Mema Vault

Prerequisites

• Master Key: Must be set as an environment variable MEMA_VAULT_MASTER_KEY.
• Dependencies: Requires cryptography Python package.

Core Workflows

1. Store a Secret

Encrypt and save a new credential.

• Usage: python3 $WORKSPACE/skills/mema-vault/scripts/vault.py set <service> <user> <password> [--meta "info"]

2. Retrieve a Secret

Fetch a credential. By default, the password is masked in output.

• Usage: python3 $WORKSPACE/skills/mema-vault/scripts/vault.py get <service>
• Show Raw: Use --show flag only when required for secure injection.

3. List Credentials

• Usage: python3 $WORKSPACE/skills/mema-vault/scripts/vault.py list

Security Standards

• Encryption: AES-256 CBC via PBKDF2HMAC (480,000 iterations).
• Masking: Secrets are masked in standard logs/output unless explicitly requested.
• Isolation: The Master Key should never be stored in plaintext on disk.
