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.
