HyperX Driver Coming For Linux 7.3 Just To Report A Microphone's Mute Status

A new driver coming for the Linux 7.3 kernel is HID-HyperX. It's not some new driver to support fancy hardware and some nifty features but rather mundane in nature due to the poor behavior of a high-end HyperX USB gaming microphone...

We haven't written up this one. Phoronix has the full story — the link below goes straight to it.

Ed25519 vs ECDSA: Why the Nonce Decides Everything

ECDSA and Ed25519 both sign data with elliptic curves, and both produce a 64-byte signature that verifies in a fraction of a millisecond.

  • ECDSA and Ed25519 use elliptic curves for data signing with 64-byte signatures.
  • Ed25519 automatically computes unique nonce, unlike ECDSA's random k per signature.
  • Sony's PS3 and Android's SecureRandom failures highlight nonce's critical role in ECDSA security.
