Rust-VPK

A tool to create, list, check, and unpack VPK files files.

Under Linux this tool can also be used to mount VPK packages as read-only FUSE filesystem.

This is similar to another tool I wrote, but this time in Rust instead of C++ (for the fun of it!).

Limitations

Checking and generating of cryptographic signatures is not supported, since there's no information out there on how to do that.

I don't know if the offsets in the archive MD5 sum entries need to be adjusted for the data embedded in the _dir.vpk file, like it has to be for the offsets of the file entries. Currently I assume they don't. If that is wrong I generate wrong VPK v2 packages and make mistakes checking VPK v2 packages, but only if there is data inside the _dir.vpk file in the data section (i.e. not inlined directly in the index). I don't have a game that does that, so I can't check.

Usage

USAGE:
    vpk [SUBCOMMAND]

FLAGS:
    -h, --help
            Prints help information

    -V, --version
            Prints version information


SUBCOMMANDS:
    check     Check CRC32 and MD5 sums of files in a VPK package.
    help      Prints this message or the help of the given subcommand(s)
    list      List content of a VPK package.
    mount     Mount a VPK package as read-only filesystem.
    pack      Create a VPK package.
    stats     Print some statistics of a VPK package.
    unpack    Extract files from a VPK package.

For usage information about a sub-command type vpk help $SUBCOMMAND, e.g. vpk help list.

Build

Linux:

cargo build --release

Other operating systems:

cargo build --no-default-features --release

Cross compile to Windows:

cargo build --target x86_64-pc-windows-gnu --no-default-features --release

--no-default-features is needed to not try to build FUSE support. I don't know how to make default features target specific. I think it's not yet possible.

TODO

• Find out if the archive MD5 sum offsets for the _dir.vpk archive need to be adjusted like they do for file entries. Currently I assumed they don't, but I don't have a game that uses VPK v2 and embeds any data in the _dir.vpk file (outside the data directly inlined in the index) to verify. Don't know how I would find that out.
• Read and evaluate signatures from VPK v2 files? Algorithm used is unknown. Don't know how I would find that out.
