  • Who are we? (exited SILC users)
  • Why SILC? (enc and auth traffic, new design -> advantages, why an irc-SSL layer isn't the way to do it...)
  • Short history of SILC
    • How it begun
    • Status of the project
  • Technical intro to the protocol
    • based on the white paper
    • A few things that are designed better compared to IRC
      • Nicks/Clients
        • SILC: not unique, unique Client ID; identicated by public key (no nick services needed); attributes and present modes
        • IRC: unique; authenticated by password/host mask (nick services needed); userinfo through service, away only
      • Channels
        • SILC: unique; founder mode (no channel services needed); channel public keys possible
        • IRC: unique; channel services needed for registration;
      • Messages/File transfer
        • SILC: all messages encrypted; all messages pass server; messages can be sign; multimedia messages possible; SFTP mandatory, other file transfer protocols possible
        • IRC: all messages are unencrypted, ctcp/dcc for e2e communication and file transfer
    • How it works using the silc-client
      • Show a few things:
        • Chat (found channel, what is founder, founder mode, save your key!)
        • nicks (double nicks)
        • MIME message to the channel, ...
        • signed messages
        • private channel key
        • client auth channel
        • private msg key (pubkey, passphrase)
        • watch
        • detatch
    • Other clients
    • How to setup silcd (if there is still time, we got 45 min)
      • Go over the config file
    • Links
    • (known bugs)
