===Part F: Cleartext certificates===
−This part is not encrypted. The exact details of this field is not yet analyzed, but it is likely related to the chain of certificates as described on the [[Tmd_file_structure|TMD file format]] page.
+This part is not encrypted. This data is an ecc signature, generated by the wii at content.bin creation time. Attached to the signature, is the ecc public key to verify the signature, and a certificate signed by nintendo's private key, to assure that we didn't just make up the ecc key ourselves.
