EncryptEd

EncryptEd is a small encrypted text editor with a FLTK GUI and a C17 core for UTF-8 text files stored in a compressed and encrypted .txx format.

Build

cmake -S . -B build
cmake --build build
ctest --test-dir build --output-on-failure

Windows Installer

After configuring a Windows-target build directory that produces the encryptEd GUI target, build the NSIS installer with:

cmake --build <build-dir> --target package_windows_installer

Requirements:

• NSIS 3.x with makensis available on the packaging host.
• A Windows build where the encryptEd GUI target is enabled.

The installer stages only the GUI application into <build-dir>/windows-installer/ and emits encryptEd-<version>-windows-setup.exe. It defaults to a per-user install under %LocalAppData%\Programs\EncryptEd, offers an all-users option in the same setup, creates a Start Menu shortcut, and associates .txx files with EncryptEd.

Because the same installer can switch to an all-users install, Windows may request elevation when an administrator-capable account launches setup. The CLI prototype is not included in this installer.

CLI Prototype

build/encrypted_cli pack input.txt output.txx
build/encrypted_cli unpack output.txx restored.txt

printf '%s\n' "$PASSPHRASE" | build/encrypted_cli pack input.txt output.txx --password-stdin

The CLI exists to exercise the core format alongside the desktop editor. By default it prompts for the passphrase without echoing it; use --password-stdin for scripts.

Vendored Dependencies

• lib/microz: stripped miniz-derived raw DEFLATE support, kept as the compression layer. Committed to this repo — it's a modified derivative (ported to C17, archive APIs stripped), not a redistributed vendor copy, released under microz's original MIT license.
• lib/monocypher: Monocypher 4.0.2 for Argon2id and XChaCha20-Poly1305. Not committed — download it from https://monocypher.org/download/ and place monocypher.c and monocypher.h in lib/monocypher/. CMake fails with instructions if it's missing.
• FLTK 1.5 (GUI only): not committed — build it as a static library and place it at lib/fltk/1_5/fltk-linux/ (or fltk-win64//fltk-win32/ for Windows cross-builds); see https://www.fltk.org/software.php. Without it, CMake skips the encryptEd GUI target but still builds the core library, CLI, and tests.
