[solved] hardnested attack ok ... but how to gathering keys for dump ?

Hello

I have a little question about hardnested attack, I'm sorry if already reply before, but I didn'tt find any post in relation to my question.

I use "hf mf hardnested" with success, but even if I can get keys, I don't know how I can do for collect all keys as "hf mf nested" do it in a file, with the aim for making a dump of the card.

Unless I'm mistaken, I found lots of post but no one talk about gathering keys for dump.
Anyone can help me ?
Thanks

I'm away from the client at the moment, but you can create a key file with a text editor and keep adding the keys as you find them.  Then use "hf mf chk" to check the keys and create a file used for a dump.  You can look at the default_keys.dic file to see the format.

Or you can run hf mf chk or another command that generates an incomplete dump file and use a hex editor to add the found keys in the correct place.

Thanks for your reply, I begin to understand, I didn' t see "hf mf chk" can make keys file with a dictionary file, I will make some test in this way.
otherwise, I always wonder what is the purpose of nonces file ? we create for first time command and we reuse after ?

off topic : A idea for hardnested command, why don't use sector instead block for Attack ?
Because you have one password by sector, you have to know which block belong to sector... not very convenient
Put a sector in command could be replace by one of 4 bloc which it belongs, no ?
(example : sector 1 will be block0, sector 7 will be block 28, sector 12 will be block 48, etc...)

This was from the time when hf mf hardnested took much longer (hours). You would have written the nonces file in a few seconds. Once you had the nonces file you could run hardnested without the card no matter how long it took. This is not necessarily required today.
