Class EncryptOutputStream

java.lang.Object
java.io.OutputStream
java.io.FilterOutputStream
oracle.security.xmlsec.enc.EncryptOutputStream

All Implemented Interfaces:

java.io.Closeable, java.io.Flushable

public class EncryptOutputStream

extends java.io.FilterOutputStream

This class is similar to the CipherOutputStream, except that it does two special things to conform to XML encryption, a) it emits the IntializationVector at the beginning of the stream and b) it emits a padding at the end of the stream .
Note: the cipher object must be set up for NoPadding, or for ISO10126Padding
If you are using a nonce, you must write the nonce into the EncryptOutputStream in the beginning, that way it will get encrypted.
