[chef] Encrypted Data Bag format?

[Guy Matz < >]

The format of my encrypted data bag seems to have changed from

{

  "abc": "Aizug0hk7OmzAk1feN8u5jxsDn8oYHfE8gOdga1EmpQ=\n",

}

to this:

"abc": {

    "iv": "/2ZxMWiIVWJzpWRj+8uxJA==\n",

    "cipher": "aes-256-cbc",

    "version": 1,

    "encrypted_data": "0uKackLYg25J6Eoow5LhbkvOGEleT7XT/ueraSwnqB/obRDtASu1qOImuimm\n9MqF\n"

  },

Anyone know what I might have done to my DB, or if an upgrade may have made this change?

Thanks a lot!

Guy
