Buffer that holds the authentication data.
The length of the authentication data, in bytes. The method will fail if this is not in the range 1 to 128.
Every ISCL-compliant entity must have between 1 and 128 bytes of authentication data. This authentication data is exchanged between the client and the server during the mutual authentication process. This method sets an array of 1 to 128 bytes that contains the authentication data. The authentication data is data exchanged in plain text. After the mutual authentication process, the communication entities can verify the authentication data of the other entity (client or server) and, if the authentication data is wrong, can close the connection.
For an example, refer to SetIsclMutualAuthenticationAlgorithm.
