GPG Key Migration Toolkit

Purpose

Securely migrate GPG keys (public, private) and their trust settings between machines, preserving trust relationships.

Description

This toolkit consists of two Bash scripts:

• gpg-export-all-with-trust.sh: Exports all GPG keys and trust settings from a source machine.
• gpg-import-all-with-trust.sh: Imports the exported keys and trust settings into a destination machine.

For full details, see the file: specs.md.
