The workings of the algorithm are explained: http://www.tropsoft.com/strongenc/des.htm and the official page at the [NIST]: http://www.itl.nist.gov/fipspubs/fip46-2.htm
[DES] is to be replaced with [AES], it's successor.
-[DES] was designed by people at [IBM] with help from the [NSA]. A lot of controversy about how the [NSA] had placed a back door/flaw in [DES] so they could decrypt all messages that were encrypted with [DES].
After about 30 years of [DES] being used a new attack on ciphers was found which almost all ciphers at the time fell to, except
[DES]. It is believed that the [NSA] probably knew about this attack (30 years before everyone else!) and "fixed" [DES] so that it was safe against it. Anyway, take this little story with a grain of salt, and put on your tin foil hat next time you're outdoors.
+The "Standard" part of the name is because DES is/was the algorithm used by many US government agencies, and therefore also by many companies.
