register account
account already exists
1
root@default-ubuntu-1404:/etc/letsencrypt# rm account.key 
root@default-ubuntu-1404:/etc/letsencrypt# /usr/local/bin/letsencrypt.sh register -a account.key -e test@example.org ; echo $?

1
root@default-ubuntu-1404:/etc/letsencrypt# openssl genrsa -out account.key 4096
