[token]

# additional setup. If using `fernet`, you're required to run `keystone-manage
# fernet_setup`, which creates symmetric keys used to encrypt tokens. If using
# `jws`, you're required to generate an ECDSA keypair using a SHA-256 hash
# algorithm for signing and validating token, which can be done with `keystone-
# manage create_jws_keypair`. Note that `fernet` tokens are encrypted and `jws`

# This option is deprecated for removal since S.
# Its value may be silently ignored in the future.
# Reason: Keystone already exposes a configuration option for caching tokens.
# Having a separate configuration option to cache tokens when they are issued
# is redundant, unnecessarily complicated, and is misleading if token caching
