#ls2 (irc2p) | #ls2 I2P Protocol Development Discussion - Next Meeting Monday, October 9th 6:30 UTC

eyedeekay like I couldn't tell it a port to use or what host to listen on, so it would pick a random local one every time and so I'd have to get the port from the socket structure itself

eyedeekay that kind of thing bubbled to the surface

eyedeekay then I had to spend time over into some contexts that aren't part of this meeting

eyedeekay thulium's willingness to second-guess my refactoring decisions continues to be valuable, he's finding things to simplify about twice a week days and running them by me, right now he's looking at a refactor of the Certificate common interface and some of the things that implement it

eyedeekay looking forward to seeing what comes of that

eyedeekay we're both working on branches right now with merges planned for "Soon," optimistically we should start them this week

eyedeekay Other news: Progressing on godoc fixes, making more decisions on when and where it's appropriate/helpful to depend on a library vs writing something ourselves

eyedeekay EOT

zzz have you started work on ntcp2 data phase, or you just have the handshake so far?

eyedeekay Just the handshake so far still

eyedeekay No data yet

zzz yeah that was my guess. Still, sounds like good progress

eyedeekay I figure it will be hardest when it's new and this is all still pretty new to me

eyedeekay When I switch from Noise to NTCP hopefully I work much faster because I've already done it once

zzz thanks for the update

zzz anything else on 1) ?

eyedeekay you're welcome, nothing else on 1 from me

orignal sec

orignal are you able to recieve something back?

orignal e.g. with an existsing router

orignal your connect then send SessionRequest

eyedeekay Not with an existing router, that I've tried, yet

orignal do you receive SessionCreated back?

orignal what was the problem?

zzz I believe he's still working with an unmodified noise lib, he has to go back and do the aes-encrypt of the keys and add the padding

eyedeekay But again this is pure-noise and not NTCP2 so I'm not sure it should work at all, I've been talking to myself only for a while

zzz remember we advised him to start with unmodified noise first and then add the mods so he didn't get too messed up

orignal I would suggest to start with connection with somebody else

orignal and see how it should lokke like in reality

zzz sounds like he'll be there soon

orignal idk what "unmodifuied noice" mean

eyedeekay I'm sort of diving into the deepest of the deep end here, I've got no network engineering experience that didn't come from homelabs and I2P so I think I ended up taking some in-between steps to help understand things better

zzz unmodified noise == using a noise library unchanged (no AES encrypt of keys or added padding)

eyedeekay Trying to do an I2P SessionRequest over Noise without modifying it to behave as NTCP2 using the spec is what I've been trying to do in as specific terms as possible

orignal is there a noise library in go?

eyedeekay github.com/flynn/noise

orignal but noise itslef is veru simple

orignal just MixHash and MixKey

orignal two function

eyedeekay And I've also been using the Go noiseSocket implementation as examples

orignal that's all you need

zzz sure, but a library is a reasonable choice also.

zzz anything else on 1) ?

eyedeekay It's what all the examples I read are based on, and I'd rather use a lib than not for now

eyedeekay Maybe that changes someday

eyedeekay But nothing else for 1 now

zzz 2) ssu2 blog post update

zzz I've done a few edits

zzz added a mention of chacha2 for the headers

zzz added a performance section

zzz I now plan to finish by late next week, after our Oct. 4 monthly meeting

zzz because I want to have a decision on what we call the next release first

zzz EOT

zzz any more comments, let me know, thanks

zzz anything else on 2) ?

eyedeekay Just a sec I want to pull up the post here

zzz i2p-projekt.i2p/en/blog/post/2022/09/30/SSU2-Transport

zzz still working on fixing all the links

orignal what's your plan for the next release?

orignal regarding SSU2

zzz enable it for everybody

zzz that's been the plan for at least 6 months, no change

orignal please remning about the next release

zzz what about it?

orignal I will disable SSU and ennable SSU2 for everybody

zzz ok

orignal SSU2 looks stable for me now

orignal I have another question for eyedeekay

zzz oh yeah, speaking of stable, I did fix my short-packet bug

eyedeekay I don't think I have much to suggest in the way of phrasing/organization/etc, links are important for the sections where it's compared to QUIC but you mentioned tat

orignal when you try to use libi2pd in your go code, did it even work?

orignal because it seems a lot of missing initializations there

eyedeekay Yes it did work, but you have to construct the configuration and pass it in from Go, the example code in the go-i2pd repository should work

orignal did it connect with other routers?

eyedeekay Yeah I used it to build an application

eyedeekay It made a configuration directory, started a SAM bridge and everything

orignal because some guy pointed me that it kept crashing

orignal thanks

eyedeekay Hm. Well I don't know offhand why but I'll take a look at it this week and if there's anything I can do I'll fix it

eyedeekay Do you have a github issue for it? If not, could you have him file one on: github.com/eyedeekay/go-i2pd

zzz I don't think the 'some guy' was using your go code eyedeekay, I think it was a native C++ project?

orignal yes he uses C++ project

orignal but libi2pd

zzz anything else on 2) ?

orignal no

zzz 3) what is next

zzz your topic orignal, go ahead

orignal this is the qeustion

orignal I would suggest chacha20 encrytpion for tunnels

zzz maybe PQ

zzz maybe nothing for a few months

zzz other ideas?

orignal what is pq?

zzz post quantum

orignal and how is it related to us?

zzz maybe add it to ratchet, or ntcp2

orignal I don't understand what's an advantage

zzz maybe, maybe not

zzz zzz.i2p/topics/3294 for the discussion

orignal yes I read that topic

orignal but it looks nothing by hype for me

zzz you could start a thread on chacha20 tunnels, get the discussion started

eyedeekay I suppose whether one sees an advantage is based on whether one believes a CRCQ is imminent

eyedeekay a couple months would also give go-i2p a chance to catch up a bit

eyedeekay to what extent is human-readable addressing a common feature in the context of meetings we have here in #ls2?

eyedeekay *CRQC

zzz define human-readable addressing?

zzz define CRQC?

eyedeekay SusiDNS, addressbook, jump services, TLS potentially

orignal I see instance advatbnage of chacha20 vs. AES for 1K messages

eyedeekay Cryptographically-relevant quantum computer

orignal it's just faster

zzz sure, "human-readable addressing" is a valid topic

zzz anything else for 3) ?

zzz obviously we're not deciding anything today

eyedeekay OK. I didn't exactly come prepared for it, but I have some ideas about how our addressing might be improvable, in particular I'd like to define a protocol for allowing host providers to share addresses with eachother and under what circumstances they'll accept such a "sync" operation

zzz zzz.i2p threads always good to start discussion or "pre-proposals"

eyedeekay Don't have much for it written down but maybe I come to zzz.i2p with an idea soon

zzz interesting eyedeekay

zzz not clear if there's any middle ground between our current halfassed subscriptions and full-blown GNS

eyedeekay I had one of my toy projects, called "jump-transparency" which was designed to spot names that were registered with different keys on different services that sort of prototyped this but like a lot of things I did, it was an experiment that didn't get much attention after a certain point

orignal another thing

orignal possible disconnect Russia from Internet

orignal next month

zzz that would be something

orignal because on Sept 30 Putin will declare war

orignal to the world

orignal so i2p my split to two segments

orignal *mght

orignal just FYI

zzz you have any RU reseeds?

orignal R4SAS has one

zzz should we add it?

orignal I thought it's in the list already

dr|z3d we could probably get a reseed host up in kyiv, but that's probably not going to help.

zzz I have a reseed-pl and reseed-fr, but maybe that's a lie?

zzz "https://reseed-pl.i2pd.xyz/" + ',' + // r4sas-reseed_at_mail.i2p.crt // CA

zzz "https://reseed-fr.i2pd.xyz/" + ',' + // r4sas-reseed_at_mail.i2p.crt // CA

R4SAS no, it is not public

zzz ok, if you make it public let us know

zzz anything else for the meeting?

eyedeekay Nothing from me

zzz good luck R4SAS

zzz stay safe

R4SAS I will, but I need to think about reachability to my servers in RU )))

orignal ha ha

R4SAS would see in new month

zzz thanks everybody

orignal yes

orignal after 30-th

R4SAS i don't think they will block access for ex-USSR countries

R4SAS so there probably we will find possibility to get outside wall

dr|z3d Belarus will be fine.

orignal not they

orignal other world can do it

orignal Putin is too dumb to be able to do it

R4SAS don't underestimate the dumb
