Store information on security place

Question

Hello All,
I'm using some dbms_crypto for encypt/decrypt data with following code:
create or replace FUNCTION sec_return_encrypted_data(data IN VARCHAR) RETURN RAW IS
    key VARCHAR(16) := 'A1B2C3D4E5F6G7H8';
    encryption_mode NUMBER := DBMS_CRYPTO.ENCRYPT_AES128 + DBMS_CRYPTO.CHAIN_CBC  + DBMS_CRYPTO.PAD_PKCS5;
    BEGIN           
         RETURN DBMS_CRYPTO.ENCRYPT(UTL_I18N.STRING_TO_RAW (data, 'AL32UTF8'),
           encryption_mode, UTL_I18N.STRING_TO_RAW(key, 'AL32UTF8') );
    END;
There is some variable, which is key. I need to store it some security place. How and where to store?
Because it not visible for developers.
Any idea and solution?
BR,
Eba

If you know what browser cookies are, you can think of flash player local storage as the same sort of thing. That is, some storage space on your computer where a website can store information until it needs it, milliseconds or weeks later. As with cookies (or pretty much any tool), flash local storage can be used for helpful or harmful purposes.
Because there are people in the world who use flash local storage for harmful purposes (as they were already using cookies), and because flash local storage is more difficult for people to find and remove, Safari now asks you for permission before it allows a website to use it. This is the message you are seeing.
As for how to get rid of the message, there are several possibilities, depending on what you want Safari to do instead of asking. You could just turn off Flash entirely, but then you may lose some web content you want. You can install a flash-blocker like ClickToFlash, which allows you to choose which Flash content you want to see, but you may still see that message with flash content you choose to display.
I run a flash blocker, so I cannot advise you on what to do if you choose to leave Flash unblocked. There are probabably ways to set a default "allow" or "disallow"; I leave that discussion to others.
