OSCAR stands for "Open System for Communication in Realtime", and while originally and ironically was not open, today it is. At one time used by AOL's AIM and ICQ products, and later discontinued, it now has had a rebirth of sorts here. We not only will fully document the protocol, but will maintain and update it.
If you want to contribute, you can request an account by sending an email to accounts@wiki.nina.bz with desired username and also a few words on what you have to contribute (for spam control).
If you want to contribute something anonymously or without registering, send it to contribute@wiki.nina.bz. If anonymity is desired, state so, and your name/email will not be mentioned.
Introduction
The OSCAR protocol is a binary protocol and is transmitted in network byte order unless otherwise noted. The application protocol stack consists of TCP for networking, a FLAP layer providing framing, and SNACs representing the OSCAR protocol messages. SNACs are broken into foodgroups (get it?) and subgroups which represent commands and services.
Many of the server connections support TLS between the FLAP and TCP layer if single hop encryption is desired. In most cases, the binary data stream is formed by appending the elements in order with no extra padding.
Sometimes within the ICQ community it's called "protocol v7/8/9" but this is inaccurate. Additionally the newer web-based API has been called ICQ v10 by a few. These version numbers are not accurate and typically come from the rendezvous/direct connection protocol version numbers.
Connecting
Depending on whether or not SSL/TLS is being used, and version of the protocol, different authentication servers may be used. The authentication server also acts as a load balancer and will return a BOSS server to connect to when authentication is successful.
| Hostname | Port | Protocol | Note |
|---|---|---|---|
| login.oscar.nina.bz | 5190 | OSCAR | OSCAR over FLAP |
| kdc.uas.nina.bz | 443 | OSCAR | OSCAR over TLS |
| api.screenname.nina.bz | 443 | OSCAR or WIM | HTTP-based clientLogin |
A single user can use multiple clients at the same time on the same or different devices. When building a client, or library, care should be taken to deal with a single user being online multiple times. In general, all IMs and Buddy notifications will be sent to all instances, although there are some IM routing rules that come into effect when users are away or idle.
Foodgroups
OSERVICE (0x0001)
The OSERVICE foodgroup contains basic operations and data types that are common across many of the foodgroups and even different servers. It is also used for service requests when the client needs to connect to a second server to perform some other action.
