Hi All ,

What is the use of the mode attribute ? what does the value of this
attribute signify and what are the possible values of this attribute?
For ex :Consider the order request to create the secret :

POST v1/orders

Header: content-type=application/json
        X-Project-Id: {project_id}
{
  "type": "key",
  "meta": {
    "name": "secretname",
    "algorithm": "AES",
    "bit_length": 256,
    "mode": "cbc",
    "payload_content_type": "application/octet-stream"
  }
}


What does the mode  value "cbc " indicate ?
