Post: iClass request

Some ppl has been asking about this and my own curiousity has been there since I implemented a naive dictionary implentation for the proxmark3 client. There are different attacks already for differen...

This competition sounds like something @atom et al should have some fun solving ;) Or anyone else of course. AES, ECB, http://scienceblogs.de/klausis-krypto-kolumne/2016/10/06/the-world-record-...

Yes, I did notice that Hashcat went open source. But I'm curious, how does the KDF for descrypt look like? I mean algorithmwise.

Post: RE: TEA/XTEA imp

In the system Im looking at, the assumption is that TEA is used as a KDF. We call it a pwdgen pwd = tea(Secret key, unique bytes) btw doesn't hashcat support DES and other cryptos?...

Post: RE: TEA/XTEA imp

Indeed it is a block cipher, with 128bit key, which works on 64bit blocks. Given one scenario where its not used for streams (memory, files), but only one block, to find the key then the differe...

Post: RE: des / 3des question

IN the proxmark3 community dealing with rfid sec, we usually have very small messages. Like 8bytes, which could be seen as a hash. Not so often they use a salt to a masterkey, but they do mix it ...

Hi, I understand that Hashcat is a tool for solving hashes, really fast by the looks of it. And I'm into RFID security, where I get to deal with the underlying crypto-algos. At the moment three ...
