#!/usr/bin/make -s
#
# This file is designed to automatize the CA tasks such as:
#  -> init  : create the initial CA tree and the CA root certificate.
#  -> newcsr: create a new private key and csr. $name and $email must be set. C, ST, L, O, OU may be overwitten (example: make newcsr C=FR)
#  -> cert  : sign a pending CSR and generate the certificate. $name must be provided.
#  -> revoke: revoke a certificate. $name must be provided.
#  -> gencrl: update/create the CRL.
#
# The file should be located in the directory STATIC_DIR as defined below.
# The DIR directory will contain the data of the CA. It might be placed in /var.
# The DIR should also be configured in openssl.cnf file under [ CA_default ]->dir.
#
# Here are the steps to install the CA scripts in default environment:
## mkdir /etc/openssl-ca.static
## cp Makefile openssl.cnf /etc/openssl-ca.static
# ( configure the default parameters of your CA in /etc/openssl-ca/openssl.cnf ) ##
## mkdir /etc/openssl-ca
## make -f /etc/openssl-ca.static/Makefile destroy force=y
## cd /etc/openssl-ca
## make init
## make help

       Create private key and csr in clients subdir (named foo.*)\n\
   make cert name=foo\n\
       Signs the CSR foo.csr and creates the certificate foo.cert.\n\
   make revoke name=foo\n\
