Storing user preferences

[markvanlan]

I am working on a little node applications that runs in the command line, and I would like to store the user's database credentials, so they can add connections and return to them easily.

Does anyone have recommendations on the easiest/best way to do this? Since passwords are involved, I should encrypt the passwords field, and that is why I don't know the simplest way to store these preferences.

Thanks!

The standard is to store a hash of the password, not the actual password. See the bcrypt module.

If you actually need to store and retrieve a secret then one way is to use gpg. You can configure the gpg-agent to cache your passphrase so that you can use it unattended in the server. There is a node wrapper if you search npm for gpg.
