Advanced Usage

Environment Variable Support

For automation and CI/CD, you can use the PASSWORD_MANAGER_MASTER_PASSWORD environment variable:

bash

# Set environment variable
export PASSWORD_MANAGER_MASTER_PASSWORD="your-master-password"

# Now you don't need to enter password interactively
password-manager list
password-manager add --name "github" --type "token" --password "ghp_xxx"
password-manager change-password --old "old-pass" --new "new-pass"

Security Note: Be cautious when using environment variables in shared environments, as they may be visible in process lists.

Cache Auto-Rebuild

When the cache file is missing or expired, the password manager will automatically attempt to rebuild it:

Cache Missing: If .cache/key.enc doesn't exist, the system will try to rebuild from the provided password
Environment Variable: If PASSWORD_MANAGER_MASTER_PASSWORD is set, it will be used for cache rebuild
Interactive Prompt: If no environment variable, you'll be prompted to enter the password

bash

# First run after cache expiration
$ password-manager list
🔒 Cache missing, attempting to rebuild...
✅ Cache rebuilt successfully

# Subsequent runs (within 48 hours)
$ password-manager list
✅ Using cached key (expires in 47h 59m)

Configuration

config.json includes reasonable defaults and can be used directly. Edit for customization:

json

{
  "cacheTimeout": 172800,          // Master password cache timeout (seconds, default: 48 hours)
  "maxHistoryVersions": 3,         // Number of historical versions to retain
  "auditLogLevel": "all",          // all/sensitive/none
  "autoDetect": {
    "enabled": true,               // Enable sensitive information detection
    "sensitivityThreshold": "medium",
    "askBeforeSave": true
  },
  "requireConfirm": {
    "delete": true,
    "deleteAll": true,
    "export": true,
    "backup": true,
    "restore": true
  },
  "generator": {
    "defaultLength": 32,
    "includeUppercase": true,
    "includeNumbers": true,
    "includeSymbols": true
  }
}

Tip: If configuration is modified incorrectly, refer to config.example.json to restore defaults.

Security Documentation

Implemented Security Measures

AES-256-GCM Encryption - Military-grade encryption protection
PBKDF2 Key Derivation - 100,000 iterations
Dual Encryption - Vault and cache encrypted separately
Unbiased Random Numbers - Uses crypto.randomInt()
Input Validation - Sanitization at all entry points
Sensitive Operation Confirmation - Re-enter password for deletion
Memory Cleanup - secureWipe() removes sensitive data
Audit Logs - Records operations without content

Security Recommendations

Master Password: Cannot be recovered if lost, store securely
Regular Backups: Backup to external storage weekly
Strong Master Password: Use 16+ character random password or passphrase
Lock Promptly: Manually lock when not in use for extended periods
Protect Configuration: Do not upload config.json to public repositories
Audit Logs: Regularly check .logs/detection.jsonl

Remaining Risks

Risk	Likelihood	Impact	Mitigation
Cache file depends on filesystem permissions	Low	Medium	Encrypted
Memory keys may be dumped	Low	High	secureWipe added
Master password loss cannot be recovered	-	High	User education
