About time I put this on pouët I guess.

vondehi is an in-memory decompression stub, using the system decompressors available (that is, gzip or xz). It's a bit larger than a shell script, but this approach doesn't touch the filesystem at all, using the memfd_create and exeveat syscalls. It's also not a custom compressor/decompressor (such a thing is coming Soon™).

Usage: compile vondehi.asm with "nasm -fbin", and prepend your gzip- or xz-compressed payload with it. A more in-depth explanation and options (some of which you might want to enable) can be found in the README.md file included in the download archive.

It was used in all the prods tagged with 'vondehi' on Demozoo, including Access Control and International Shipping.

raer: coming soon ;)

(smol (the dynamic linker thing) will be submitted once a few more bugs are fixed, unlord is working on his compressor, and I should also make a kkapture-style capturing tool)
