file transfers, keep in mind that UDP is not reliable. The lightweight UDP protocol shim does not admit much in the way of additional functionality, and one possible approach is to insist that UDP-based applications limit themselves to the local MTU size or, to be even more conservative, limit themselves to the 1,280 octet IPv6 minimum unfragmented packet size. • The UDP checksum is calculated on the sending and receiving side by summing all the 16-bit words in the segment, with any overflow being wrapped around and then the 1's complement is performed.

The point of signing the checksums instead of the file is that it's faster to verify, provides the same security/integrity guarantees, and you can have signed checksums for lots of different files and only one signature, instead of having a signature for each file. The number of exclamation points following varies from zero to five or so. The checksum field covers the UDP datagram header and data, as well as a 96-bit pseudo header that contains the IP header Source Address, Destination Address, and Protocol fields, as well as the UDP datagram length. This special TCP checksum algorithm was eventually also adopted for use by the User Datagram Protocol (UDP). The checksums within the UDP and TCP headers are computed in exactly the same way as the IP checksum.
