Hi Matt,

Today new vulnerabilities with (3)DES and BlowFish were made public and 
I believe we'll see release of another paper which is OpenSSL 1.1 
related with the release of OpenSSL 1.1.0. I have no knowledge if the 
paper/report contained vulnerabilities that have postponed the release 
of 1.1.0 but I think that is likely. That would mean that these 
vulnerabilities have been solved pre-release.

As far as I know x25519 is still a Draft RFC so unlikely to appear in 
browsers for a while. I can see LibreSSL adding this as well, whether in 
the draft version or in the final. This they did with ChaCha20/Poly1305 
as well (draft in 2.3, release in 2.4). The LibreSSL devs would have 
closed the request if they didn't intend to support it 
https://github.com/libressl-portable/portable/issues/114

I don't think that FreeBSD will be making LibreSSL the libssl/libcrypto 
provider any time soon. The support timelines for LibreSSL (<1.5 years) 
are just too short for the FreeBSD release support (>3 years). OpenSSL 
is speeding up the release cycle as well but at least we can rely on 
RedHat to backport changes to older versions.

LibreSSL in base is a bit more than playing, it is becoming the default 
in HardenedBSD very soon and very likely in TrueOS (AKA PC-BSD) as of 
11.0 RELEASE. Both HardenedBSD and TrueOS have a different attitude 
towards updating things in the base system as they do not serve as 
upstream to other projects/products that require longer support 
timelines. Come see my talk at EuroBSDCon, it will contain LibreSSL in 
base things.

Cheers,

Bernard.
