It is produced +in kernel using the CAAM crypto engine. Userspace can only see +the blob for the corresponding key. All the blobs are displayed +or loaded in hex ascii. + +Secure key can be created on platforms which supports CAAM +hardware block. Secure key can also be used as a master key to +create the encrypted keys along with the existing key types in +kernel. + +Secure key uses CAAM hardware to generate the key and blobify its +content for userspace.
