Talk:Spkg hdr.tar

On 3.55 all .spkg_hdr.1 files are not involved in updating, I think that on 3.56 all of them are used as in overlayfs: so all .spkg_hdr.1 files are readed as metadata headers of same pkg files, decrypted by newer spkg keyset to get the same SCE file keys to get rest of .pkg files data decrypted.

UPL.xml.pkg is decrypted using pkg keyset [0x0000 03.55], UPL.xml.pkg.spkg_hdr.1 is decrypted using spkg keyset for > 3.55: only Metadata Info changes.
