org.apache.xml.security.encryption.XMLCipher.decryptToByteArray()
Decrypt an EncryptedData element to a byte array. When passed in an EncryptedData node, returns the decryption as a byte array. Does not modify the source document. @param element @return the bytes resulting from the decryption @throws XMLEncryptionException
