User Token[edit]

  • Before User Token Manager encrypts a received user token it checks it's format.
  • User Tokens are processed by spu_utoken_processor.self
  • Before User Token is processed, User Token Manager reads IDPS by sending SS requests to Indi Info Manager (packet ids 0x17001 and 0x17002). Indi Info Manager runs in HV Process 5.
