- * The implementation of the Trailing Bit Complement (TBC) padding algorithm.
- * <p>
- * In this mode, "...the data string is padded at the trailing end with the
- * complement of the trailing bit of the unpadded message: if the trailing bit
- * is <tt>1</tt>, then <tt>0</tt> bits are appended, and if the trailing
- * bit is <tt>0</tt>, then <tt>1</tt> bits are appended. As few bits are
- * added as are necessary to meet the formatting size requirement."
