def initialize uri, algorithm: "RS256", retry_interval: nil

Parameters:
  • retry_interval (Integer, nil) -- Override the retry interval in
  • algorithm (String) -- The algorithm to use for signature
  • uri (String, URI) -- The URI from which to download keys. 
def initialize uri, algorithm: "RS256", retry_interval: nil
  super uri, retry_interval: retry_interval
  @algorithm = algorithm
end

def interpret_json data

Raises:
  • (Google::Auth::IDTokens::KeySourceError) - If X509 certificates cannot be parsed

Returns:
  • (Array) - Array of key info objects

Parameters:
  • data (Hash) -- The JSON data containing certificate strings
