Examples of org.keyczar.Encrypter

org.keyczar.Encrypter
Encrypters are used strictly to encrypt data. Typically, Encrypters will read sets of public keys, although may also be instantiated with sets of symmetric keys. {@link Crypter} objects should be used with symmetric or private key sets todecrypt data. @author steveweis@gmail.com (Steve Weis)
