PkgDecrypt: St4rkDev decrypts PKG Files
Developer St4rkDev just released PkgDecrypt for the PS Vita, a tool that lets you decrypt Vita .pkg files.
This is different from dumpers such as MaiDumpTool in that it can run directly on your computer: in other words, St4rkDev has figured out some of the decryption keys used on the PSVita and is now able to use them outside of the device.
In terms of practical use for the end user, this won’t change much for now. Decrypting packages doesn’t mean you can magically do anything with them, and with HENkaku people pretty much have full access to both homebrews and piracy already, so this doesn’t open new doors here, for now. Nevertheless, pretty good progress here and confirmation that St4rkdev is one of the handful of people who have deep understanding of the PS Vita internals.
St4rkDev also credits proxima for his help on the tool.
You can download PkgDecrypt from the dev’s github here. This is the source code so you’ll need to compile it yourself.
