The Token is an optional text token used to name shares in order to avoid confusion in case one utilizes secret sharing to protect several independent secrets. The generated shares are prefixed by these tokens. Don't use dashes if you want to be compatible with ssss-combine in Linux. Try something like "BTC_th3" so you know that a threshold of 3 was used when generating the keys (you will need to know this later when you combine the keys).
For advanced users: Non-ASCII input (input that is not plain-text) can be used by checking the Hex input box and entering hex data (pairs of characters from the [0-9a-z] set).
Note: the set of generated shared keys is always different, even if the secret is the same. You can not combine keys from different sets and expect to recover the secret.
