It’s never a bad idea to update SSH keys regularly - even better when there is a more secure algorithm. 🙂

@@Johan.Molenberghs I'd think that this would only be necessary if you have really bad security hygiene; dropping your keys onto every machine that you touch.

Love SSH... fast, secure, can do file transfers easily multiple ways... and can trivially be centrally managed with a key server. That might be an idea for a vid too: Key servers. Edited to add: I mean e.g. LDAP vs universal key managers vs simple inotify to copy pub keys to servers that kind of thing. More than one way to skin SSH. :)

[@Andrath]

Uhm no. The whole point of the SSH key system is to easily create and distribute keys. The ed25519 keys are short so they are perfect, Look into ssh-copy-id. There is probably a manpage. You can just publish those keys pretty much anywhere. Hey, you could piggyback them on the GnuPG keyservers as a comment.

That's such an awesome skill for a teacher to have and I'm so glad you enjoy what you do!

[@james_neko]

There's also different curves or curve parameters. As I understand it, ECDSA uses some curves published by NIST, where they say "Use these curve parameters" without any particular justification, and people speculate the NSA may be involved in getting them to endorse those particular parameters. The Curve25519 curve used by Ed25519 is also allegedly maybe more secure when it comes to side-channel attacks? But at this point I'm beyond my ability to assertively repeat that information.

[@ben_spiller]

The NIST curves are suspect because some of the parameters are randomly generated. NIST publishes the seeds used for the random number generator, but no explanation how they came up with the seeds (they look random). They could have used a nothing-up-my-sleeve number but they didn't.

[@Acorn_Anomaly]

One thing that might be cool to cover in the future is SSH certificates. They're built in to OpenSSH, with commands for managing them built in to ssh-keygen. But they're useful because they allow you to essentially create auto-trusted, but auto-expiring keys for any user on the system. You can limit the authorization for the certificate to specific dates/times, specific users, even specific uses of SSH. One benefit is not needing to reconfigure the target system with an updated authorization when a new key is created. As long as a new cert is generated, and signed by a key trusted by the target, the new cert will be accepted, without needing to update authorized_keys. And the "CA key" trust can be specified by the authorized_keys file or by a config option in sshd_config.

[@dieselbaby]

Yup, you can combine this kind of thing with something like Keybase and use it to manage your own custom CA for key management, it's fantastic.

[@jarrodurban6927]

Great news. I am happy about the change. The length of the public keys make a practical difference. The new keys fit on one line, and are easy to copy and paste.

Thanks for the video! Somewhere in enterprise RSA is still requirement, on modern systems too. "Azure currently supports SSH protocol 2 (SSH-2) RSA public-private key pairs with a minimum length of 2048 bits. Other key formats such as ED25519 and ECDSA are not supported."

[@davidjohnston4240]

Enterprise deployments tend to chase FIPS compliance and Ed25519 is not quite there yet with NIST. The NIST curves like P256 are trusted by no one but still used as the least bad option unless you consider RSA the least bad option. Everyone is annoyed with NIST about them taking so long to get the whole Ed25519 certification cake baked.

[@aysnov]

RSA *is* the least bad option. Even if you're willing to use crypto parameters from a three-letter agency, non-ed ECDSA is a giant footgun.

[@davidjohnston4240]

​@aysnov RSA is resource intensive compared to the others. It scales poorly too. NIST aren't even working on writing up the ed25519 specs which tells you that they are doing thier best to delay its adoption.

[@aysnov]

I'd argue "resource intensive" beats "leaks your private key if you ever use it with poor RNG". Key exchange performance shouldn't really matter on anything reasonably modern anyway, short of maybe some very constrained embedded systems.

[@davidjohnston4240]

​@aysnov A poor RNG is never going to be a problem for me (My job). But my primary concern is the side channel and fault injection properties. RSA sucks more than EC in that respect, but the side channel research changes pretty fast so it might be less true over time. Small devices (eg smart cards) have issues with computing large RSA operations. The intersection of good algorithms and NIST compliant algorithms is nothing.

Hi, new subscriber, but ooold S/W guy here. Coupla things: I work for a contractor at a US Gov't agency known throughout the solar system (ahem).

Given a choice, I'll use ed25519 key pairs; I trust djb a whole lot more than I do NIST. The other thing: My spouse and I had Power Computing machines in the brief window when Apple allowed clones, before the Second Coming of Jobs.

That's not for her to say, not you. =) It is fair for me to say that I need to hear what she's saying. As mentioned, I do use the closed captioning and that does indeed help! You're right that I'm requesting reasonable accommodation, like asking a spouse to use a lower shelf in the kitchen, or a phone app to allow the setting of larger font sizes to ease readability. I'd like to think that we don't (yet) live in a world in which we tell others that they should just go buy a ladder or rely on screen readers. Veronica puts a great deal of effort in taking complex, detail oriented topics and delivering content that is both accurate and nuanced. She also certainly puts considerable thought into delivery style as well and modulates her voice to make the monologues more interesting. The only catch is that it can affect the comprehension for those with hearing loss if not moderated well.

Nice news on the SSH updates. While there's no problem if both client and server run a modern version of openssh, it could be confusing to connect from modern to legacy system (e.g. an OpenWrt router which hasn't been sysupgraded for years), but all can be done with some knowledge and google-fu.

Fun fact. A week ago or so, I played a game called Scanner Sombre (awesome btw) which used a faulty OpenSSH feature code. Intel 10th+ generation CPUs apparently have a feature for better key generation and that faulty code caused the game to crash when attempting to use the CPU feature with it. Intel has posted an article about it "OpenSSL* SHA Crash Bug Requires Application Update." A game dev unrelated to this game has debugged the issue and made a tutorial to edit the executable to replace the OpenSSH commands by NOP and it fixed it. It was later found that just telling Windows not to use those features worked too, albeit not as fun. Perchance.

[@burcakb1]

[@nezu_cc]

The "More secure" part is debatable. Yes, you can get away with way smaller key sizes to achieve similar security, but they are fundamentally different algorithms. Comparing them isn't as simple as one might think. Whether it is more secure will depend on your threat model and key sizes. AFAIK rsa is still way more resistant against quantum attacks than Ed25519 for example.

[@VeronicaExplains]

I believe I said RSA is "often" less secure, and I said I'm not a cryptographer. But please, if you know of any reputable cryptographers who feel RSA public/private keys are a more secure choice than Ed25519, I'd like to hear it. :)

[@nezu_cc]

@@VeronicaExplains I mean we could argue about it, but realistically speaking both (at the current default key sizes) are more than good enough for 99.99% of use cases. Many bank and government websites to this day use RSA 2048 in their SSL certs. It all depends on the threat model, and let's be honest, if you're dealing with an organization that has the capability to brute force these algorithms, they also have the capability to raid your house/data center and just grab the server directly, and they won't bother with trying to brute force the algorithm unless they absolutely have to. More secure defaults, smaller keys, why not, but realistically speaking, it doesn't really matter, your old rsa keys are fine just fine.
