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!

In the other way, with virtualization like openVz you may have many differents hosts after only one mac address.

comment Computing entropy for a passphrase ( minimal word length … )
In fine, I've followed your recommendation to set default random generator to /dev/urandom, but I've added an option to let user ability to choose another way genpassphrase.pl -d wl_15bits.lst -r <(echo -ne '\001\002\003\004\005\006\007\010\011\012').

comment Computing entropy for a passphrase ( minimal word length … )
While I could use this to generate sometime (no more than 10 per a day) one passphrase, with the need of only 10 bytes, is there a good reason to not use /dev/random and to prefer /dev/urandom ??

No, I'm pretty sure in my second sample, using 450bits to humanly choose 5 words would drop entropy down under 75bit in fine. This seem paradoxal, but... There must exist a mathematical demonstration.

This seem UTF8 or UTF16 viewed in Ascii console. There miss some values replaced there by an interrogation point: . Decoding this not possible in this state. we need original raw dumper in hex maybe.

@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)

You could easily get the source code and take a look, GnuPG is open-source!
