## NAME
       make-ssl-cert - Debconf wrapper for openssl

## SYNOPSIS
       **make-ssl-cert** [_OPTION_]... _template_ _output-certificate_
       **make-ssl-cert** **[**_OPTION_]... generate-default-snakeoil

## DESCRIPTION
       make-ssl-cert  is a simple debconf to openssl wrapper to create self-signed certificates.  It
       requires a source template (Ex: /usr/share/ssl-cert/ssleay.cnf) and it  will  place  the  new
       generated certificate in the specified output file.
       Invoked   with   "generate-default-snakeoil",   it   will  generate  /etc/ssl/certs/ssl-cert-
       snakeoil.pem and /etc/ssl/private/ssl-cert-snakeoil.key.

## OPTIONS
       A summary of options are included below.

### --force-overwrite
              Always create a new certificate, even if the file already exists.  For backwards  com‐
              patibility with 1.0.x, this option can be given as last argument, too.

### --no-overwrite
              Never  overwrite  an  existing  file,  even if the old certificate's key length is too
              small or if it uses an obsoltete signature algorithm.

       **--expiration-days** _N_
              Make the new certificate expire in _N_ days.  Default is 3650.
