A CRC code is not a hash or a checksum, but a code: a transformation of a data word (the information you want to transmit) into a code word (the bit stream that gets sent over the wire). CRC cards are not actually a UML diagram, but are a useful tool to help in discovering the design that does get recorded in UML Interaction diagrams. This verification software has some useful features, but it is easy to understand and very easy to use.
