Structure

Note: This isn't complete.

typedef unsigned char u8;
typedef unsigned long int u32;
typedef unsigned long long int u64;

typedef struct{
	u32 magic; //Ü¢M.
	u32 version; //#3 on ps4
	u64 fileSize; //size of full trp file
	u32 entryCount; //num entries
	u32 entrySize; // size of entry
	u32 unk1; //padding probably
	u8 hash[20]; //sha1 hash
	u32 unk2; // 0x30313000 ??
	u8 padding[0x2C];
} header_t

typedef struct{
	signed char name[0x20];
	u64 entryStart; //relative to &buffer
	u64 entryLength;
	u32 unk1; //3 on some, 0 on others, could be flags or an enum to determine if encrypted or not?
	u8 unk2[0xC];
} entry_t;

Entries

So far (from what I've seen) there are only 2 types of entries.

ESFM which are encrypted, and PNG which are not encrypted.

PNG is plain image data

ESFM is encrypted but seems to contain the same bytes at the top.

ESFM is just an encrypted XML format. It consists of IV of 0x10 bytes and the data itself. A key is generated by encrypting NP communication ID with keygen ERK/keygen IV using AES-CBC-128. Then you can decrypt data using this key and IV from the header.

ESFM IV: 0x0 - 0x10 ? KeyGen ERK: 0x10 - 0x30 ? KeyGen IV: 0x30 - 0x40 ?

That's all so far ~Jakes625
