Key Property
The secret key for the symmetric algorithm.
Syntax
ANSI (Cross Platform) int GetKey(char* &lpKey, int &lenKey);
int SetKey(const char* lpKey, int lenKey); Unicode (Windows) INT GetKey(LPSTR &lpKey, INT &lenKey);
INT SetKey(LPCSTR lpKey, INT lenKey);
@property (nonatomic,readwrite,assign,getter=key,setter=setKey:) NSString* key; - (NSString*)key; - (void)setKey:(NSString*)newKey;
@property (nonatomic,readwrite,assign,getter=keyB,setter=setKeyB:) NSData* keyB; - (NSData*)keyB; - (void)setKeyB:(NSData*)newKey;

Default Value
""
Remarks
This secret key is used both for encryption and decryption. The secret key should be known only to the sender and the receiver. This key must be 256 bits in length (32 bytes).
If this property is left empty and KeyPassword is specified, a Key value will be generated by the class as necessary.
