Int. Silkroad CREST system revealed

Well we have revealed in it night - I have to express my thanks to Callum for borrowing me iSRO account and Rafa for packet and listening to me on MSN: "Thanks you very much!"

Basics

• ISRO does not use FTP, they use plain HTTP server for crest storing
• ISRO crest server does not have +Indexes (enabled directory listing), so you will always get, to following lovley message when trying to list crests. Wicked, is not it?

  디렉터리 나열이 거부되었습니다.
  이 가상 디렉터리에서는 콘텐트를 나열할 수 없습니다.

  In English (translated by great Google Translator) it says:

  Directory listing denied.
  This virtual directory can list the content.

• ISRO crest naming convention is same as in Chinese/Korean version
  

Packets
We (they, since I am not working directly on server emulator) had some unknown data in one of their packets. Here comes described data part of packet.

Size    Type            Name            Description
---------------------------------------------------
1       char            flag            ?
4       long            guildId         ID of guild
varies  scstr           guildName       Name of guild
4       long            crestIndex      Index of crest

Example with some actual data (packet was caught on Uranus server).

Name                    Value
---------------------------------------------------
flag                    01
guildId                 71 0B 00 00
guildName               0B 00 44 69 76 69 6E 65 45 6C 69 74 65
crestIndex              03 00 00 00 

Getting crest
Now, that we know structure of packet, we can assume how client gets crest from its (crest) server - no matter, whether it uses FTP or HTTP based storage.

However I have described structure of crest name in my Silkroad CREST project post, I will write it here again.

Name                    Description
---------------------------------------------------
type                    Type of crest (Aliance, Guild)
serverId                ID of server
guildId                 ID of guild
crestIndex              Index of crest

Knowing this, we will rebuild name of this actual guild's crest (using data from packet example and knowledge of Uranus server I).

Name                    Value
---------------------------------------------------
type                    G
serverId                187
guildId                 2929
crestIndex              3

Which takes us to name G187_2929_3.crb - easy, is not it?
Now, if we want (of course we want) to download this crest from ISRO, we have to use following url.

As bonus, I give you list of servers with their IDs.
