I would like to use Ubuntu's start-stop-daemon
to start my application, but the application protects some sensitive information, so I have a mechanism where the application prompts for a password that's then used to generate a hashkey, which is used as the secret key for a symmetric encryption (AES) to encrypt and decrypt things from a database.
I'd like to daemonize this application and have it run from start-stop-daemon
, so that sudo service appname stop
and sudo service appname start
would work, but, I'm not sure how to go about doing this with the added complexity of a password prompt.
Is there something that supports this or do I have to program it from scratch? I figured I should ask first before re-inventing the wheel.
Thanks in advance.
It should fail if not prompted. So, it doesn't necessarily have to conform to the definition of a 'true daemon.' Can you elaborate a bit more on what you mean by a major re-architecture? I haven't coded anything, but according to a compliance specification that I'm reading, prompting for a master key is considered an acceptable security measure for generating the symmetric key to decrypt/encrypt. – Mahmoud Abdelkader – 2011-01-12T00:56:34.987
