[kms_keymaster]
|
|
# The kms_keymaster section is used for configuring a keymaster that retrieves
|
|
# the encryption root secret from an external key management system (kms),
|
|
# using the Castellan abstraction layer. Castellan can support various kms
|
|
# backends that use Keystone for authentication. Currently, the only
|
|
# implemented backend is for Barbican.

# Over time, the format of crypto metadata on disk may change slightly to resolve

# The api_class tells Castellan which key manager to use to access the external

# key management system. The default value that accesses Barbican is

# api_class = castellan.key_manager.barbican_key_manager.BarbicanKeyManager

|
# The configuration options below apply to a Barbican KMS being accessed using

|
# Castellan. If another KMS type is used (by specifying another value for

|
|
# documentation.

# The key_id is the final part of the secret href returned in the
|
