Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.

When overridden in a derived class, generates a random key (Key) to use for the algorithm.

C# 
public abstract void GenerateKey();

Remarks

In general, there is no reason to use this method, because CreateEncryptor() or CreateEncryptor(null, null) automatically generates both an initialization vector and a key. However, you may want to use the GenerateKey method to reuse a symmetric algorithm instance with a different key.
