PSVita PKG Tool is Available, Decrypt and Extract PS Vita PKG Files
Following up on the PS Vita .PKG xTractor 1.00 Homebrew App previously released by SKFU, today PlayStation Vita homebrew developer PsDev has made available a PSVita PKG Tool v1.0 that can also be used to decrypt and extract PS Vita PKG files.
To quote: One day I was going to decrypt and extract the 1.00 Ridge Racer PKG. I went to download SKFU PKG xTractor and found out it was upload through MegaUpload. I look on the Internet to see if I could find any other sources where this could be uploaded to and was not successful at finding it.
So I made this, it was for personal use, but... Why waste time when I could release this for other people that don't have his tool and want to do the same thing? So here it is.
This little tool can decrypt and extract PsVita beta/retail pkg under 1.00. it uses the PSP AES key used to decrypt and extract PSP retail PKG
No longer can pkg over beta/retail 1.00 be decrypted and extracted with this Aeskey, but it can be decrypted with a PS3. The only thing with that is you gotta know how to do it because, 3.55 cannot do this (as far as I know, may be wrong). But there still away, (maybe release another day).
