+     * the initialization vector, and then XORs those blocks with your stream
+     * blocks.  This means that an error in your stream will still produce an
+     * error in the output, but it will not propegate.  Also, with most
+     * encryption schemes error correction codes on the source data will still
+     * work on the encrypted data or decrypted output.
