.call(length: ApiKeys.configuration.token_length, prefix: ApiKeys.configuration.token_prefix.call, alphabet: ApiKeys.configuration.token_alphabet) ⇒ String

Generates a new token string.

Parameters:

  • length (Integer) (defaults to: ApiKeys.configuration.token_length) —

    The desired byte length of the random part (before encoding).

  • prefix (String) (defaults to: ApiKeys.configuration.token_prefix.call) —

    The prefix to prepend to the token.

  • alphabet (Symbol) (defaults to: ApiKeys.configuration.token_alphabet) —

    The encoding alphabet (:base58 or :hex).

Returns:

  • (String) —
