Let us learn more about ceph block storage encryption and how to set it up. With the support of our Server management support services at Bobcares we will now go through a complete note on how to set it up.

What is ceph block storage encryption?

Ceph is a software-defined storage platform that is open source and provides object, block, and file storage. Ceph Block Storage Encryption is a feature in Ceph that enables users to encrypt data at the block level. It encrypts data before writing it to the storage cluster and decrypts it when retrieving it.

Block storage encryption adds an extra degree of protection to sensitive data stored on Ceph. The encryption is done per-volume, so the user may select which volumes to encrypt and which to leave unencrypted.

How to enable ceph block storage encryption?

The following are the general procedures to enable Ceph block storage encryption:

1. Set up a key management system (KMS). To encrypt and decrypt data, the user must first establish a KMS to produce and manage the encryption keys. Ceph has numerous KMS choices, including the built-in Ceph KMS, Barbican, and Vault.
2. Create a key for encryption. After configuring the KMS, a user can generate an encryption key that will be used to encrypt data in Ceph. The KMS generates the key, which should be safely kept.
3. On the OSD, enable encryption. Encryption on the Object Storage Daemon (OSD) may be enabled by setting the osd encrypt configuration option to true. This instructs Ceph to encrypt data before writing it to the storage cluster.
4. Make a pool that is encrypted. While building a new pool in Ceph, Auser can construct an encrypted pool by specifying the pgp num and pg num parameters. These choices define the pool’s placement groups and principal OSDs, respectively.
5. Make a volume that is encrypted. Lastly, a user can construct an encrypted volume in Ceph by defining the volume’s encryption key and pool. When data is written to the disk, it is automatically encrypted with the provided key.

After completing these procedures, the user may write data to the encrypted volume in Ceph, which will automatically encrypt it before being written to the storage cluster. When data is recovered from the volume, it is decrypted automatically using the encryption key obtained from the KMS.
