[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]

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

public abstract void GenerateKey()

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.
