About:
PIUS (PGP Individual UID Signer) is a command-line tool designed to automate the process of signing all UIDs on a PGP/GnuPG keyring. It streamlines the web-of-trust establishment by allowing users to quickly sign keys, optionally filtering by key size or email domains to avoid signing potentially weak or spam keys.
Key Features:
  • Automated batch signing of PGP UIDs
  • Configurable filters for key strength and email domains
  • Interactive mode for manual verification
  • Support for GnuPG keyrings
Use Cases:
  • Establishing trust within a PGP web-of-trust network
  • Verifying and signing a large number of keys at a keysigning party
  • Automating key maintenance for security teams
Alternatives:
  • caff – Part of the signing-party package, offers more granular control over individual keys but can be more complex to configure for bulk operations.
  • GnuPG (gpg) – The underlying tool, requires manual command entry for each UID or key, whereas PIUS automates the repetitive workflow.
