Changes for SSL / certificates handling

[Marc Worrell]

Hi,

We have just merged a change to the certificate handling in master.

There is now a “security” directory.

In this directory we now store the DH file and all certificates.

It is normally located in ~/.zotonic/security

Use "bin/zotonic config” to see where the security directory is located.

This directory is shared between all running Zotonic instances.

It has subdirectories:

 * security/self-signed/…  holding all self-signed certificates

 * security/sitename/ca/… holding any CA supplied certificate for the given site

 * security/sitename/letsencrypt/… Let’s Encrypt certs for the given site

USING YOUR CURRENT CERTIFICATES

Rename priv/ssl to priv/security and you will be ok for letsencrypt and ca.

Cheers, Marc
