Securing Project Secrets

"Project secrets" are any credentials or secrets required for executing the project's ELT functions. Project secrets are encrypted using the customer organization's dedicated public encryption key before submitting to Meltano.

Credential security FAQ

How are secrets protected?

  1. Project secrets will always be encrypted, in transit and at rest.
  2. Meltano will never store your secrets in clear text.
  3. Meltano engineers do not have access to directly decrypt your secrets.
  4. The decryption key for project secrets will never leave AWS servers.
  5. Our IAM policies only allow the decrypt action within containers that are running project workloads or for services that require specific secrets to perform tasks such as sending notifications to your webhook urls.
  6. Meltano uses envelope encryption strategy with AWS KMS keys to encrypt your secrets.
What encryption algorithms are used?

The algorithm for encrypting secrets is an AES symmetric encryption, using 256-bit AES-GCM encryption keys.
