Encryption Tools

The Encryption Tools skill provides a practical cryptography toolkit accessible through natural language commands. Encrypt individual files or entire directories using AES-256-GCM, ChaCha20-Poly1305, or RSA-OAEP with key sizes up to 4096 bits. Decrypt files using the matching key material, which can be a passphrase-derived key or a key file. PGP/GPG operations are supported — generate key pairs, import and export public keys, sign messages, verify signatures, and encrypt messages to a recipient's public key. For developers, the skill can generate secure random tokens, UUIDs, and API keys of configurable length and character set. Hash computation covers MD5 (legacy comparison only), SHA-256, SHA-512, and BLAKE3. HMAC generation and verification for API request signing is available. Key derivation from passphrases uses Argon2id with configurable memory and iteration parameters. The skill keeps all operations local — no keys or plaintext leave your machine. Integrates with the File Manager skill to encrypt backups before off-site storage.
