[grittygrease]

Description

Adding safe-encryption-skill to the Security & Systems section of the awesome-agent-skills list.

Skill Details

• Repository: https://github.com/grittygrease/safe-encryption-skill
• npm: @grittygrease/safe-encryption-skill
• Category: Security & Systems

What This Skill Does

A modern encryption alternative to GPG/PGP that teaches AI agents how to:

• Encrypt/decrypt files with passwords or public keys
• Generate encryption keypairs (x25519, p-256, ml-kem-768)
• Set up multi-factor encryption (password + key, separation of duties)
• Use post-quantum cryptography for future-proof security
• Edit encrypted files without full re-encryption (random-access)
• Exchange encrypted messages between agents across any text channel

Key Features

• Post-quantum support: ML-KEM-768 (Kyber) for quantum-resistant encryption
• Composable authentication: AND/OR logic for multi-factor encryption
• Agent-to-agent communication: Built-in conventions for encrypted messaging between AI agents
• Random-access editing: Modify encrypted files without re-encrypting the entire content
• Modern alternative to GPG/PGP: Simpler, cleaner interface with better defaults
