This is a (very wip) server-side implementation of the Oscar Protocol, used by AOL Instant Messenger and later versions of ICQ.

• Authentication Server
  • Only supports the newer authentication mechanism (TLV 0x4c) because I don't want to deal with plaintext passwords
  • Every username (no registration yet) can be used with the hardcoded password password

• Set AUTH_HOST env var (defaults to 0.0.0.0)
• Set AUTH_PORT env var (defaults to 5190)
• Run npm run build to compile
• Run npm start (or bin/aimserver)

This has only been tested with AIM for Windows version 5.2.3292, but theoretically should work with more clients.
