Here we are going to attach board keys to a message being sent.
When you click on the icon highlighted in yellow, a small window
opens showing available keys in your keypool folder/directory. In
this example myboard.key has been chosen. After selecting
it, click Open. If you are selecting to add a board key file that
contains both a public and a private key, you will receive a warning
message:
Here you can decide if you wish the
private key attached to your message or not. You can safely
exchange your private board key with another 'trusted' user by signing
and encrypting the entire message and publishing to a board that you
have the private key to. The recipient must at least have your
public key to receive the message naturally. Once again, these are
all examples and you can over time probably come up with a number of
combinations for using the tools that are provided with frost.
Once you have your keys attached, then
proceed as normally to 'send' your message using frost.
