spieker/tokens

# This provides a method for generating a random token of the given length.
# The generated token is base58 encoded, so the token just contains numbers,
# up- and down case characters.
#
# Example:
#   Object.new_token(10) # => "S2Mq4mJBv6" (i.e.)
# or
#   Object.new.new_token(10) # => "S2Mq4mJBv6" (i.e.)
#

    result = ''
    length.times do
      result += characters[SecureRandom.random_number(characters.length)].to_s
    end
    result
  end
