Random password generation

Hello,

I have created a script to generate a random password on Linux/Solaris, but I simply cannot use it on my AIX VMs since Bash isn't installed on them.

I need a password that is randomly created with the following characters:
Code:
0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ!@;:[].{}+=<>#|()^&_0123456789

And that's where the problem is.. those special characters are excluded from commands such as makekey.

Here's what I've done for Linux:
Code:
MATRICE="0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ!@;:[].{}+=<>#|()^&_0123456789"
n=1
PASSWD=""
while [ "$n" -le 7]
do
  PASSWD="$PASSWD${MATRICE:$(($RANDOM%${#MATRICE})):1}"
  let n+=1
done

Any ideas how I can generate a random password that doesn't require bash installed, and that takes into account all the special characters?

Thanks!

PASSWD.NNTP(5)							File Formats Manual						    PASSWD.NNTP(5)

NAME
passwd.nntp - passwords for connecting to remote NNTP servers DESCRIPTION
The file /etc/news/passwd.nntp contains host-name-password triplets for use when authenticating client programs to NNTP servers. This file is normally interpreted by the NNTPsendpassword routine in libinn(3). Blank lines and lines beginning with a number sign (``#'') are ignored. All other lines should consist of three or four fields separated by colons: host:name:password host:name:password:style The first field is the name of a host, and is matched in a case-insensitive manner. The second field is a user name, and the third is a password. The optional fourth field specifies the type of authentication to use. The default is ``authinfo'' which means that NNTP ``authinfo'' commands are used to authenticate to the remote host. If either the username or password are empty, then the related command will not be sent. (The ``authinfo'' command is a common extension to RFC 977.) For example: ## UUNET needs a password, MIT doesn't. mit.edu:bbn::authinfo uunet.uu.net:bbn:yoyoma:authinfo This file should not be world-readable. HISTORY
