Not knowing your environment here we go:
Why does the password variable has to be exported? Can't they just enter the password at a prompt/command when connecting to the DB?
Aren't they already authenticated when being logged in with their personal account on the Linux/Unix box?
You could write an script that manages passwords and environments where the passwords are crypted via md5sum and stored or something.
Could someone please help me...I have an expect script. There's a need for a log in during the script and a password is required...right now the password is just a variable in the expect script...what would be the best way to put that in an encrypted flat file and have the expect script pull the...

pwhash
PWHASH(1) BSD General Commands Manual PWHASH(1)NAME
pwhash -- hashes passwords from the command line or standard input
SYNOPSIS
pwhash [-km] [-b rounds] [-S rounds] [-s salt] [-p | string]
DESCRIPTION
pwhash prints the encrypted form of string to the standard output. This is mostly useful for encrypting passwords from within scripts.
The options are as follows:
-b rounds
Encrypt the string using Blowfish hashing with the specified rounds.
-k Run in makekey(8) compatible mode. A single combined key (eight chars) and salt (two chars) with no intermediate space are read from
standard input and the DES encrypted result is written to standard output without a terminating newline.
-m Encrypt the string using MD5.
-p Prompt for a single string with echo turned off.
-S rounds
Encrypt the salt with HMAC-SHA1 using the password as key and the specified rounds as a hint for the number of iterations.
-s salt
Encrypt the string using DES, with the specified salt.
If no string is specified, pwhash reads one string per line from standard input, encrypting each one with the chosen algorithm from above.
In the event that no specific algorithm is given as a command line option, the algorithm specified in the default class in /etc/passwd.conf
will be used.
For MD5 and Blowfish a new random salt is automatically generated for each password.
Specifying the string on the command line should be discouraged; using the standard input is more secure.
