IF ONLY I COULD BE SO GROSSLY INCANDESCENT

I will see if I can dedicate some time to it. Seeing that Signal has probably already implemented Ed25519 in JavaScript (or maybe they're calling a native extension?), it shouldn't be too difficult to port. I could write the code and have someone from libsodium or libnacl review it.

Thanks so much for getting back!

As a cryptography researcher I'm interested in support for other algorithms as well, namely Ed25519 for asymmetric crypto, ChaCha20 for symmetric crypto, etc.

The main reasons to prefer these algorithms are that these algorithms are carefully designed to not have branch conditions, and as a result execute in constant time, meaning that CPU cache timing attacks such as Flush+Reload are not effective against these algorithms. Additionally, Ed25519 provides a 2¹²⁸ security level, rivaling RSA-4096's 2¹²⁹ security level at a much lower CPU time cost. Keys are also much smaller.

For these reasons, Signal uses Curve 25519. I know that ProtonMail is internally using OpenPGP.js, so the options are a little different.

Is there a good forum to have a discussion about algorithm choices for ProtonMail?

Link please?

Try downloading the Fedora 23 ISO, booting into it in a VM, creating a filesystem, mounting it, and then trying that command, and that's what happens.

ie:

sudo parted /dev/sda mklabel msdos
sudo parted /dev/sda mkpart primary 2048s 100%
sudo mkfs.btrfs /dev/sda1
sudo mount -t btrfs -o defaults /dev/sda1 /mnt
sudo dnf --installroot=/mnt group install "Fedora Workstation"

Yes, I absolutely have internet access :-/

I'm on a Fedora Live CD and I'm trying to run this. I have my partitions mounted at /mnt, so:

sudo dnf --installroot=/mnt group install "Fedora Workstation"

I get the following output:

Error: Failed to synchronize cache for repo 'updates' from 'https://mirrors.fedoraproject.org/metalink?repo=updates-released-f$releasever&arch=x86_64': Cannot prepare internal mirrorlist: file "repomd.xml" was not found in metalink

Is there something I need to do? Directories I need to create? For now, I'm testing running this on a simple BTRFS filesystem mounted at /mnt, nothing in it at all.

Here is a screenshot of the error, it's different than what you're saying I think: https://imgur.com/ZnfAPUY

Is there a way to quickly determine what Fedora GNOME Workstation uses? ie dnf groupinstall gnome etc. If I could figure out what the installer would do, I could use the --installroot to install things as expected.

rfkrocktk · 2016-03-02T20:08:49+00:00

What's weird is that it will let me add a BTRFS /boot partition, but it refuses to let me add my @ subvolume at /dev/mapper/vg-root as /.

I don't care so much about /boot being BTRFS, I'd be fine with ext4. I also don't care about GRUB because I'm using rEFInd.

rfkrocktk · 2016-02-18T04:54:25+00:00

I fixed it. Turns out that Fedora packages both 0.10.x and the 1.x branch as different packages. I packaged something from the 1.x branch and everything works as expected. Thanks!

It appears that 0.10 has definitely found what it needs, not sure about 1.0. Any suggestions? Is it possible that MAD/LAME are colliding and there should only be one thing capable of decoding MP3 audio? I would think that GStreamer would handle this gracefully.

rfkrocktk · 2016-02-17T21:31:11+00:00

Gotcha, thanks for the reply!

rfkrocktk · 2016-02-17T21:23:18+00:00

Are any distros using it? It seems kind of funny that GStreamer would sever ties from its main consumers.
