Formatting HDCP Keys for HDCP 2.3 - 3.1 English - PG236

The hdcp_key_utllity.c has two (empty) HDCP 2.3 key arrays.

• The hdcp22_lc128 array

  The global secret constant for the HDCP 2.3 TX. The size is 16 bytes and the license constant from the HDCP 2.3 TX certificate is placed into the array (position 4-19).

• The Hdcp22RxPrivateKey array

  This array holds the HDCP 2.3 RX certificate. The array has a size of 902 bytes. The contents are the header (4), license constant (36 bytes) and key set (862), so the total is 902 bytes.

  Note: If a pass-through example design is built which contains an HDMI RX component, you can use the same hdcp_key_utility application to program the HDCP 2.3 RX Private Key.
