Class Salsa20StreamEncryptor

java.lang.Object

org.linguafranca.pwdb.kdbx.stream_3_1.Salsa20StreamEncryptor

All Implemented Interfaces:

StreamEncryptor

public class Salsa20StreamEncryptor
extends Object
implements StreamEncryptor

A helper class for Salsa20 encryption.

Salsa20 doesn't quite fit the memory model supposed by SerializableDatabase.StreamEncryptor - all encrypted items have to be en/decrypted in order of encryption, i.e. in document order and at the same time.

The encrypt and decrypt methods actually do the same thing. They are here only to fulfill the interface contract.
