I wanted to make a challenge to do the full DES encryption algorithm, but that may be a bit too involved to get a ton of participation. This challenge is to simply generate the 16 48-bit subkeys used to encrypt data:
Your task is to write a program or function that accepts 64 bits of input, and outputs the 16 48-bit keys. I am not picky about input or output formats, but hex coded is fairly standard.
Shortest code wins.
