This is used by [[Home_Menu|Home Menu]] during TWL title-launch to pass a HMAC-SHA1 of the banner (size varies based on the banner version, etc.) to TWL_FIRM using the TWL and NTR SRL HMAC keys. This is presumably used for comparing against the HMAC stored in the [[Title_list#TWL_System_Titles|whitelist]] for titles without RSA. | |||
