VA-003 Explain encryption as a service Practice Question
Which THREE are appropriate use cases for Vault's Transit secrets engine?
⚠ Common exam trap
HashiCorp often tests the distinction between Transit (encryption as a service) and other secrets engines like PKI (certificates) and KV (static secrets), so candidates mistakenly associate Transit with any cryptographic task, including certificate management or secret storage.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Providing cryptographic offloading for applications running in untrusted environments
The Transit secrets engine performs encryption and decryption operations entirely on the server side, never exposing the encryption keys to the client. This allows applications running in untrusted environments to offload cryptographic processing securely, as the keys remain within Vault's encrypted storage and are never transmitted to or stored by the application.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Providing cryptographic offloading for applications running in untrusted environments
Why this is correct
Transit allows secure crypto operations without exposing keys to the application.
- ✗
Generating and managing TLS certificates for internal services
Why it's wrong here
This is handled by the PKI secrets engine.
- ✗
Storing and retrieving static secrets like API keys
Why it's wrong here
Static secrets are stored in the KV secrets engine, not Transit.
- ✓
Performing signing and verification operations (e.g., for digital signatures)
Why this is correct
Transit supports HMAC and signing with asymmetric keys.
- ✓
Encrypting sensitive fields in a database without exposing encryption keys to the application
Why this is correct
Classic use case for Transit encryption as a service.
