veil

Single header C++23 compile-time string obfuscation library.

Usage

Wrap any string literal in VEIL(...):

#include <veil/veil.hpp>
#include <print>

auto main() -> int
{
    std::println("{}", VEIL("hi chat mraow").view());
    const auto wide = VEIL(L"wide meow");
}

Accessors:

Member	Returns	Notes
view()	std::basic_string_view<CharT>	Valid only while the string is alive.
c_str()	const CharT*	Null-terminated.
str()	std::basic_string<CharT>	An owning copy you can keep.
size()	std::size_t	Length in characters, excluding the terminator.
empty()	bool

A secure string also converts implicitly to its std::basic_string_view.

Building

To build the examples, run:

cmake -S . -B build -DCMAKE_BUILD_TYPE=Release
