Cert-Gen-CLI

Code from https://utilities.govroam.uk/certs for generating eduroam/Govroam SSL certs.

These certs are specifically designed to work well with eduroam/Govroam and include all the features required to ensure that as many clients as possible are compatible.

This is the command line version, which can be installed locally and run securely (it's not advisable to use the website for production as Jisc can't guarantee the security of the information entered or returned).

Install

git clone http://gitlab.perpetual.name/doctor/certgencli.git CertGenCLI

cd CertGenCLI

Either install the python cryptography package

apt-get install python-cryptography

or

pip install -r requirements.txt

The latter doesn't appear to work too well on Debian.

Run

cli.py -c -s -l -o -ou -n -r -p -d

e.g. ./cli.py -d /tmp -n fred.site.com -cGB -sWales -lCardiff -oSomewhere -uSomething -pakjdslfasd

This will create all the necessary certificates in /tmp

rootca.pem server-cert.pem server-key.pem list.crl root-key.pem

RootCA

To be installed on the client, as a trusted Root Certificate. If using the CAT, upload this when creating a profile and set the "Name (CN) of Authentication Server" to idp.westeros.zz. It can be pushed out to clients via a policy, or downloaded in 'mobileconfig' files or published on a web site

Server Cert

To be installed on the RADIUS IdP. Put this, along with the Server Key below, on to your RADIUS server and configure as part of the EAP security. Do not install the above Root CA on the server.

Server Key

To be installed on the RADIUS IdP, as above.

CRL

Publish at the URL https://idp.westeros.zz/list.crl. It should be accessible by all clients. Whilst not necessary for clients to authenticate it reduces the risk of some clients rejecting the authentication.

RootCA Key

To be kept safe, along with the password used, and is required for any future server certificates, or to change the CRL

Notes

You can check the certificates by running:

openssl x509 -noout -text -in

which will work for rootca.pem and server-cert.pem

openssl rsa -in -check

which will work for server-key.pem and root-key.pem

openssl crl -noout -text -in

which will work for list.crl

The default password is 'something'.
