Hi,

I've been using Password Safe on Windows for all my passwords but I want to move them over to my gentoo box. So how do I store them safely?

I was thinking about keeping them in a text file encrypted with gpg (symmetric) and to fetch the entry I want with something like the following:

Code:
gpg -d pw.gpg | grep "Entry"


As a side note is it easy for someone who knows what he/she is doing to see what I had on my clipboard after I've replaced it with something else? (I'm not using Klipper). And the same goes for my konsole after I've closed it?

The only safe way to keep passwords is to never write them down. Keep them in your head. As of yet, no one can hack that 8O

Of course, that would be the ideal solution, but i have more than 100 passwords in Password Safe for different sites, services and servers. Hard to keep in your head don't you agree?

( Please don't tell me to use the same password for all :wink: )

The same, no but you might differentiate by security level and use the same password for the same security level, reducing notably the amount of strings to remember.

I'm not in a position to change all the passwords and they are not all set by me in the first place. Someone must be in the same position? I mean if there is a market for products like Password Safe on Windows, there must exist a market on Linux considering all the servers out there.

I'm going to go on a rant here (I apologize in advance). I believe there is a market for password saving applications because the average user is so grossly ignorant of computer security that they only see passwords as an inconvenience.

How many times have you seen users write passwords on post-it notes on their monitors? Users often share passwords with each other. I often see users leave their computers unattended and unlocked for long periods of time. Users often pick passwords that are rediculously easy to crack.

You are warned against having the same password for many services yet, storing different passwords in one location defeats the purpose of having different passwords. To retrieve all of your passwords I only need crack one.

If I ask you how to drive a car, would you tell me to ride a bike? :roll:


First of all I love passwords, I don't see them as an inconvenience.
At my previous job the network administrator used Password Safe because he had to keep track of a bunch of passwords, so I'm not the only one.

Users who write down their passwords on post-it notes doesn't use applications like Password Safe, atleast not among the people I know.

If I only have to remember 1 password I can select one that is almost impossible to break with brute-force.

Yes they do. Email clients can retain your passwords. Web browsers can retain passwords for websites.

As for your question. I would suggest you use GnuPG to encrypt your password text file. Just make sure the password is very good.

I use gringotts to store passwords as well as various other sensitive information. It's nice, simple and flexible :)

I have to agree w/ aeris. For many people, choosing a common password for sites/services that have teh same security clearance is not an option.

Or should I go and tell all of my customers to please change their administrator passwords so it would be much easier for me to remember? No.. Why not? Because I would get fired faster than Gentoo boots...(And that is pretty quick, atleast for my system) :D
So, a powerful software to keep order and security amongst the passwords is most wanted for many..

Someone who reads this forum must atleast have some experience with a good program?

How does Admins at larger companies handle this?

I'm using GnuPG for storing passwds. I don't have the same password for all resources I use, but each time I create a password it is something like
Code:

DRE(#$7RjcxSL:AWE_)$&@#,CX>;AAW

and so on. Which is pretty hard to keep in your head, especially when you have hundreds of those. GnuPG makes my life easier.

Not linux-based, but I use STRIP on my Visor -- it's incredibly useful when we sysadmins change passwords, because then we can just beam each other the encrypted passwordset, and *boom*, it's all synced!

By definition brute-force means trying *every* combination until it is broken. You cannot pick a password that cannot be brute-forced. You *can* pick a password that will take some time, but if the length of the password is known that drastically reduces the amount of time needed to break it.

Almost impossible, almost.. not impossible. Did you really think that post was necessary?

I agree with aeris that there is a need for applications like he asked about.

There is a lot of systems that can not even use the same password, restrictions on lenght, contents, mix of numbers and letters and special characters etc.

Plus the fact that some people need to have access to passwords used by several. How about this:
You are in charge of the IT department of a small to medium sized business. The sysadmin with the root password got killed in a car accident. How do you get into the server to change it? By having a central repository for system passwords in an organization you can ensure that the systems are accessible and that your business continues to run without a hitch even if some key personell is no longer with you.

Yes, aeris, a very valid question IMHO.

(Oh and let us know what you find and you experience with it)

Figaro's password manager also works well, theres no ebuild and it requires gnome libraries.

I have written an ebuild, here:

http://bugs.gentoo.org/show_bug.cgi?id=18684

I have been using FPM for ages -- it is a mature, functional piece of software. Unfortunately, it is a GNOME1 app, so it presents some minor annoyances in my GNOME2 environment (not the least of which is that it looks rather ugly). Development seems to have stalled, and I did not get replies to the one or two emails I sent to the author.

I will give Gringotts a try.

The good thing about using a tool on a Palm is that it adds a level of physical security if the Palm data is not kept on a networked device.

To my way of thinking, if the password you use for the password manager is harder to crack than any other password, then security is not compromised to the degree it would be otherwise. It is true that cracking the pw manager password provides all passwords; however, to do so, a cracker would need to crack the hardest password.

Don't listen to all this hype ;);)
Use gpasman or kpasman (in portage), or the already mentioned gringotts (<= really good!)

That's what I do.

One of my concerns is trusting my passwords to a proprietary (non-text) format -- if one of these password safes chooses to screw up at an inopportune time, my passwords might be lost. So instead:

For 99% of protected content, I use a homegrown utility to generate a random password based on the site's requirements (no symbols, alphanumeric only, numbers only, etc.), and I keep those passwords (about 150 so far) in a plain text file which I keep encrypted using asymmetric encryption through GnuPG.

On my personal workstation, I decrypt the file to a tab in Gnome Terminal, and then just leave this tab open until a reboot. This keeps the file secure at all times, and the passwords are only cached in RAM. The way I see it, if someone broke into my apartment, broke into my room, then knew my screen saver password (which is not in any file), then they must be me.

Furthermore, because I use asymmetric encryption for this file, only my workstation (and another copy of the encryption key which I keep physically locked up) can decrypt the file. I've been using this system for about two years now, and have peace of mind.

I use a three part password. Part is based on the year I started using the service, part is based on an extremely simple mental hash of the service's name, and the other part is base on standard set of symbols for the /type/ of service (I have about 10 different ones of those)

It's a very convenient system -- differenet, strong passwords for everything and very easy to keep track of without writing or storing them down anywhere.

I use Password Gorilla. I keep Linux and Windows binaries (no install required), along with the encrypted password file on a USB flash drive. While there are some questionable claims on the website (e.g. "It is not possible to break into a password database without knowing the master password.") this does a reasonable job of ensuring privacy.
