gpg-hardcopy is a program to export your PGP key pairs to a nicely formatted printable PDF file. It supports three types of exports:
- Public keys
- Revocation certificates
- Secret keys
The Nix flake in this repository provides a package for the program.
The supported way to run gpg-hardcopy outside of NixOS is using the nix run command:
nix run github:impl/gpg-hardcopy -- --help
To interactively export each available component of a key pair to the file export.pdf:
nix run github:impl/gpg-hardcopy -- --export=public-key,revocation-cert,secret-key export.pdf
