Crate pentacle

pentacle is a library for executing programs as sealed anonymous files on Linux, using memfd_create(2).

This is useful for executing programs that execute untrusted programs with root permissions, or ensuring a cryptographically-verified program is not tampered with after verification but before execution.

The library provides a wrapper around Command as well as two helper functions for programs that execute sealed versions of themselves.

fn main() {
    pentacle::ensure_sealed().unwrap();

    // The rest of your code
}

Structs
