Awesome work from JjKkYu (as usual)!

Here are 2 tips to find the dev_klic even faster:

1- First try to bruteforce the edat against the list of known: ps3tools.aldostools.org/dev_klics.txt

2- If the key is not found above, open the eboot.bin with scetool and show the info. Then open the ELF with HxD and cut from the offset 0 to the offset of the 3rd section.

Usually this will reduce the "devklic source file" (elf) to about a 50% or less of the original size, saving a lot of time.

To quote: This tool is used to bruteforce devklic for edat files on pc. It supports bruteforcing from binary or text files. It only take minutes to bruteforce in an elf file, no more waiting for hours or days.

This tool is based on BuC's EDAT Devklic Validator, all credit to BuC.

Update to v1.1

  • Fix a bug while bruteforce in text file.

If you meet some issue, please feedback. Thx.

Update to v1.2

Add 2 Modes:

  • Short Mode: Run only 4 rounds for binary source file. This mode doesn't try all the contents from source file. But it is enough in most cases.
  • Line Mode: Run only 1 round for text source file. This mode reads first 32 bytes in each line as devklic. It runs extremely fast for formatted text source file.
