Actually, I am using the Crypt-PasswdMD5-1.0 module which is dependant upon
the Digest::MD5 module. I'm just not sure how I'd go about creating a
password. Would this suffice:
#!/usr/bin/perl
my ($password) = shift;
my (@salt) = ('a..z','A..Z','0..9','.','/'); # Legal salt characters
# need a 12 character salt (according to Niall :)
$salt = int(rand(@salt)) . int(rand(@salt)) . int(rand(@salt)) .
int(rand(@salt)) . int(rand(@salt)) . int(rand(@salt)) .
int(rand(@salt)) . int(rand(@salt)) . int(rand(@salt)) .
int(rand(@salt)) . int(rand(@salt)) . int(rand(@salt)) ;
$cryptedpassword = unix_md5_crypt($password, $salt);
Creating the salt is what seems to be eluding me. Somewhere for a normal
DES/unix password I came up with this algorithm:
my (@salt) = ('a..z','A..Z','0..9','.','/'); # Legal salt characters
$salt = rand(@salt) . rand(@salt);
Which doesn't seem to make sense, since you want the salt to be a 2 character
string, and rand seems to be returning a float. Which, if appended together,
results in a mess.
Ironically, it seems to work. Also, according to the code in the
Crypt::PasswdMD5 module, the salt can only be 8 characters.
So, I guess at this point, I need to ask, How do I do this :)
