Class UsageStatistics.CombinedCipherOutputStream

java.lang.Object

java.io.OutputStream

java.io.FilterOutputStream

hudson.model.UsageStatistics.CombinedCipherOutputStream

All Implemented Interfaces:

Closeable, Flushable, AutoCloseable

Enclosing class:

UsageStatistics

public static final class UsageStatistics.CombinedCipherOutputStream
extends FilterOutputStream

Asymmetric cipher is slow and in case of Sun RSA implementation it can only encrypt the first block. So first create a symmetric key, then place this key in the beginning of the stream by encrypting it with the asymmetric cipher. The rest of the stream will be encrypted by a symmetric cipher.
