xkpasswd-rs

XKCD password generator, written in Rust with supports for Wasm in mind.

Acknowledgement

This project is highly inspired by:

• XKCD's Password Strength comic,
• xkpasswd.net and
• HSXKPasswd Perl module.

Words list for different languages are reused from FrequencyWords.

Assets for the Web app:

• Logo from infos-geek.com.
• Memes from the Internet.

Supported languages

• English
• French
• German
• Portuguese
• Spanish

To update or add language assets, run:

$ make language-assets

CLI app

Test and build

• To test the Rust code and (simple) integration of Wasm module:

  $ make test

• To build:

  $ make build

• To run all:

  $ make

Then the CLI app will be available at ./target/release/xkpasswd

Notes: all the languages will be bundled in the binary runtime.
