Two RC2ParameterSpec objects are considered equal if their 0N/A * effective key sizes and IVs are equal. 0N/A * (Two IV references are considered equal if both are <tt>null</tt>.) 0N/A * @param obj the object to test for equality with this object. 0N/A * @return true if the objects are considered equal, false if 0N/A * <code>obj</code> is null or otherwise. 0N/A * Calculates a hash code value for the object. 0N/A * Objects that are equal will also have the same hashcode.
