What puzzles me is that he included two cyphers that are _extremely_ easy to break, the vignere cypher and the ascii cypher. Why include these? And what is his new permutation of RC4 and DES? The reason I included ASCII and Vigenere was because they are very fast; on a friend's machine, I can get 1.7mb/s with ASCII but only around 600k/s with NewDES, the fastest "secure" cipher. I do agree that it is kind of redundant to include both ASCII and Vigenere, as from a cracking standpoint, they are both identical. As for Psuedo-RC4, that is just to try to avoid a lawsuit from RSADSI; RC4 is a trademark. NewDES is an actual algorithm; it's even mentioned in Applied Cryptography. It does have some holes and is in fact less secure than DES (refer to Applied Cryptography for details on this); I included that because it is fast and provides much, much more security than ASCII or Vigenere, even if it is less secure than DES.
