IV Property
The initialization vector (IV).
Syntax
ANSI (Cross Platform) int GetIV(char* &lpIV, int &lenIV);
int SetIV(const char* lpIV, int lenIV); Unicode (Windows) INT GetIV(LPSTR &lpIV, INT &lenIV);
INT SetIV(LPCSTR lpIV, INT lenIV);
@property (nonatomic,readwrite,assign,getter=IV,setter=setIV:) NSString* IV; - (NSString*)IV; - (void)setIV:(NSString*)newIV;
@property (nonatomic,readwrite,assign,getter=IVB,setter=setIVB:) NSData* IVB; - (NSData*)IVB; - (void)setIVB:(NSData*)newIV;
#define PID_EZCRYPT_IV 5 IPWORKSENCRYPT_EXTERNAL void* IPWORKSENCRYPT_CALL IPWorksEncrypt_EzCrypt_Get(void *lpObj, int propid, int arridx, int *lpcbVal, int64 *lpllVal); IPWORKSENCRYPT_EXTERNAL int IPWORKSENCRYPT_CALL IPWorksEncrypt_EzCrypt_Set(void *lpObj, int propid, int arridx, const void *val, int cbVal);
Default Value
""
Remarks
This property specifies the initialization vector (IV). By default this property is empty and the class will automatically generate a new IV value if KeyPassword or Key is set before Encrypt or EncryptBlock is called. The size of the IV property must be equal to the BlockSize divided by 8.
