MASTER_PSK [1/2]

const uint8_t MASTER_PSK[32]

Initial value:

= {
  0xA1, 0x3C, 0x7F, 0x04, 0xE8, 0x92, 0x5B, 0xD6,
  0x3A, 0xFF, 0x01, 0x88, 0x4D, 0x62, 0xC0, 0x19,
  0x77, 0x2E, 0xB3, 0x55, 0x0C, 0xAD, 0xF1, 0x39,
  0x6B, 0x84, 0xE0, 0x27, 0x93, 0x5A, 0x1D, 0xCC
}

256-bit (32-byte) Pre-Shared Master Key for ChaCha20-Poly1305 AEAD.

Both nodes must carry the IDENTICAL key compiled into their firmware. Replace placeholder bytes with your own secret values before deploying to hardware. The key is NEVER transmitted over the wire and must NEVER be logged to Serial, LCD, or any other output channel.
