TScFileStorage: supports CTR...or not?

[cboling]

The GUI (Object Inspector) shows a full complement of CTR & CBC cipher variants available for the "Algorithm" property of the TScFileStorage class. However, if you choose a CTR flavor, execution of the .Keys.Add method throws an exception:

This cipher algorithm is not supported

(behavior observed in 8.1.2 & 8.1.3)

All the algorithms supported by SecureBridge are listed in the TScFileStorage.Algorithm property. SecureBridge stores keys in the standard PKCS8 format that does not support all the algorithms.
