     # 1. Encrypt and save the binary content to a file:
-    $ aws kms encrypt --key-id $KMS_KEY_ID --plaintext "<here-you-can-paste-your-pwd>"  --query CiphertextBlob --output text | base64 -d > /tmp/encrypted

     # 2. Then feed this encrypted content back to decrypt.  Note that the Plaintext that comes back is base64 encoded so we need to decode this.

 If all works we can now repeat the first step without the base64 encoding:
