Unrelated to hashes, but from <a href="https:&#x2F;&#x2F;www.ietf.org&#x2F;archive&#x2F;id&#x2F;draft-kaduk-afs3-rxkad-k5-kdf-00.txt" rel="nofollow">https:&#x2F;&#x2F;www.ietf.org&#x2F;archive&#x2F;id&#x2F;draft-kaduk-afs3-rxkad-k5-kd...</a> :<p>&quot;Although administrative access to the cell still uses single-DES for encryption of network traffic, that single-DES key is time limited and may be resistant to brute-force key recovery prior to its expiration.&quot;<p>This wasn&#x27;t created until after CloudCracker can break DES, but to be honest OpenAFS is not the only one either. DOCSIS I think do something similar too. I wonder if anyone has created ASICs to break DES.
