I'm an old open-source independent hacker,

concerned about concepts of ethical hacking, teaching and sharing.

I like to play with shell, perl, lisp (sometime), sed and lot of other languages/environments.

Co-system administrator in several configurations, after various SMEs, I like to sometimes take time to focus on methods that I can improve or re-create (for example to change the level of abstraction).

In this, surfing on differents StackExchange's sites is a good way to boost my inspiration!

comment Why check to see if a password is already used by another user?
In fact, I did'nt read the PAM's man page: My question was more generic. In that, your second paragraph give a perfect answer! (And confirm my opinion;) Thanks!

comment Principle of asymmetric algorithm in plain english
I'm not ok with this: For closing a lock, there is no need of a key! While using a public key is using a key! Your analogy is more adapted to operation like umount and forgot masterkey of a encrypted filesystem.

comment Does changing the keyfile of a LUKS volume after opening it increase key security?
Wow, sorry not sure (now) about how the masterkey is protected. This may have to become another question! But for the use of the key, you are right. The key isn't used to decrypt datas and is securely driven to not stay in ram after use.

There is two opposed question between title and would it be possible to recover the volume masterkey... (My no answer to second question, not to title... Anyway... ;-)
