MD5 BSD like passwords

[Felipe Cruxen]

I'm coding a "postfixadmin" using ruby, so, all the passwords are stored
in DB using a bsd like md5 hash. Is there any simple way I could
generate passwords like that (the same hash could be used to generate
shadow pass?)?.

Really sorry for my lame english, and if the question is stupid, but I'm
a real newbie to ruby.

Thanks in advance.

you can generate MD5 with:
require 'digest/md5'
hash = Digest::MD5.digest(data) # binary
or hash = Digest::MD5.hexdigest(data) #hexa

If that's really a BSD-like password (in the form $n$aaaaaaa$aa...), the
crypt function should be able to generate it on a unix system, as long
as you pass the entire salt ($ included) :
=> "$1$Eou1PtvJ$bh2HAitLkEOwoU6Fjuh8i0"

If you take a look at the manpage of the crypt system function (man 3
crypt or http://www.freebsd.org/cgi/man.cgi?query=crypt&sektion=3 ),
you'll see an explanation of the hash format.

I have no idea of the portability of that function, though. For
instance, it doesn't work on my Windows box, but it works well enough
with FreeBSD and Linux.

Thanks a bunch for the reply. I'll take a good look at the documents.
