Encryption does not work that way.

But what if --

Encryption does not work that way.

Maybe if it --

Encryption does not work that way.

To prevent people from reading your scripts/passwords, chmod.

To prevent people getting access to something which reads the scripts/passwords, sudo.

To prevent root from getting at it... You're out of luck.

This question fools everyone eventually... I spent a long while earlier this year down a rabbithole trying to find a way to make arbitrary apache suexec secure, until I realized I was fighting what amounts to the same problem -- how to prove identity to the computer without using secrets.

NAME
script-email - Amanda script to send email notifications DESCRIPTION
script-email is an Amanda script implementing the Script API. It should not be run by users directly. It sends a notification email to the addresses specified in the MAILTO property. PROPERTIES
This section lists the properties that control script-email's functionality. See amanda-scripts(7) for information on the Script API, script configuration. MAILTO List of email addresses that will receive an email on command execution. It is a multi-valued property: property "MAILTO" "amanda@domain.com" "sysadmin@domain.com" "amandauser@domain.com" EXAMPLE
In this example, script-email is scheduled to be run before the DLE, on the server. The unqualified email address amanda will be passed to the email system unchanged. The script is then attached to a dumptype, which can then be specified for any DLEs which require notification. define script-tool pre-email { comment "email me before this DLE is backed up" plugin "script-email" execute-on pre-dle-backup execute-where server property "mailto" "amanda" } define dumptype user-tar-email { user-tar script "pre-email" } SEE ALSO
