org.flasby.settings.Encrypt

All Implemented Interfaces:

Iterable<Map.Entry<String,String>>, Settings, SimpleSettings

Direct Known Subclasses:

MixedEncrypt

public class Encrypt
extends Object
implements SimpleSettings

encrypts all key value pairs when adding them as a setting. decrypting will generate a new Cipher instance for decryption as every encrypted value will likely have a different IV.
