|
|
|
||
|
|
ca-renew-cert - renew a previously generated X.509 certificate
|
||
|
|
|
||
|
|
=head1 SYNOPSIS
|
||
|
|
|
||
|
|
B<ca-renew-cert> -t I<type> [B<-f> I<config>] [B<-d> I<days>]
|
||
|
|
I<hostname, username, or path to certificate>

|
||
|
|
|
||
|
|
=head1 DESCRIPTION
|
||
|
|
|
||
|
|
B<ca-renew-cert> renews certificates generated with ca-create-cert(1),
|
||
|
|
extending their validity for a configurable number of days, defaulting to
|
||
|
|
B<CA_CRT_DAYS>.
|
||
|
|
|
||
|
|
=head1 OPTIONS
|
||
|
|
|
||
|
|
B<ca-renew-cert> can infer the correct cached configurations to use for
|
||
|
|
certificate renewal from the hostname of a I<server> or I<client>, the
|
||
|
|
username of a I<user>, or the path to a previously generated certificate of any
|
||
|
|
type.
|
||
|
|
|
||
|
|
=over
|
||
|
|
|
||
|
|
=item B<-t> I<TYPE>, B<--type> I<TYPE>
|
||
|
|
|
||
|
|
This argument is mandatory and tells B<ca-renew-cert> what type of certificate
|
||
|
|
it is renewing, either I<server>, I<client>, or I<user>.
|
||
|
|
|
||
|
|
=item B<-f> I<FILE>, B<--config> I<FILE>
|
||
|
|
|
||
|
|
Load the ca-scripts configuration from I<FILE> instead of
|
||
|
|
I</etc/ca-scripts.conf>.
|
||
|
|
|
||
|
|
=item B<-d> I<DAYS>, B<--days> I<DAYS>
|
||
|
|
|
||
|
|
Renew the certificate to be valid for I<DAYS> days instead of the default
|
||
|
|
B<CA_CRT_DAYS> set in the configuration file.

=head1 BUGS
|
||
|
|
|
||
|
|
B<ca-renew-cert> is currently very careful to re-use the original key and
|
||
|
|
certificate serial when it renews a certificate. This is not strictly necessary
|
||
|
|
for most renewals, and may in fact reduce the long-term security of your SSL
|
||
|
|
certificates.
|
||
|
|
|
||
|
|
The usual renewal process is to re-generate a new CSR and private
|
||
|
|
key with the same DN and sign it as valid for the required time period.
|
||
|
|
This has the unfortunate side-effect of rendering unreadable all S/MIME e-mail
|
||
|
|
and data encrypted with the previous certificate and private key. It will also
|
||
|
|
invalidate any old digital signatures created with the previous certificate.
|
||
|
|
Instead, B<ca-renew-cert> re-signs the old CSR with the same serial and a new
|
||
|
|
validity period, which ensures that no data is lost.
|
||
|
|
|
||
|
|
Arguably, it would be better to support both modes of renewal, and re-generate
|
||
|
|
a new CSR and key for I<server> and I<client> certificates while re-signing old
|
||
|
|
CSRs for I<user> certificates. This may be implemented in future releases.
