How to Encrypt password
Hello,

I have a paramter file, In which I store all the user-ids and passwords for the project. So if a user just invokes the paramter file he has access to all the variables, which i have exported in the parmatere file.

Now if a user echo's the variable which stores the databse password. He can clearly view it on the screen.

I define the password variable something like this.

Code:
var_pwd=pa$$worD
export var_pwd

So if I do

echo $var_pwd, It displays the password. I dont want this to be displayed as is, the output of echo should be some encryted text. How can i do this?

Thanks
DSDexter

nwvolinfo

NWVOLINFO(1)							     nwvolinfo							      NWVOLINFO(1)

NAME

       nwvolinfo - Diplay info on NetWare Volumes

SYNOPSIS

       nwvolinfo [ -h ] [ -S server ] [ -U user name ] [ -P password | -n ] [ -C ] [ -v volume ] [ -N ]

DESCRIPTION

       nwvolinfo displays information on a NetWare Server Volume.

       nwvolinfo  looks  up the file $HOME/.nwclient to find a file server, a user name and possibly a password. See nwclient(5) for more informa-
       tion. Please note that the access permissions of $HOME/.nwclient MUST be 600 for security reasons.

OPTIONS

       -h
	  -h is used to print out a short help text.

       -S server
	  server is the name of the server you want to use.

       -U user
	  user is the user name to use for login.

       -P password
	  password is the password to use for login. If neither -n nor -P are given, and the user has no open connection to the server,  nwvolinfo
	  prompts for a password.

       -n
	  -n should be given if no password is required for the login.

       -C
	  By default, passwords are converted to uppercase before they are sent to the server, because most servers require this. You can turn off
	  this conversion by -C.

       -v volume
	  The volume name to be used. Defaults to 'SYS'.

       -N
	  Display the information in numeric-only format for use in a pipe.
