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!

@D3C4FF Yes, of course as there is no external requirement, all this would be better done offline. (In fact the host I use to do this is not configured with a default route)

comment Writing file shredder
Nice exploration of what's about! Just: In order to install a decoy, you have to: .1 shred all blocks, .2 fill all block with 0 (0x00) and finaly .3 install a fake. For ensuring not to leave suspect random data in the last block!

comment Could I delete .csr files when the key is signed by CA
+1, thank for explaining step by step! ( I only build client key on CA for special case where the client is a thin embed, built by scripts of mine by the same securised CA host... And the CA's disk is backuped on remote host, but encrypted.)
