Sheriff employs a so-called challenge mechanism to provide extra security. Your application can challenge Sheriff to verify
that the it is original and has not been tampered with; Sheriff can also challenge back to verify that the calling
application is original and has not been tampered with. Challenge also ensures that the parameters cannot be altered
Challenge can be enabled to add an extra level of security to the following functions: SLS_License, SLS_Request, SLS_Update and SLS_Release. To enable the challenge mode, you need to set the challenge protocol to SLS_BASIC_PROTOCOL. For example:
If you prefer not to enable challenge mode, all you need to do is to set the challenge protocol to SLS_NO_PROTOCOL. But please note that challenge must be implemented in calling function SLS_License.
To create a challenge, call SLS_CreateChallenge with your product Secret Codes and the input data stream; to verify a challenge, call SLS_VerifyChallenge.
If CSheriff class is used, calling SetSecrets method with your product Secret Codes will automatically enable the challenge mode. Otherwise, it is not enabled.
