is someone able to help me to validate this Caps Hash? ``` <query xmlns="http://jabber.org/protocol/disco#info" node="http://gajim.org#KV4qaXUgvEqhWE7WEJoqvO6gTYA="> <identity type="pc" category="client" name="Gajim" /> <feature var="http://jabber.org/protocol/bytestreams" /> <feature var="http://jabber.org/protocol/si" /> <feature var="http://jabber.org/protocol/si/profile/file-transfer" /> <feature var="http://jabber.org/protocol/muc" /> <feature var="http://jabber.org/protocol/muc#user" /> <feature var="http://jabber.org/protocol/muc#admin" /> <feature var="http://jabber.org/protocol/muc#owner" /> <feature var="http://jabber.org/protocol/muc#roomconfig" /> <feature var="http://jabber.org/protocol/commands" /> <feature var="http://jabber.org/protocol/disco#info" /> <feature var="ipv6" /> <feature var="jabber:iq:gateway" /> <feature var="jabber:iq:last" /> <feature var="jabber:iq:privacy" /> <feature var="jabber:iq:private" /> <feature var="jabber:iq:register" /> <feature var="jabber:iq:version" /> <feature var="jabber:x:data" /> <feature var="jabber:x:encrypted" /> <feature var="msglog" /> <feature var="sslc2s" /> <feature var="stringprep" /> <feature var="urn:xmpp:ping" /> <feature var="urn:xmpp:time" /> <feature var="urn:xmpp:ssn" /> <feature var="http://jabber.org/protocol/mood" /> <feature var="http://jabber.org/protocol/activity" /> <feature var="http://jabber.org/protocol/nick" /> <feature var="http://jabber.org/protocol/rosterx" /> <feature var="urn:xmpp:sec-label:0" /> <feature var="urn:xmpp:hashes:2" /> <feature var="urn:xmpp:hash-function-text-names:md5" /> <feature var="urn:xmpp:hash-function-text-names:sha-1" /> <feature var="urn:xmpp:hash-function-text-names:sha-256" /> <feature var="urn:xmpp:hash-function-text-names:sha-512" /> <feature var="jabber:x:conference" /> <feature var="urn:xmpp:message-correct:0" /> <feature var="urn:xmpp:eme:0" /> <feature var="urn:xmpp:avatar:metadata+notify" /> <feature var="http://jabber.org/protocol/mood+notify" /> <feature var="http://jabber.org/protocol/activity+notify" /> <feature var="http://jabber.org/protocol/tune+notify" /> <feature var="http://jabber.org/protocol/nick+notify" /> <feature var="http://jabber.org/protocol/geoloc+notify" /> <feature var="http://jabber.org/protocol/chatstates" /> <feature var="http://jabber.org/protocol/xhtml-im" /> <feature var="urn:xmpp:receipts" /> <feature var="urn:xmpp:jingle:1" /> <feature var="urn:xmpp:jingle:apps:file-transfer:5" /> <feature var="urn:xmpp:jingle:security:xtls:0" /> <feature var="urn:xmpp:jingle:transports:s5b:1" /> <feature var="urn:xmpp:jingle:transports:ibb:1" /> <feature var="eu.siacs.conversations.axolotl.devicelist+notify" /> </query> ```

Woah

my code always tells mt its wrong, I don't see why, have not seen caps hash errors in years ;-)

Prosodys util for this says `KV4qaXUgvEqhWE7WEJoqvO6gTYA=`

can you paste this somewhere?

Code block rendering that doesn't take up the entire screen would be nice. *hint* client authors :)

jonas’‎, you need a bigger screen ;-)

Zash‎, so Prosody sais its correct? Then something is getting messed up in my codes 🤔

Yes

https://xmpp.org/extensions/xep-0115.html#ver-gen-complex

can you point me ot the Prosody code you used to verify? Then I can debug and try to find dthe issue

https://hg.prosody.im/trunk/file/tip/util/caps.lua

have tons of samples in my unit tests which all succeed, but it does not like that one for some reason :(

thanis

how do I execute this LUA util?

Lua*

Save this as caps.lua or something: `print((require "util.caps".calculate_hash(require "util.xml".parse(io.read("*a")))))`

assumes it's in a prosody checkout and you built the C stuff and have all the dependencies

are you able to send me the string which LUA concats before building the hash?

https://www.lua.org/about.html#name

Lua*

It's the second return value of calculate_hash()

looooooooong line at the end

thank you, owe you a beer next time we meet ;-)

Alex this is a very easy example

so i guess the only thing that can go wrong with that is preparing the identity correctly

so i would look into that

first

this is where I looked forst and thought its related to the xml-lang which Gajim put on the iq, but this looks correct

if you find the problem i also would be interested to know in which trap you fell

Looks like its this: ``` urn:xmpp:hash-function-text-names:md5< urn:xmpp:hash-function-text-names:sha-1< urn:xmpp:hash-function-text-names:sha-256< urn:xmpp:hash-function-text-names:sha-512< urn:xmpp:hashes:2< ``` vs ``` urn:xmpp:hashes:2< urn:xmpp:hash-function-text-names:md5< urn:xmpp:hash-function-text-names:sha-1< urn:xmpp:hash-function-text-names:sha-256< urn:xmpp:hash-function-text-names:sha-512< ``` some weird stuff going on in .NET string sorting which I am hitting for the first time

the i;octet collation is relevant for sorting

ya, it looks like .NET by default sorts by OS culture, fixed by using `StringComparer.Ordinal`

this code is on prod for over 10 years and hitting it the first time 😀

I sure hope nobody goes and invents some non-ascii feature

my OS is using Germany culture settings

time for a walk before publishing a fix, Thank you guys for the help 👍

hi everyone, currently im having trouble with implementation stanzas on xmpp.js. can anyone help me about it?

sonny, ^ ?

Feel free to open an issue with your question on the repository and I'll have a look

okay thanks i ll move on there
