make-ca is a utility to deliver and manage a complete PKI configuration for
|
2019-04-13 09:23:30 +05:30
|
|
|
workstaitons and servers using only standard Unix utilities, OpenSSL, and
|
|
|
|
p11-kit, using a Mozilla cacerts.txt or like file as the trust source. It can
|
|
|
|
optionally generate keystores for OpenJDK PKCS#12 and NSS if installed. It was
|
|
|
|
originally developed for use with Linux From Scratch to minimize dependencies
|
|
|
|
for early system build, but has been written to be generic enough for any Linux
|
|
|
|
distribution.

The make-ca script will process the certificates included in the certdata.txt
|
2019-04-13 09:23:30 +05:30
|
|
|
file, and place them in the system trust anchors, for use in multiple
|
|
|
|
certificate stores. Additionally, any local certificates stored in
|
|
|
|
/etc/ssl/local will also be imported into the system trust anchors and
|
|
|
|
certificate stores making it a full trust management utiltiy.

As of version 1.2, a p11-kit helper, copy-trust-modifications, is included
|
|
|
|
for use in p11-kit's trust-extract-compat script (which should be symlinked
|
|
|
|
to the user's path as update-ca-certificates). Manual creation of OpenSSL
|
|
|
|
trusted certificates is no longer needed. Instead, import the certificate
|
|
|
|
using p11-kit's trust utility, and recreate the individual stores using the
|
|
|
|
update-ca-certificates script. A copy of any modified anchors will be placed
|
|
|
|
into $LOCALDIR (in the correct format) by the p11-kit helper script.
|
|
|
|
|
|
|
|
For the p11-kit distro hook, remove the "not configured" and "exit 1" lines
|
|
|
|
from trust/trust-extract-compat.in, and append the following:
|
|
|
|
===============================================================================
|
|
|
|
# Copy existing modifications to local store
|
|
|
|
/usr/libexec/make-ca/copy-trust-modifications
|
|
|
|
|
|
|
|
# Generate a new trust store
|
|
|
|
/usr/sbin/make-ca -f -g

If you wish to distribute the results of this script as a standalone package,
|
|
|
|
unlike in the BLFS distribution for which it was originally written, where the
|
|
|
|
end user is ulimately responsible for the content, you, as the distributor, are
|
|
|
|
taking ownership for the results. You are strongly encouraged to define a
|
|
|
|
written inclusion policy, distribute all blacklisted files as a part of the
|
|
|
|
local directory, and to provide the written policy in the distributed package.

The manual instructions below have been left for reference.

|
|
|
|
|
|
To create an OpenSSL trusted certificate from a regular PEM encoded file,
|
|
|
|
provided by a CA not included in Mozilla's certificate distribution, you need
|
|
|
|
to add trust arguments to the openssl command, and create a new certificate.
|
|
|
|
There are three trust types that are recognized by the make-ca.sh script,
|
|
|
|
SSL/TLS, S/Mime, and code signing. For example, using the CAcert root, if you
|
|
|
|
want it to be trusted for all three roles, the following commands will create
|
|
|
|
an appropriate OpenSSL trusted certificate:
|
|
|
|
|
|
|
|
# install -vdm755 /etc/ssl/local &&
|
|
|
|
# wget http://www.cacert.org/certs/root.crt &&
|
|
|
|
# openssl x509 -in root.crt -text -fingerprint -setalias "CAcert Class 1 root" \
|
|
|
|
-addtrust serverAuth -addtrust emailProtection -addtrust codeSigning \
|
|
|
|
> /etc/ssl/local/CAcert_Class_1_root.pem
|
|
|
|
|
|
|
|
If one of the three trust arguments is omitted, the certificate is neither
|
|
|
|
trusted, nor rejected for that role. Clients that use OpenSSL or NSS
|
|
|
|
encountering this certificate will present a warning to the user. Clients using
|
|
|
|
GnuTLS without p11-kit support are not aware of trusted certificates. To
|
|
|
|
include this CA into the ca-bundle.crt (used for GnuTLS), it must have
|
|
|
|
serverAuth trust. Additionally, to explicitly disallow a certificate for a
|
|
|
|
particular use, replace the -addtrust flag with the -addreject flag.
|
|
|
|

|
Local trust overrides are handled entirely using the /etc/ssl/local directory.
|
2017-09-21 11:10:23 +05:30
|
|
|
To override Mozilla's trust values, simply make a copy of the certificate in
|
2017-09-21 11:09:18 +05:30
|
|
|
the local directory with alternate trust values.
