AM module uses [[Application_Manager_Services_PXI|AMPXI:DecryptDSiWareData]] for decrypting each DSiWare section. After decrypting a section via that command, AM module calculates a hash over the decrypted payload data for [[AMPXI:ValidateDSiWareSectionMAC]]. The footer hash for this section is then verified by calculating a hash over the cleartext data as well.

After AM module validates the header, AM module then uses [[AMPXI:ValidateDSiWareMovableSedHash]]. The footer ECDSA verification is handled by [[AMPXI:VerifyDSiWareFooter]]. The decrypted banner is written to inputbuffer+0.
