VPN: Script para a criação de perfis OpenVPN

O script seguinte permite criar um perfil para um cliente OpenVPN após serem criados os seus certificados e chaves (./build-key tabuleta).

Deve ser guardado em /etc/openvpn/easy-rsa/keys/mergeKeys.sh

E deve ser invocado a partir dessa localização com o argumento do nome do cliente. Por exemplo:
./mergeKeys.sh tabuleta

Para criar tabuleta.ovpn, a partir de ca.crt, tabuleta.crt e tabuleta.key.

Deve copiar-se o perfil de exemplo OVPN para template.ovpn e configurá-lo de acordo com o servidor.
