Title Data Encryption Standard (64-bit)
Description This program performs the forward and reverse encryption of the DES algorithm. It's not particularly useful for actual encryption since it takes a long time (~5 minutes per 64 bits), but it demonstrates the ability of the TI-83/84+ family of being able to perform these complex algorithms using the TI-Basic language. I did my best to optimize for both speed and memory. It's probably not perfect, but it should be pretty darn close. More information on the algorithm can be found here: https://en.wikipedia.org/wiki/Data_Encryption_Standard
