Class ModeReinitTest

java.lang.Object
  org.bouncycastle.util.test.SimpleTest
      org.bouncycastle.crypto.test.ModeReinitTest

All Implemented Interfaces:

Test

public class ModeReinitTest

extends SimpleTest

Re-initialisation of CBC and CFB with partial parameters: a key without an IV, an IV without a key, or null.

CBC and CFB differ here. CBC goes back to a zero IV when re-initialised without one, and cannot change direction without a key. CFB keeps the IV from its last init, and can change direction without a key, as its underlying cipher is only ever used to encrypt.

Expected values come from a reference built on the raw block cipher, not from the mode under test.
