Unable to create databags in chef

I am very new to chef and trying to secure passwords using databags. Unfortunately, I tried in different ways but unable to succeed. I followed different tutorials first and second. I understood only two steps but later on I was unable to move forward.

• I created secret key using openssl

• In link1 step 2 says knife data bag create passwords mysql --secret-file /tmp/my_data_bag_key

but I don't know where it is creating the databag.

Can some one guide me from step two? I am trying to secure my database password. I got stuck after creating secret file.

I'm using the following ruby script to encrypt/decrypt chef data bags locally:

to encrypt:

ruby encrypt.rb PATH_TO_SECRET_FILE ENCRYPTED_DATA_BAG.json

and to decrypt:

ruby decrypt.rb PATH_TO_SECRET_FILE DECRYPTED_DATA_BAG.json
