SigningAlgorithmCount (2 bytes): The number of signing algorithms in the SigningAlgorithms array. This value MUST be greater than zero.
SigningAlgorithms (variable): An array of 16-bit integer IDs specifying the supported signing algorithms. These IDs MUST be in an order such that the most preferred signing algorithm MUST be at the beginning of the array and least preferred signing algorithm at the end of the array. The following IDs are defined.
