PS3Dec is a remake of the original PS3 decryptor which decrypts PS3s redump ISOs.
the original one was written in C around 11 years ago, the sole reason i rewrote this one is for learning Rust and making my own slightly faster version to add features later anytime i want.
also i love ps3.
According to PSDev Wiki a Bluray disc consists of sectors with a lenght of 2048 bytes.
Encryption:
- Some regions are encrypted some are not
- Usually even numbered regions are encrypted and odd numbered regions are not encrypted
- the encryption used is AES-128 in CBC mode with no padding
What is simply done is using a decryption key and decrypting what needs to be decrypted as for the rest its directly written to disk without keeping the data in memory.
Decrypting MX vs. ATV Untamed (USA) in less than 2 seconds on a fast enough rig! sometimes increasing the thread count too high might add a slight overhead for the dec process to start.
Please bear in mind this demonstration is done on some very idealistic conditions with a very good CPU and a good SSD.

| Option | Description | Note |
|---|---|---|
--iso |
For the ISO file | |
--dk |
For decryption key, a base-16 hex key | |
--tc |
Thread count, specifies the number of threads | Be careful with this one |
--auto |
Enables automatic key detection and decryption | Will only work if there is the key in the keys folder |
--skip |
Disables the press any key to exit after decryption |
ps3dec.exe --iso game.iso --dk yourdecryptionkey --tc 64
If you don't want to keep changing your decryption key every time you can use --auto flag , which will look inside a folder called keys containing the entire PS3 keys library which you can fetch from aldostools dkey database here Aldostools dkeys , to note that only .dkey files containing a base-16 hex key are compatible.
ps3dec.exe --iso game.iso --auto --tc 64
If you visit the releases page you might find two types
- Stable == ready to use, reliable enough.
- Preview == trying out requests, and toying around before stable.
