Using Keychain for storing archived object ?

Hello,

My application creates an object that is the result of NSKeyedArchiver
in NSData type.
Instead of saving this object in an unsafe external file (using [NSData
writeToFile ...] )
i thought to use KeyChain as a secured container such as :
   myObject -> archiver -> NSData -> store in keyChain
The object itself is small enough (4ko).

I tried some keyChain API - as a newbie - (such as
SecKeychainItemCreateFromContent or SecKeychainAddGenericPassword...),
i can create a keyChain item that (seems) contains my NSData, i can
retrieve the item and the data
but the NSKeyedUnarchiver operation on that data totally fails.

Can you tell me if storing NSData type via KeyChain is an available
solution ?
If not, what will be the best solution for my need ?

Thx a lot for you help,
K.
