OK, I will ask the other way? How would you trust I am me? (or how 
to write it in english), if not to trust some third party = CA? IIRC 
Carl or Josh said, that new SDK (dunno if it was ment generally, 
or only for plug-in), could generate some special license key or 
certificate for me, so that users could check? Similar aproach as 
when you install driver and you have the ability to check, if it 
comes from trusted party. That was all my point why I asked if it 
is coming.

plug in - that's ActiveX signing. it's a MS thing mainly.

rebol side - just use rsa signature as shown in rebol.com docs. ie 
just add signature to your rebol script

then i only need to know your public key.

since i need to be sure that the public key i have i yours, and not 
someone else, we need a trusted party - that's called a CA

ie someone that certifies that you are actually Petr and not an impostor

Gabriele - probably so, because IIRC guys pointed me to be able to 
parse ... uhm, don't remember what it was ...

that can be done 100% in rebol. if you need to interoperate with 
other systems, then you need to parse their formats, eg x509.

but... it's just parsing. it would be nice to have built in... but 
i don't see it as show stopper.

I know - but do you think ppl will trust some home made CA? I thought 
that I will come to one of three CAs here, and will ask for commercial 
certificate (dunno who does so internationally - Thawte? Verison?)

Verisign etc. But it depends on the app.

in general, yes, you have to support the big guys like Verisign... 
but that really depends on the app itself.

eg. if we're talking about the employees in your company, your company 
could be your CA, since you already trust your own company to some 
degree

There is no other level, as how to build "trust" amongst ppl in open 
environment.

i can only say, that i haven't encountered the need to parse x509 
so far.

otherwise... i would have solved the problem in some way... it's 
just parsing. worst case you call out to some known good parser like 
openssl

and if you don't even want to trust rebol's internal rsa code... 
you can call openssl for everything. that code is trusted by all

Yes, I know. But imagine me being an evil man. I will register with 
RT. They have their own CA, register me, give me certificate. I will 
do evil script. PPL will trust me, run the script, and damage will 
come. They turn to RT, and RT tells them - that developer is Petr 
Krenzelok. And I say - what? I never registered. So, the only way 
of RT to know I am who I am is, that I will visit some CA, provide 
some evidence (ID card, driving license, passport), and register, 
no?

that's correct, RT should never certify you are you without having 
proof.

What I am talking all the time about is - how to build trust in distributed 
environment. Some of us will need to produce scripts with lowered 
security. If I see a requestor asking me for lowering security, I 
will not run the app, unless I can be sure, that it comes from Gabriele 
for e.g., and that if Gabriele ruins my HD data, I can visit DevCon 
next year and ask for refundation :-))

a digital certificate is just like a paper certificate - the value 
depends on the issuers, and the parties involved.

someone may trust a document signed by me, someone else will need 
an official document from some state authority.

trust is generally based on chains

i trust you because someone else i already trust trustes you.

in order to be able to verify certificate, you need to verify it 
against the root certificate of CA. So if RT becomes CA for its developers, 
it would be better for them to be able to verify, who asks for certificate. 
E.g. visit devcon in private, for Carl to be sure who you are :-)

basically, since you are running rebol.exe, you are trusting rt already.

yes, rebol.exe could do damage in the extent of my OS user priviledges.

so, if rt can identify me (eg in person at devcon like you say) and 
tell you via certificate that a script is really from me (identification 
+ authentication), you can then trust the script if you trust me

hmm, host executable is open sourced, right? Who will be officila 
provider of such exe?

yes

who's the official provider of linux? :)

rt will provide an official one

but easier for RT to verify you is to accept some certificate, than 
to travel to devcon :-)

ah, linux ... so true .... you have to take some risk ....

Simply if I find some R3 distro with modified host environment, so 
better I am sure where it comes from, right?

what i mean is, the tech side of things is in rebol. the non-tech 
side is a different matter altogether.

right :)

same thing if you find any exe anywhere.

if someone sends you rebhost.exe via email... well... i would not 
run that ;)

that is why I think we should think about signatures (which is just 
a hash) and certificates in a bigger picture - mainly when we think 
about SDK apps or browser plug-in apps with lowered security level 
... the truth is, it does not need to come with initial release, 
but should not be forgotten about.

looks like R3 with 1000 animated gobs on 1000x700 window is at least 
2x faster than R2 with 1000 animated faces on 1000x700 window. (someone 
has reported 5x)

wow, this will be good :-)

guys, any other spoiler for us unlucky? :-)

what about porting Particles demo for e.g.? Or any other clever measurement 
gui stuff?

there was some simple script measuring FPS (refresh rate), it would 
be curious to see how AGG compositing helped us.

I'm gobsmacked ! :)

what does it mean? :-)

ah, gob, so some relation to gobs?

that probably mean at least one thing - you are part of early testing 
group. So, now off to private chat and prepare for being investigated 
:-)
