RoutingKeyGenerator (I2P Anonymous Network - Java Documentation - Version 1.5.0)

java.lang.Object
- net.i2p.data.RoutingKeyGenerator

Direct Known Subclasses:

RouterKeyGenerator
```
public abstract class RoutingKeyGenerator
extends Object
```
Component to manage the munging of hashes into routing keys - given a hash, perform some consistent transformation against it and return the result. This transformation is fed by the current "mod data". As of 0.9.16, this is essentially just an interface. Implementation moved to net.i2p.data.router.RouterKeyGenerator. No generator is available in I2PAppContext; you must be in RouterContext.
