Password Obscuring Technique

Hi,
We have a unix shell script which tries login to database. The user name and password to connect to database is stored in a file connection.sql.

Now connection.sql has contents
Code:
def ora_user =&1

CONNECT A_PROXY[&ora_user]/abc123@DEV01

When on UNIX server we connect to database and set spool on and invoke connection.sql .. in the output spooled file we see the password. We want the password to be in encrypted form .. how can we achieve that?
Code:
SQL> set echo on
SQL> set feed on
SQL> set termout on
SQL> set sqlblanklines on
SQL> @GTBIR_DW/dbscripts/connection.sql BIR
SQL> def ora_user =&1
SQL> 
SQL> CONNECT A_PROXY[&ora_user]/abc123@DEV01
Connected.

SQL> spool off

In the spooled file we want something like this instead of displaying the password.
Code:
SQL> CONNECT A_PROXY[&ora_user]/******@DEV01

Thanks,
GR

mysql_drop_db - Drop (delete) a MySQL database

SYNOPSIS
Warning This function was deprecated in PHP 4.3.0, and will be removed in the future, along with the entirety of the original MySQL exten- sion. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include: oExecute a DROP DATABASE query bool mysql_drop_db (string $database_name, [resource $link_identifier = NULL]) DESCRIPTION
mysql_drop_db(3) attempts to drop (remove) an entire database from the server associated with the specified link identifier. This function is deprecated, it is preferable to use mysql_query(3) to issue an sql DROP DATABASE statement instead. o $database_name - The name of the database that will be deleted. o $ link_identifier -The MySQL connection. If the link identifier is not specified, the last link opened by mysql_connect(3) is assumed. If no such link is found, it will try to create one as if mysql_connect(3) was called with no arguments. If no connection is found or established, an E_WARNING level error is generated. Returns TRUE on success or FALSE on failure. Example #1 mysql_drop_db(3) alternative example <?php $link = mysql_connect('localhost', 'mysql_user', 'mysql_password'); if (!$link) { die('Could not connect: ' . mysql_error()); } $sql = 'DROP DATABASE my_db'; if (mysql_query($sql, $link)) { echo "Database my_db was successfully dropped "; } else { echo 'Error dropping database: ' . mysql_error() . " "; } ?> Warning This function will not be available if the MySQL extension was built against a MySQL 4.x client library. Note For backward compatibility, the following deprecated alias may be used: mysql_dropdb(3) mysql_query(3). PHP Documentation Group MYSQL_DROP_DB(3)
