Note: I'm not subscribed to this list, please use "reply-all" to make sure I get Cc'd on your reply. Hello! I have recently announced some upcoming changes to my Gemini software implementations with respect to TLS and TOFU: https://lists.sr.ht/~sircmpwn/gmni-discuss/%3CC9OP7IK9T9EP.15EOEOOS7QSB9%40taiga%3E I've also updated my older TOFU recommendations article to reflect the changes: gemini://drewdevault.com/2020/09/21/Gemini-TOFU.gmi In short, after listening to some feedback from the community on TOFU, I'd like to make the following updated suggestions: - Use long-lived certificates with the expiration set to the far future - Client software should disregard notBefore/notAfter dates, and the common name as well. Requiring strong algorithms and other technical constraints is fine. Any server software which wants to migrate to long-lived certificates should let their current certificates expire and then automatically issue a long-lived certificate to replace it when the time comes, rather than switching immediately and causing your clients to flag your cert as untrusted. To re-state one of my previous recommendations, which I still figure is a good idea: server software should handle certificate maintenance for the user. Making the sysadmin generate certificates is cumbersome and error prone, and because Gemini encourages TOFU and self-signed certificates, we can remove that burden from server operators entirely by generating certificates on-demand for the hosts we intend to service. Aside: it might be a good idea to have a non-authoratitive TLS best-practices document on gemini.circumlunar.space somewhere. I'd be happy to draft up such a document if this is desirable.

Installing extra software, running an HTTP server (or TLS-ALPN) for LE to query, running a cronjob (and keeping it running!)... there are a dozen places for error here and it requires a lot of manual setup. Just because you already did the work doesn't mean that it's easier! In Gemini, we have the privilege of skipping all of this entirely and having zero-configuration TLS. The server generates a certificate and it just works. This is much easier.

I'm glad you noticed it :) In response to the way you put it, "Someone not wanting to be part of a group, yet speaking to that group, might not be deserving the courtesy of a response that ventures outside the confines of that group." Or something to that affect. I think you get my implication there. IOW, why would I show someone a courtesy they refuse to extend to me? Good catch there Ben :) -- Bradley D.

And each and every client understand it differently ? if at all. To add insult to injury, it's purely optional. Optional! While TLS is mandatory! It's fantastic that servers generates certificates on the fly ? trivial things first. But then what? What's the operating model? Specifically. Consistently. Across the board. If each client-server pairs have their own view on how to handle TLS ? then Gemini has nothing at all. Just a giant mess. With mandatory TLS pain for everyone. I don't get it. So be it. ?0?

Not sure where the disconnect is. Oh well... ?0?

The mailto link in the list archives (see the "From" header) includes an in-reply-to header which is able to handle threading. But it's pretty annoying to use this, which is why I asked to be Cc'd. > Trying out gmnisrv just yesterday, I was quite happy that it generated > the cert files for me. Cheers :)
I don't know what to tell you two. There are zero steps with using an auto-configured self-signed certificate. It requires no ongoing maintenance. There are 5 or 6 steps involved in using Let's Encrypt, and you have to top it up every 80 days. You're simply wrong. It's not easier, and that's a fact.

No, I asked for a simple courtesey which is common on mailing lists everywhere. It should be quite plain to any observer of this thread why I felt it appropriate to bemoan this mailing list on IRC. Take a look in the mirror, bud. This thread demonstrates quite neatly why I'm not subscribed to the mailing list in the first place: because it's full of such esteemed posters as yourself.

I don't mean to derail the focus of the conversation which is TOFU and TLS, but as a newbie to this mailing list, I have to agree with the quoted sentiment above. It seems there's a bit of vitriol to an "outsider" (Drew introduced me to gemini through his blog) who is trying to share his recommendations. I see nothing wrong with a non-subscriber sending an email to the list. It's easy to archive/trash/filter out the sender if you don't want to acknowledge their existence.

Honest answer for me. I'm subscribed to this list. But I did read it from the webarchive for quite some time. I had been subscribed to some high volume lists times ago. BUT I can't cope with that, so I consult the web archive of such lists and chime in if I need it. It is a matter of being nice to include someone, who asks for being CC:ed.

I usually refrain from getting involved in ML discussions. The reason is that I often don't have anything useful or good enough to contribute, and also I am aware the ML is very high-traffic and the last thing we need is more discussion. I have been on this mailing list for a long time, before it was ever this crowded or active. I remember getting just one message from in the span of a month, maybe longer. I'm not a big fan of moderation or exclusion. The first time I saw a message on the mailing list that I genuinely felt was bad and shouldn't have been sent (because it was too rude/direspectful or obnoxious), it was from Petite Abeille. I did not say anything, but it felt out of character for this list and this community. But hey, we are patient and tolerant, we can learn to get along, right? Petite Abeille, if you are genuinely interested in Gemini and wants to be part of the community, I would not like to see you banned. However, I would implore you to reconsider how you interact on the ML. I can't help but feel you played some part in people being driven out of the ML, though of course not the only part. As an additional matter to consider, in case some members of the mailing list are not aware (although most probably are), Petite Abeille is not a person's name, but it means "little bee" in French. I got the impression this name was chosen deliberately for trolling, to be anonymous and convey the message that this is a disruptive creature buzzing around and poking us with its stinger. Also, some people might not be aware, but this mailing list was not supposed to allow Gmail addresses, but a special exception was made for people interested in Gemini to be allowed to use it. It was thought this is for the benefit of the community. However, perhaps we've also unwittingly opened up the list to abuse by throw-away e-mail accounts? Just some things to consider.

Drew, I know you to be an otherwise upstanding person who prides himself in his capacity to provide service to the community for a greater good. But I stated what I stated, and that is not what I stated. Please do not put words in my mouth - especially since I never said, *easier*. I never implied that it was not also easy to use self-signed certs (and most servers I'm aware of will perform this automatically if you don't provide a certificate yourself). What I said is that it is easy (rather, Easy Peasy, I think) to use LetsEncrypt to handle all of that automatically. Trying to imply that I said something I NEVER said, which implies that I meant something else, is beneath you. Please refrain from such behavior in the future where it concerns me - a single, individual person. I'm not angry with you, I'll just chalk this up to you losing context because you are as passionate about Gemini space as many of us others are that have been involved with the project since the very beginning. I don't recall seeing any participation from you prior to about six months ago. Again, that's okay, and I think your intentions are grand - don't put words in my mouth though.

Mailing lists are a multiplayer venue. This thread has two people, yourself one of them, who have expressed that Let's Encrypt is easy. You are not the person who said it was "easier" (emphasis on the "er"), and the person I directly replied to in the thread with my comments was someone who did.

It's evident that you only have half of the conversation, which is not my fault. I will note that you still refuse the basic courtesy of Cc'ing me on your replies. Not sure what moral high ground you seem to perceive yourself as coming from here.

Wow, Three years of French at UCSD and I didn't make that connection. I filtered that user a long time ago when it became apparent that I didn't find anything constructive coming from the account, for me personally. I typically do that with serial Top-Posters too, I find that even more annoying and detest having to continually scroll up/down/up/down just to figure out what's being conveyed. > > Also, some people might not be aware, but this mailing list was not > supposed to allow Gmail addresses, but a special exception was made for > people interested in Gemini to be allowed to use it.

I still block them from purchasing many services from me - Google is the great facilitator of legitimized Spam. Sean's deployment of tracking issues via Gitlab was a great idea to avoid noise while working, and effectively creates a WG (working group) that can focus on the matters at hand. Personally, I would have probably chosen tildegit, since many of the major contributors are homed in that community, or perhaps Codeberg, or even sr.ht (Yeah pls don't flame me for that - it's a good service), but Gitlab works and isn't GitHub so that's good.

The only issue with tildegit is that it's restricted to people that are in tildes. You can request an account (real people are the ones validating requests after all) but many people wouldn't want to sign up for a new service just to work on the Gemini spec. For instance, I don't have a gitlab account and therefore am not participating in those discussions because why would I make a whole new account for literally one thing. I do have a tildegit account which would make it better for me, but then you'd be putting lots of other people in my situation and cutting a lot of valuable contributors out. And yeah, github is a no-go for obvious reasons. I would vote for sourcehut because you don't need a sourcehut account to participate (same with this ML), while still keeping the discussion separate from this list, which, IMO, should be announcements of interesting software and new capsules and things like that, plus formal spec announcements. Oh yeah, learning to block users in your email server or email client is a valuable skill, particularly on this list unfortunately. ~nytpu -- Alex // nytpu alex at nytpu.com GPG Key: https://www.nytpu.com/files/pubkey.asc Key fingerprint: 43A5 890C EE85 EA1F 8C88 9492 ECCD C07B 337B 8F5B https://useplaintext.email/ -------------- next part -------------- A non-text attachment was scrubbed...

Yes, the party to which you refer is an account that I filtered to /dev/null a long time ago. My bad. It appeared as if you were referring to me. You'll note I also cc'd you on this. It's my practice to set my MUAs to only "reply list", since that's where I'm conversing. I can't promise anything in the future, but I'll try, and a friendly reminder with each of your posts will help :) On another note, I would appreciate it if you would take a moment to ensure that your webproxy agent stays off my lawn at *.vger.cloud. I have no qualms about other types of agents, I just personally believe that people should use native Gemini and Gopher protocol clients (which includes browser plugins such as dillo-gemini, qute-gemini, OverbiteNX, and SSH kiosks) to browse Gemini and Gopher space.

My proxy's IP address is 173.195.146.137, I leave the rest up to you. It's my proxy's responsibility to dutifully perform the requests the user asks of it, and it's your responsibility to curtail whatever kinds of traffic you don't want to access your server. I do not support discrimination against user agents, because that's discrimination against users.* For what it's worth, my proxy only serves my domain and serves external content only if the user follows links from my domain to a third party. It's not useful as a general purpose web portal to geminispace.

A trollish name could be "little wasp". Bees are industrious and useful insects (honey, pollination). The wasp sting is also more frequent and more painful than bee sting. ...so, "Petite Abeille" sounds more positive to me :-)

That said, I still don't get the TOFU usage model in the context of Gemini... not that I necessarily need to understand it to have a good night sleep, but still... out of curiosity... In ssh, I know the host, therefore I trust the key. Plus, this happens only every blue moon. No brainer. Not so in the wild-wild Gemini space. Infinite number of esoteric, fly-by-night operators. All harmless for sure, but still. What's the trust model, if any? Or is it more like Trust-And-Pray (TAP)? In which case, why bother? Just ignore all certificates and be merry. This is what a Little Bee impersonator had to say on GitLab: Trust on first use (TOFU) is akin to unprotected intercourse: you must trust your partner to keep Gonorrhea at bay. No trust, no use. https://gitlab.com/gemini-specification/protocol/-/issues/5#note_522445814 It was not well received, needless to say. That much is clear. ?0?

If for whatever reason you need to renew a certificate (e.g. to use stronger encryption) you can just swap it out.

Without a chain of trust, and ignoring notBefore/notAfter, there's no point in waiting. The client (according to the procedure you describe in your article) will find the old cert in known_hosts in step 2., see that the served certificate differs and consider the new certificate UNTRUSTED. That is true regardless of whether you immediately replace the certificate or wait until the old one has expired, unless the client *doen't* ignore notBefore/notAfter and uses those dates to vacuum known_hosts to remove expired certificates automatically (which is impossible given the store format you currently recommend). The procedure you describe does not provide for any other way to roll out new certificates than for the new one to be UNTRUSTED, nor do I think clients are able to provide this in general outside the use of certificate authorities or validity date based vacuuming of known_hosts. That's really how it has to be for TOFU: whenever a new certificate is used, a new trust has to be established. *Any* certificate that you haven't used is untrusted. IMO, UNKNOWN is really the same thing as UNTRUSTED. There is no UNKNOWN state; either I've asserted my trust in the certificate or I haven't. UNKNOWN and UNTRUSTED are just different cases of untrusted certificates, with latter giving you an additional piece of information: that you have already trusted a different certificate for the given host. I think it's better for clients if they are treated as such. In my client, the user gets a choice whenever they encounter a new certificate. If the trust store happens to contain a different certificate for the host, that information will be displayed to the user as well, so that they can use it as a basis for the decision whether to trust the new certificate. Manually editing known_hosts is just that, "with extra steps". > To re-state one of my previous recommendations, which I still figure is > a good idea: server software should handle certificate maintenance for > the user.

"Warning fatigue has pushed many messaging applications to remove blocking warnings to prevent users from reverting to less secure applications that do not feature end-to-end encryption in the first place." https://en.wikipedia.org/wiki/Trust_on_first_use#Model_strengths_and_weaknesses https://en.wikipedia.org/wiki/Alarm_fatigue This doesn't scale. Could as well accept everything. Or ignore everything. Same effect. ?0?

The format I previously recommended stored the expiration date, and other clients might as well. Waiting to rotate is the most conservative choice which maximizes your compatibility with the most clients regardless of their adherence to these best practices. > Agreed.

I think your criticism only applies in a transitive sense, while the community is moving from one procedure to another, and should have little influence on any kind of proposed standard or guidelines.

I appreciate what was constructive about your response, but this last part presents a practical problem. When I wrote to you I asked you to make a sincere effort to take the mailing list more seriously. "feel free to ban me" comes across as a negative response.

Not storing the port means that the client can't adequately support different certs being served on different ports. You can test with: wikipedia.geminet.org wikipedia.geminet.org:1966 2. Not storing the expiration timestamp means that the client can't issue a less scary warning when it receives a new cert after the old one expired (or when it's about to expire). Solderpunk argued in favor of clients using expiration dates, for ex: gemini://gemi.dev/gemini-mailing-list/messages/002101.gmi > I guess I see the main utility of explicit expiration dates in this > context as being a kind of promise from the sever admin that "I have no > plans to do a key rotation for about this length of time". This means > that apparent MITM attacks happening at a time when there's a lot of > validity left can be treated with much higher suspicion. 3. A cert can be renewed without changing its public key, so storing a hash of the SPKI (SubjectPublicKeyInfo) instead of the entire certificate means potentially less unnecessary warning messages for users. Here's the OpenSSL command to extract the SHA512 hash of the DER-encoded SPKI: openssl x509 -pubkey -noout | openssl pkey -pubin -outform der | openssl dgst -sha512 -binary | openssl enc -base64 -A I used base64 at the end to get a shorter string. And here's the command one would use to renew a cert without changing keys: openssl req -new -x509 -key private_key.pem -out new_cert.pem -subj "/CN=example.com" -days 36500 It generates a certificate valid for 100 years using the old key. Amfora uses the SPKI, so it wouldn't raise a warning about this new cert.
