Setup

create dir to store data

   mkdir -p /var/lib/ssl/{private,keys,certs,newcerts,crl,requests}

echo 01 > /var/lib/ssl/serial touch /var/lib/ssl/index.txt

set directory

• put $dir = /var/lib/ssl/private/ in openssl.cnf

create root cert

openssl req -config /etc/openssl.cnf -new -x509 -keyout /var/lib/ssl/private/cakey.pem -out /var/lib/ssl/certs/cacert.pem

or to init the dir

   ./CA.pl -newcert

   mv newkey.pem /var/lib/ssl/private/cakey.pem ; mv newcert.pem /var/lib/ssl/certs/cacert.pem

Strip the cert

First strip the certificate from all its text to keep only the -CERTIFICATE- section

   openssl x509 -in /var/lib/ssl/certs/cacert.pem -out /var/lib/ssl/certs/cacert.crt
