VFDecrypt is a program originally intended to decrypt FileVault-encrypted images. It is capable of decrypting the root filesystem image of iOS, with the appropriate key.


Each build is different. To get the syntax for your build, run the program with no arguments. Some builds require the parameters to be in the exact order as above (-i-k-o). Most builds require there be no space between the option and the parameter (i.e. -kf43e, not -k f43e).
