Building

Install libsodium and libseccomp
Debian / Ubuntu: sudo apt install -y libsodium-dev libseccomp-dev
Arch & Derivatives: sudo pacman -S libsodium libseccomp

To build, simply run the makefile with:

make

or with clang CFI:

make CLANG_CFI=y

Building with Nix from flake

nix build

FreeBSD / OpenBSD

gmake

Formatting

Format the project according to .clang-format using ./format.sh or ./format.sh --check to dry run

Sandbox

Nacrypt applies a strict sandbox to itself before processing the input file. (see sandbox.c)
If this causes issues it can be disabled with the -DNO_SANDBOX CFLAG or allowed to fail with -DALLOW_SANDBOX_FAIL

Nix

nix profile install .
