net.i2p.crypto.CryptixAESKeyCache
public final class CryptixAESKeyCacheextends Object
Cache the objects used in CryptixRijndael_Algorithm.makeKey to reduce memory churn. The KeyCacheEntry should be held onto as long as the data referenced in it is needed (which often is only one or two lines of code)

Not for external use, not a public API.

Unused as a class, as the keys are cached in the SessionKey objects, but the static methods are used in FortunaStandalone.

  • Constructor Details

      public CryptixAESKeyCache()
      Constructor. The round-key cache itself is never instantiated - entries come from the static createNew() - so a bare instance holds nothing.
