MetaSeedGenerator ("Entrust Authority Security Toolkit for the Java Platform")

Deprecated.
since 8.0; seeding is now handled automatically by Entrust's SecureRandom implementations (random number generators); for access to the PRNGs underlying seeding algorithm call generateSeed() on the SecureRandom instance.
```
public class MetaSeedGenerator
extends SeedGenerator
```
This seed generator generates new seeds given an initial seed. Often an application will need a number of seed generators. There is no need to seed each one separately from e.g. new user events, it is secure to generate a random seed only once and deduct further seeds from it using deterministic methods. This is what this class is for, it internally uses the system's default PRNG. The JDK SecureRandom uses a very similar mechanism.
To use it, first set the initial seed via one of the static setSeed() methods. Then create as many instances as you like using the constructors. It is anticipated that this seed generator will often be used as the default seed generator following an initialisation from user input.
NOTE: For obvious reasons, the initial seed should be as least as long as the longest seed that later is to be deducted from it. Also, as this classes uses the system's default PRNG (usually SHA1Random), so it can never generate true random seeds longer than the PRNG digest (160 bits for SHA1Random).
