Firmware Packages
File Header
All values are in big endian format.
typedef struct { u32 0x00, 0x53434500// magic u32 0x04, 2 // version u16 0x08, 0 // sdk type? u16 0x0a, 3 // SCE header type; pkg u32 0x0c, 0 // meta offset u64 0x10, // size of sce_hdr + sizeof meta_hdr u64 0x18, 0x80 // + content_size_real }
Game Packages
All game packages are signed with the ECDSA signature. The public key for it can be found in download_plugin.prx or in nas_plugin.prx (this also applies to NPDRM SELFs). Usually game packages are signed with two signatures - one for the header and the other for the entry table.
File Header
All values are in big endian format.
typedef struct { u32 magic; u32 pkg_type; u32 pkg_info_offset; u32 pkg_info_size; u32 header_size; u32 item_count; u64 total_size; u64 data_offset; u64 data_size; char contentid[0x30]; u8 digest[0x10]; u8 k_licensee[0x10]; } PKG_HEADER;
