That's not salt. "Since DES only encrypts in blocks of 64 bits (8 bytes) then encrypting and keeping the length of blocks means that you actually get a very good idea of the length of the password - that is, anything with only one block is a password length between 1 and 8 characters, with two blocks between 9 and 16 characters etc. In addition a password of "1234567812345678" would encrypt into two identical blocks." http://www.explainxkcd.com/wiki/index.php?title=1286 |
