seal stanza

The seal stanza configures the seal type to use for additional data protection, such as using HSM or Cloud KMS solutions to encrypt and decrypt the root key. This stanza is optional, and in the case of the root key, OpenBao will use the Shamir algorithm to cryptographically split the root key if this is not configured.

Configuration

Seal configuration can be done through the OpenBao configuration file using the seal stanza:

seal [NAME] {
  # ...
}

For example:

seal "pkcs11" {
  # ...
}

For configuration options which also read an environment variable, the environment variable will take precedence over values in the configuration file.
