AddSubkey Method
Adds a new subkey to the Key.
Syntax
ANSI (Cross Platform) int AddSubkey(int iBits, const char* lpszAlgorithm, int iExpires); Unicode (Windows) INT AddSubkey(INT iBits, LPCWSTR lpszAlgorithm, INT iExpires);
- (void)addSubkey:(int)bits :(NSString*)algorithm :(int)expires;
#define MID_PGPKEYMANAGER_ADDSUBKEY 2 SECUREBLACKBOX_EXTERNAL int SECUREBLACKBOX_CALL SecureBlackbox_PGPKeyManager_Do(void *lpObj, int methid, int cparam, void *param[], int cbparam[], int64 *lpllVal);
Remarks
Use this method to add a subkey to a key. Note that the key you are adding the subkey to needs to contain its secret counterpart to be able to sign the new subkey.
Bits specifies the number of bits in the new subkey, Expires is the new subkey's expiration time and date, and Algorithm specifies its public key algorithm:

Error Handling (C++)
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
