Tumpa is an effort to create a simple GUI desktop application to create OpenPGP keys with sane defaults, and moving them into smartcards (we tested with Yubikey 5 and Nitrokey 3) via just a click.

Development setup

• Install Rust following rustup instructions.
• cargo install just we use just for making life easy.
• just install to install the dependencies via pnpm.
• just dev to build and run the application locally.

Hardware support

Yubikey 4 and Yubikey 5 and Nitrokey 3 can be used with Tumpa.
