The Application Property Template included in the response to the SELECT command optionally includes a tag 0xAC, which indicates what cryptographic algorithms the PIV Card Application supports. The presence of algorithm identifier '27' or '2E' indicates that the corresponding cipher suite is supported by the PIV Card Application for secure messaging and that the PIV Card Application possesses a PIV Secure Messaging key of the appropriate size for the specified cipher suite.
