Trying it out here https://snakeoil.cf Using Apache 2.4 on a server running Jessie, it looks reasonable using just the default ciphers of SSLCipherSuite HIGH:MEDIUM:!aNULL:!MD5. Open to tweaking SSLCipherSuite. Now trying pfs for Postfix, will this email actually use it? On Fri, 2013-09-13 at 08:01 +0200, Eugen Leitl wrote:

With a CA on each freedombox there need not be a requirement for a server.

If my understanding of Tor is right, it is designed for anonymity, not encryption, should not need a CA for this.

Can you get PFS with snakeoil (I presume these are generated during the installation, is there at all enough entropy at that time so this is safe?) certs?

Postfix and dovecot in newer versions can do PFS: http://www.heinlein-support.de/blog/security/perfect-forward-secrecy-pfs-fur... _______________________________________________ Freedombox-discuss mailing list Freedombox-discuss@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/freedombox-discuss
