Re-explain

Static Secrets:

  • Pre-existing secrets stored in Vault (like API keys, passwords)
  • Values remain constant until manually updated
  • Stored in Key-Value (KV) secret engines
  • Example: Storing a third-party API key that doesn't change frequently

Dynamic Secrets:

  • Generated on-demand by Vault when requested
  • Have configurable Time-To-Live (TTL)
  • Automatically expire and are cleaned up
  • Significantly reduce credential exposure risk

Example: Database credentials generated when an application needs database access, valid for only 1 hour, then automatically revoked.

# Static secret example
vault kv put secret/api-keys stripe_key="sk_test_123456"

# Dynamic secret example (requires database engine setup)
vault read database/creds/readonly
