[openstack-dev] Barbican : What is the difference between secret and order resource

Hello Asha,

So the last step you have is retrieving a decrypted secret from Barbican. Barbican indeed stores the secret internally encrypted using an internal KEK. When it is retrieved however, it is first decrypted by Barbican and then returned the client decrypted.

Beyond TLS to protect this information back to the client, there is also a transport key feature that has not yet been fully supported via the client library, that allows the client to select a session key that can be used to encrypt the secret between the client and Barbican.

Thanks,
John

Hi All,

 I would like to know if the keys generated  by Barbican through the order resource are  encrypted using KEKS and then stored in the secret object or is it stored in unencypted format.

Any help  would be highly appreciated.

root at barbican:~# curl -H 'Accept: application/json' -H 'X-Project-Id:12345' http ://localhost:9311/v1/orders

Please find the command and response below :

Thanks a lot  John for your response.

I also thank everyone who has been responding to my queries if I have missed someone .
There was  some problem while configuring my email .I do not receive the email response directly  from openstack Dev group.I would check the archive folder for that.
I will have a look into it

Once again , it's  nice working and collaborating with the openstack Dev -group.

Thanks and Regards,

Hello Asha,

The /v1/secrets resource is used to upload, encrypt and store your secrets, and to decrypt and retrieve those secrets. Key encryption keys (KEKs) internal to Barbican are used to encrypt the secret.

The /v1/orders resource is used when you want Barbican to generate secrets for you. When they are done they give you references to where the secrets are stored so you can retrieve them via the secrets resource above.

Hope that helps!

Thanks,
John

Subject: Barbican : What is the difference between secret and order resource

Hi All ,

What is the difference between secret and the order resource ?
Where is the key stored that is used for encrypting the payload in the secret resource and how do we access it.

According to my understanding ,

Storing/Posting  the secret  means  we are encrypting the actual information(payload)  using the key generated internally by the barbican based on the type mentioned in the secret type.
Geting the secret means we are decryprting the information and geting the actual information.

Posting the order refers to the generation of the actual keys by the barbican  and encyrpting those keys based on the algorithm and the internal key generated by barbican.
This encrypted key is referred through the secret reference and the whole meta data is referred through a order reference.

Please correct me if I am wrong.
Any help would be highly appreciated.
