    I'm not too sure whether this is the right forum to ask this but I 
    couldn't find a Crypto mailing list so here goes: 
    
    I have a few questions on the DES Encryption algorithm:
    
    1. In DES algorithm, given an encrypted text and the corresponding plain 
    text for that is it possible to retrieve the key. Essentially, how secure 
    is DES to known-plain text attack. I read some where that it is quite 
    resistant requiring 2^55 plain texts to get the key but why is this so? 
    What particular feature of the algorithm makes it this way?
