Configuration
Master Key (Required)
Set your master encryption key via environment variable:
export VAULT_MASTER_KEY="your-secure-master-key-here"
Or in your OpenClaw config:
{
"plugins": {
"vault": {
"masterKey": "your-secure-master-key-here",
"storageFile": ".vault/passwords.json"
}
}
}
Options:
masterKey- Master encryption key (can also use VAULT_MASTER_KEY env var)storageFile(default:.vault/passwords.json) - Storage file path relative to home directory
⚠️ Important: Keep your master key secure! Without it, you cannot decrypt stored passwords.
Security
🔒 Encryption Details:
- Algorithm: AES-256-GCM (Galois/Counter Mode)
- Key Derivation: scrypt with random salt per password
- IV: Random 12-byte initialization vector per password (GCM recommended size)
- Salt: Random 32-byte salt per password, stored with encrypted data
- Authentication: GCM authentication tag for integrity verification
Security Best Practices:
- Use a strong, unique master key (minimum 32 characters recommended)
- Store master key securely (environment variable or secure config)
- Set strict file permissions:
chmod 600 ~/.vault/passwords.json - Add
.vault/to your.gitignore - Never commit your master key to version control
- Use system-level disk encryption for additional protection
- Backup your master key securely - lost keys mean lost passwords
Suitable for:
- Development/testing credentials
- API keys and tokens
- Personal passwords
- Team shared credentials (with secure key distribution)
Examples
# Save API keys
vault openai sk-proj-abc123
vault anthropic sk-ant-xyz789
# View a key
vault openai show
# Output: Password for 'openai': sk-proj-abc123
# List all keys
vault list
# Output:
# Stored passwords:
# • openai (created: 2026-02-17T..., updated: 2026-02-17T...)
# • anthropic (created: 2026-02-17T..., updated: 2026-02-17T...)
