Description of ephemeral storage encryption configuration options
Configuration option = Default value Description
[ephemeral_storage_encryption]

cipher = aes-xts-plain64

(String) Cipher-mode string to be used

The cipher and mode to be used to encrypt ephemeral storage. The set of cipher-mode combinations available depends on kernel support.

Possible values:

  • aes-xts-plain64 (Default), see /proc/crypto for available options.
enabled = False (Boolean) Enables/disables LVM ephemeral storage encryption.

key_size = 512

(Integer) Encryption key length in bits

The bit length of the encryption key to be used to encrypt ephemeral storage (in XTS mode only half of the bits are used for encryption key).
