# `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
|
|
master key. This stanza is optional, and in the case of the master key, Vault
|
|
will use the Shamir algorithm to cryptographically split the master key if this
|
|
is not configured.
|
|
|
|
As of Vault 0.9.0, the seal can also be used for [seal wrapping][sealwrap] to
|
|
add an extra layer of protection and satisfy compliance and regulatory requirements.
|
|
This feature is only available in Vault Enterprise.
|
|
|
|
For more examples, please choose a specific auto unsealing technology from the
|
|
sidebar.
|
|
|
|
## Configuration
|
|
|
|
Seal configuration can be done through the Vault configuration file using the
|
|
`seal` stanza:
|
|
|
|
```hcl
|
|
seal [NAME] {
|
|
# ...
|
|
}
|
|
```
|
|
|
|
For example:
|
|
|
|
```hcl
|
|
seal "pkcs11" {
|
|
# ...
|
|
}
|
|
```
|
|
|
|
For configuration options which also read an environment variable, the
|
|
environment variable will take precedence over values in the configuration file.
