lists.portside.org SSL certificate using SHA-1 needs revoke/replace

Sensitive: no


The title basically covers the issue, at least as far as I understand it. It appears the cert has SHA-256 and SHA-1 signatures, so perhaps this is an issue with a cert chain? Chrome complains with NET::ERR_CERT_WEAK_SIGNATURE_ALGORITHM, and says both the cert and the chain have SHA-1 signatures.

This appears to be evo.mayfirst.org, which has nothing at all in the Red interface (this is for listserv, so probably understandable).

The SSL cert is a PositiveSSL good through Feb 2019 for lists.portside.org.

I think you can ask PositiveSSL to issue a new cert with a SHA-256 signature, they are usually willing to do this. The other option is for us to setup LetsEncrypt to autogenerate a new cert for lists.portside.org

Let's please go with LetsEncrypt for this service. Thank you!

Ok, I've used mf-certbot to create a new cert for lists.portside.org

I've edited the file /etc/apache2/sites-enabled/lists.portside.org.conf to use the new cert and key and restarted apache2.

        SSLEngine on                                 
        SSLCertificateFile /etc/letsencrypt/live/lists.portside.org/fullchain.pem
        SSLCertificateKeyFile /etc/letsencrypt/live/lists.portside.org/privkey.pem

As far as I can tell apache2 is the only service using tls certs on morales. Is that correct?

morales? Is that the same as evo? I do not know of anything else on there, sorry.

The certs look great now, of course. Thank you!
