Free password software for linux

Password Save extension brings up a plain text listing of your passwords in a browser window that can be easily copy-pasted or saved to the hard-drive.

Some javascript warning fixes and a bit of debugging code for helping people that the extension doesnt work for (Email me if you get a blank screen and have some free time to help me debug and well solve this problem once and for all)

In Preferences, go to Privacy => Passwords. When you click View Saved Passwords, there will be an added "Dump Passwords" button. Clicking this will pop up a new browser window with the saved passwords which can easily be saved, printed, or copy-pasted into another location.

This extension will only work (as is) on the released 1.5beta1 - 1.5beta2. The intall.rdf can be tweaked to get it to install fine on any recent nightly or the Deer Park Alphas. It -=can not=- be tweaked to work on 1.0. Sorry!

Ruby/Password is a suite of password handling methods for Ruby.
It supports the manual entry of passwords from the keyboard in both buffered and unbuffered modes, random password generation, password strength checking, phonemic password generation (for easy memorisation by human-beings) and the encryption of passwords.
CrackLib makes literally hundreds of tests to determine whether youve chosen a bad password.
- It tries to generate words from your username and GECOS entry and tries to match them against the password youve chosen.
- It checks for simplistic patterns.
- It then tries to reverse-engineer your password into a dictionary word, and searches for it in your dictionary.
- after all that, its PROBABLY a safe(-ish) password. 8-)
The target audience for this library is system administrators who need to write Ruby programs that prompt for, generate, verify and encrypt passwords.

ChangePassword modifies the passwords of passwd, Samba, and Squid through the Web. All passwords are syncronized and changed in real time through browsers like Mozilla, Netscape, IE, Opera, and others.

PasswordMaker project is a small, lightweight, free, extension for Internet Explorer, Firefox, Mozilla, Netscape, Flock, and Yahoo! Widgets which creates unique, secure passwords that are very easy for you to retrieve but no one else. Nothing is stored anywhere, anytime, so theres nothing to be hacked, lost, or stolen.

How It Works:
You provide PasswordMaker two pieces of information: a "master password" -- that one, single password you like -- and the URL of the website requiring a password. Through the magic of one-way hash algorithms, PasswordMaker calculates a message digest, also known as a digital fingerprint, which can be used as your password for the website.

Although one-way hash algorithms have a number of interesting characteristics, the one capitalized by PasswordMaker is that the resulting fingerprint (password) does "not reveal anything about the input that was used to generate it." In other words, if someone has one or more of your generated passwords, it is computationally infeasible for him to derive your master password or to calculate your other passwords. Computationally infeasible means even computers like this wont help!

Password Hasher enables a good security practice.
What good security practice demands:
- Strong passwords that are hard to guess.
- Different passwords at each site.
- Periodically changing existing passwords.
Why you probably arent practicing good security:
- Strong passwords are difficult to remember.
- Juggling a multitude of passwords is a pain.
- Updating passwords compounds the memorization problem.
Main features:
- Automatically generates strong passwords.
- One master key produces different passwords at many sites.
- Quickly upgrade passwords by "bumping" the site tag.
- Upgrade a master key without updating all sites at once.
- Supports different length passwords.
- Supports special requirements, such as digits and punctuation.
- Supports restricting a hash word to not use special characters. (New!)
- Saves all data to the browsers secure password database.
- Generates a portable HTML page with your site tags and option settings that allows you to generate your hash words in any browser on any machine without the extension installed. (New!)
- Can add marker buttons to unmask passwords on any web site. (New!)
- Extremely simple to use!

If you arent concerned about someone looking over your shoulder and stealing your passwords, why hassle with those obfuscated password fields, where you never know whether you typed your 30 character code correctly or not...

Unhide Passwords shows the contents of password fields in cleartext (instead of the asterisks), to make that process a bit easier.
