Comment: navajos is less bad than it seems, deleuze is really as bad as it seems

1. Heartbleed Aftermath
Fortunately HCoop wasn't hit by the OpenSSL Heartbleed bug. However this perhaps is an opportunity for some spring clean up.
These reports do not look good:
(Warning: their analyzer may need to run, and you might need to wait a while to see the actual report.)
Here's the status of navajos: it gets an F per the above SSL Labs report, because:
- Server's certificate is not trusted. Grade set to F. Ignoring certificate problems, it gets a C.
- Server supports only older protocols, but not the current best TLS 1.2. Grade capped to B.
- Server does not support Forward Secrecy with the reference browsers.
Deleuze is particularly problematic, because:
- Server's certificate is not trusted. Grade set to F. Ignoring certificate problems, it still gets an F.
Server supports SSL 2, which is obsolete and insecure. Grade set to F.--) Fixed
- Server is vulnerable to MITM attacks because it supports insecure renegotiation. Grade set to F.
- Server does not mitigate the CRIME attack. Grade capped to B.
- Server supports only older protocols, but not the current best TLS 1.2. Grade capped to B.
- There is no support for secure renegotiation.
- Server does not support Forward Secrecy with the reference browsers.
Since deleuze is scheduled to be decommissioned, we might want to focus on the remaining problems.
1.1. CA Certification
Problem: Browsers do not trust HCoop's self-signed certificate. Potential members might be scared away by big honking browser warnings. We might want to get a "proper" CA-signed certificate; perhaps a wildcard one. But these tend to be fairly expensive.
These are the choices at the moment, to solve the immediate problem in an inexpensive manner:
Gandi offers one-year free CA certificate with domain registrations.
StartSSL offers free CA certificates, but charges $25 for revocations.
1.2. Perfect Forward Secrecy
Forward Secrecy is being advocated as a solution that offers stronger protection for private keys; evidently it is straightforward to enable with Apache.
