Entries

Seemes to be 2 types of entries. Encrypted and Non - Encrypted.

Non-Encrypted files seem to be just png image files. Encrypted files seem to be just ESFM files, (encrypted container for trophy.sfm files)

Each ESFM file in the .trp file contain the same first 512 bits.

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 (stored inside system library) using AES-CBC-128. Then you can decrypt data using this key and IV from the header.

NP Com ID for above Buffer: NPWR05506_00
ESFM IV: 0x0 - 0x10
