All Implemented Interfaces:

KeyStore.ProtectionParameter, Destroyable
```
public class ShamirsProtection
extends Object
implements KeyStore.ProtectionParameter, Destroyable
```
Protects a KeyStore instance and its entries by applying Shamirs Secret Sharing algorithm. Passwords have been splitted into several secret shares and have to been merged again to recover the original password. In order to create a ShamirsProtection instance someone has to provide access to a certain subset of secret shares, e.g. paths to different slices (JSON files) of shares.
