Key Property
The secret key for the symmetric algorithm.
Syntax
public byte [] getKey(); public void setKey(byte [] key);
Remarks
This secret key is used both for encryption and decryption. The secret key should be known only to the sender and the receiver. The legal key size varies depending on the algorithm.
If this property is left empty and KeyPassword is specified, a Key value will be generated by the bean as necessary.
