Image encryption

Edit online

Learn how to set a secret key that is used to encrypt a specific RADOS Block Device (RBD) image. Image level encryption is handled internally by RBD clients.

Note:
  • The krbd module does not support image level encryption.
  • You can use external tools such as dm-crypt or QEMU to encrypt an RBD image.
