GPG / PGP Signing

Overview

QCecuring integrates with GPG/PGP signing workflows to provide centralized governance over signing keys used for software packages, Git commits, and file integrity verification. Organizations gain visibility and control over GPG key usage without disrupting existing signing practices.

Key capabilities

• Centralized inventory of GPG/PGP signing keys with ownership and expiration tracking.
• Secure key storage with controlled access for authorized signing operations.
• Automated key rotation and subkey management following organizational policies.
• Integration with package managers for signed RPM, DEB, and other Linux package formats.
• Audit trail of all GPG signing operations with signer identity and artifact metadata.

Typical use cases

• Linux distribution teams signing packages with GPG keys requiring lifecycle governance.
• Development teams using GPG for Git commit and tag signing with managed keys.
• Organizations distributing software with GPG signatures needing key rotation automation.

High-level integration flow

1. Import or generate GPG signing keys within QCecuring’s secure key management infrastructure.
2. Configure access policies specifying which users and systems can perform signing operations.
3. Signing requests are submitted through QCecuring’s API, which performs GPG operations securely.
4. Signed artifacts and detached signatures are returned to callers without exposing private keys.
5. Key lifecycle events including rotation, revocation, and expiration are managed centrally.
