ExternalCryptoKeyID Property (DTLSClient Class)

The ID of the pre-shared key used for DC request authentication.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* GetExternalCryptoKeyID();
int SetExternalCryptoKeyID(const char* lpszExternalCryptoKeyID);

Unicode (Windows)
LPWSTR GetExternalCryptoKeyID();

int secureblackbox_dtlsclient_setexternalcryptokeyid(void* lpObj, const char* lpszExternalCryptoKeyID);

QString GetExternalCryptoKeyID();
int SetExternalCryptoKeyID(QString qsExternalCryptoKeyID);

Default Value

""

Remarks

The ID of the pre-shared key used for DC request authentication.

Asynchronous DCAuth-driven communication requires that parties authenticate each other with a secret pre-shared cryptographic key. This provides an extra protection layer for the protocol and diminishes the risk of the private key becoming abused by foreign parties. Use this property to provide the pre-shared key identifier, and use ExternalCryptoKeySecret to pass the key itself.

The same KeyID/KeySecret pair should be used on the DCAuth side for the signing requests to be accepted.

Note: The KeyID/KeySecret scheme is very similar to the AuthKey scheme used in various Cloud service providers to authenticate users.

Example:

 
 Copy
  signer.ExternalCrypto.KeyID = "MainSigningKey";
  signer.ExternalCrypto.KeySecret = "abcdef0123456789";

Data Type

String
