Key-Gen (Linux)

key-gen is an interactive, dependency-free Python 3 password and memorable-key generator. It uses Python's secrets module rather than random and provides conventional passwords with lengths from 8–32, security levels 1–25, and batches of 1–75 results.

Sample

Files

• key-gen.py — the program.
• install-key-gen.sh — installer/uninstaller for the key-gen terminal command.

The art and signature are automatically centered at the top of the loading screen and interactive screens.

Install on Linux

Open a terminal in the directory containing both files.

Per-user installation (recommended; no sudo)

chmod +x install-key-gen.sh
./install-key-gen.sh --user

If the installer says ~/.local/bin is not in your PATH, add this line to ~/.profile:

export PATH="$HOME/.local/bin:$PATH"

Then close and reopen the terminal (or run source ~/.profile).

System-wide installation

This places the command in /usr/local/bin:

chmod +x install-key-gen.sh
sudo ./install-key-gen.sh --system

This approach works on most Linux distributions because it needs only a POSIX shell, Python 3, and the standard install command. It does not depend on a particular package manager.

Use

Start the TUI:

key-gen

It first asks you to choose a mode:

1. Secure password — choose password length (8–32), security level (1–25), and result count (1–75).
2. Memorable key — choose 4–12 randomly selected words, a separator (-, ., or _), and result count (1–75).

A memorable key looks similar to:

snow-rabbit-tulip-bluebird-daisy-dawn-citrus-stone

The words are chosen with cryptographically secure randomness. Use 8 or more words for important accounts. A conventional high-level random password is usually the better choice when a website accepts it and a password manager is available.

At any input prompt, type /exit, or press Ctrl+C, to quit.

Show the full table describing all 25 levels:

key-gen --help

Disable colors if needed:

key-gen --no-color

Uninstall

For a user installation:

./install-key-gen.sh --user --uninstall

For a system-wide installation:

sudo ./install-key-gen.sh --system --uninstall

Notes

Passwords are printed to the terminal. Do not run the tool in a shared terminal session or leave generated passwords visible on screen. Store important passwords in a reputable password manager.
