Plugin: Secure Evidence Packaging, Encryption, Hashing & Delivery to Auditors

[ethanolivertroy]

Feature Description

Create a plugin/workflow for securely packaging, encrypting, hashing, and transmitting compliance evidence to auditors and regulators.

Proposed Capabilities

Evidence Packaging

• Zip up evidence artifacts (logs, screenshots, config exports, policy documents)
• Support multiple compression/archive formats (zip, tar.gz)
• Preserve directory structure and metadata (timestamps, file permissions)
• Optional manifest/index file listing all included evidence with descriptions

Encryption Methods

• GPG - Encrypt evidence bundles using GPG/PGP public keys of auditors
• PGP - Alternative PGP encryption for compatibility with auditor key preferences
• 1Password CLI - Leverage 1Password CLI (op) for secure key management and encryption workflows

Integrity Verification

• Generate cryptographic hashes (SHA-256/SHA-512) for all evidence files
• Create signed checksum manifest
• Support detached signatures for tamper-evident delivery

Delivery Methods

• Secure file share links
• Direct encrypted email attachments
• SFTP/SCP upload to auditor drop boxes
• API integration with auditor evidence portals

Workflow Integration

• Plugin architecture compatible with Hermes Agent workflows
• CLI commands and automated pipeline steps
• Integration with GRC evidence collection pipelines
• Audit trail logging of all packaging, encryption, and delivery actions

Motivation

GRC practitioners frequently need to securely share evidence with external auditors, regulators, and assessors. A standardized, automated plugin would reduce manual effort, ensure consistent security controls, and maintain chain of custody for compliance artifacts.

Alternatives Considered

Manual ad-hoc scripts for each audit engagement (current state, error-prone and inconsistent).
