KeyDerivationMethod (Apache XML Security for Java 4.0.2 API)

All Known Implementing Classes:

KeyDerivationMethodImpl
```
public interface KeyDerivationMethod
```
The key derivation is to generate new cryptographic key material from existing key material such as the shared secret and any other (private or public) information. The purpose of the key derivation is an extension of a given but limited set of original key materials and to limit the use (exposure) of such key material. The Schema for KeyDerivationMethod is as follows:
