Right, but again, assuming you don't have the knife[:secret_file] attribute set in your knife.rb, do this:
$ knife data bag create mybag
$ knife data bag from file mybag test.json --secret foo
Now you should have a data bag called 'mybag' containing an encrypted item called 'test'.
Now run:
$ knife data bag show mybag test
That will show you how the item is stored on the Chef server, i.e. encrypted.
Next, if you run:
$ knife data bag show mybag test --secret foo
It will decrypt the file and show you the output.

Lastly, if you want to check the encrypted file into Git, then just delete that test.json, then use the knife download command to download your test.json back from your Chef server -- it'll come back encrypted.

Well, I can also see the raw content by looking at my local file, since that's not encrypted either...

That’s correct. Knife will use your encryption key to de/encrypt the data in an encrypted data bag.

If you’d like to see the raw content of a data bag item, you can run this command:

knife exec -E "puts JSON.pretty_generate(api.get('/data/data_bag/data_bag_item'))"

That will output the raw JSON, pretty-printed, from your Chef Server.

To add to the confusion, if you have the `knife[:secret_file]` setting in your .knife.rb set, using the `knife data bag show` command will always display a decrypted data bag item, which can be _very_ confusing.

I'm not following. The file is unencrypted locally. Are you saying that the knife command will encrypt the local file?

Yes. You can see that for yourself, just upload your JSON file with the secret, then use the knife download command to download it back from the server, then compare your original to the one you just downloaded, you'll see how the encryption works. And then you can add the encrypted version to Git, it is safe (or at least, it's as safe as your encryption key is).

Doug,

While the file itself won’t be encrypted, it’s contents will be, so it IS safe to version the file in Git (we do in a repo that covers our data bags, environments, & roles).

Oh. Thanks for that. And, that's... terrible. :( The point is not to have the unencrypted file in git.

RE: data bags being encrypted on the Chef server and not on your local system, that's correct.
I should say that data bags themselves are not encrypted. There's no difference between a data bag and an encrypted data bag. It's the items within the data bag that are (or aren't) encrypted. Even though they're called "encrypted data bag".
If you find it a problem that what's in your local file system is not encrypted, then what you can do is upload your JSON file with the secret (as seen in your other thread I just replied to), then delete the file from your local file system, and if you want the encrypted file locally, then just download it from the Chef server, it'll be encrypted then.

Is there a known public cookbook for creating AWS security groups? I don't know about the security implications, but I'd like to try having the recipes creating the necessary security groups. Otherwise, it's a major hassle to put them into a script. AFAIK chef-metal/provisioner doesn't do security groups yet.

This one https://github.com/SearchSpring/aws_security, wants to use encrypted data bags and, well, that's a pain. I'd prefer to use IAM roles were possible. I'd never noticed before, but it looks like encrypted data bags are only encrypted on the Chef server, not on the local file system? If so, what's the point?
