AddLegalKeySize	Adds a new KeySizes object with the supplied values to the list of legal key sizes.
Clear	Clears the IV and Key values.
CloneRgbIV	Returns a clone of an IV.
CloneRgbKey	Returns a clone of a key.
GenerateIV	Generates a random IV value.
GenerateKey	Generates a new random key.
GetIV	Returns the current IV value.
GetKey	Returns the current secret key.
SetIV	Sets the current IV value.

Events:

Name	Description
CheckForWeakKey	Used for implementations that must check for some kind of weak or semi-weak key.

Remarks

The base class implements many of the details necessary for implementing a Symmetric Cryptographic Algorithm. By utilizing the base class the implementor can quickly provide a new implementation that is consistent with the existing implementations without the need to manage lower level details.
