The ps5-pup-decrypt tool is a utility designed to decrypt PlayStation 5 (PS5) firmware update files, known as PUP files.
Developed by zecoxao, this tool leverages the PS5’s own capabilities to decrypt these files, which are typically encrypted by Sony. The decryption process is crucial for developers and enthusiasts who wish to explore or modify the firmware.
The development of ps5-pup-decrypt involved contributions from several individuals and groups:
To use ps5-pup-decrypt, follow these steps:
safe.PS5UPDATE.PUP
.PS5UPDATE1.PUP.dec
and/or PS5UPDATE2.PUP.dec
.make
to compile the tool.The tool only works with PUP files that are either:
It does not decrypt certain files like system
, system_ex
, and wlan
.
Once decrypted, the PUP files can be unpacked using the ps5-pup-unpacker tool, which is also available from zecoxao.
This unpacker can extract the contents of the decrypted PUP files into individual files, although it does not handle nested filesystems.
ps5-pup-decrypt is a valuable tool for those interested in exploring or modifying PS5 firmware.
By leveraging the PS5’s own decryption capabilities, it provides a way to access the contents of firmware updates, which can be further analyzed or modified using additional tools like the ps5-pup-unpacker.
