire SSL certificate error. Any ideas? Thanks In Advance, Anand Your Mail works best with the New Yahoo Optimized IE8. Get it NOW! http://downloads.yahoo.com/in/internetexplorer/
