Reverse Engineering Supermicro IPMI (2018)

  Why is the private key saved on the rom?
  • duskwuff 5y ago
    Because that's the only key. HMAC isn't a private-key algorithm.
    • marshray 5y ago
      I think you meant to say HMAC isn't a public key algorithm.
      • richardwhiuk 5y ago
        It's a symmetric key algorithm not a public/private key algorithm.

  The Supermicro Redfish API is unlocked with the same key, at least that was the case the last time I experimented with it back in 2019. You can use Redfish, in theory, for bare-metal management of servers. I never went all the way with it, so I don't know how solid the implementation is.

  Alternatively you can probably download a free copy of FreeDOS and use that to install the update.

    Does FreeDOS boot off a flash drive?
    • 1MachineElf 5y ago
      Yes, it does. Booting a FreeDOS flash drive is how I update Supermicro BIOS and flash HBAs with IT mode firmware.

      It is possible to boot DOS from USB flash using systlinux.
