Free safe software for linux

Safe::World can create multiple virtual instances of a Perl interpreter that can be assembled together.

SYNOPSIS

See USE section for complexer example and the test.pl script.

use Safe::World ;

my $world = Safe::World->new(
stdout => $stdout , ## - redirect STDOUT to this scalar.
stderr => $stderr , ## - redirect STDERR to this scalar.
flush => 1 , ## - output is flushed, soo dont need to wait exit to
## have all the data inside $stdout.
) ;

## Evaluate some code:
$world->eval(q`
use Data::Dumper ;
print Dumper( {a => 1 , b => 2} ) ;
`);

$world->close ; ## ensure that everything is finished and flushed.

die($stderr) if $stderr ;

print $stdout ;

$world = undef ; ## Destroy the world. Here the compartment is cleanned.

Note that in this example, inside the World is loaded Data::Dumper, but Data::Dumper was loaded only inside of it, keeping the outside normal.

Kid-Safe LiveCD is the perfect way for young children to learn about computers.
First, since the entire system runs off of a read-only CD-ROM, parents can let their childeren play on the computer without having to worry about their primary desktop being altered or damaged.
Also, this CD has a content filtering system installed to keep your kids safe on the internet. The filters are setup for a target audience of pre-school and elementary school children. Even so, you should still monitor your child while on the internet.
This system also has lots of games and educational software installed. And even though theyre geared toward children, I guarantee youll enjoy playing with this system as well!
This CD has been built entirely from free software! Most software on this disk is freely available, open source software. A few are not open source, but are freely distributable.
This CD is still in its development stages, so keep an eye out for new versions.
Enhancements:
- Fixed bug in installer
- Installed latest updates from repository
- LBreakout2 is in the penalty box for bad language (Note: LBreakout will be back next version, without the bad language)

Safe and SafeDesktop project are created so that a user need not remember all her login names and passwords.
What is Safe?
Nowadays, every person is forced to remember lots of sensitive data to interact with machines during daily life. For instance, automatic teller machines ask for numerical passwords and email accounts are protected by using loginnames and passwords. For many good reasons passwords should be difficult to guess and every password should be used for one account only. In reality, this makes it quite difficult for the average person to remember all the different passwords. Hence, people tend to choose easy to remember passwords and many persons re-use their passwords in such a way that the same password is used for many accounts. Even worse, it is quite common to write down passwords and stick the note to a screen frame. All these facilitations of remembrance lower the burden for hackers to get access to sensitive data and abuse computers.
The idea behind Safe is that a user must not remember all her loginnames and passwords. Instead, the user utilizes her cell phone to store sensitive data in an encrypted way. Only one root password is required to be remembered to get access to the data.
This concept works pretty well, because nowadays, cell phones are ubiquitous. Usually, cell phone owners carry the phones in their pocket regardless where they are going. So, running Safe on a cell phone means that passwords have no longer be to remembered and can be chosen as difficult as it can be. The only requirement is that the cell phone in question supports J2ME applications.
What is SafeDesktop?
SafeDesktop provides the same features as Safe does but it runs on desktop machines. Java is also used for the implementation of SafeDesktop. This allows SafeDesktop to be executed on almost all modern desktop operating systems (e.g., Microsoft Windows, Linux).
A synchronization mechanism is part of SafeDesktop to keep the data synchronized between Safe and SafeDesktop.
How does it work?
First, a MD5 hash of the root password is stored and compared with the users input, that is requested at applications startup. If the hash of the users input is equal with the stored hash, the user input is used as key to decrypt the data.
Second, a IDEA cipher is used in CBC mode (of operation) to store data in an encrypted way. The password that the user entered at startup, is used as a key for the IDEA cipher.
Version restrictions:
- Safe and SafeDesktop have their limits. The limits are inherent - they came from the IDEA cipher, the hardware, the operating system and all the other parts that are used as a blackbox.
- But remember, there are things you can do to push the limits: review the source code of Safe and SafeDesktop. Even more security relevant: Select a difficult to remember, long and random root password. With Safe and SafeDesktop you have only to remember one password, so, make it difficult for the opposer to get access to your sensitive data.
Enhancements:
- An IPv6 problem has been fixed (no exception will be thrown when the machine uses IPv6).
- Exception handling has been improved (error messages provide hints as to what went wrong).
- A minor bug has been fixed (mainly how and when Alerts are shown).

Keep It Secret! Keep It Safe! (KisKis) is an easy-to-use password manager written in JAVA. So it runs on any platform with an appropriate Java-Virtual-Machine available (Windows, Linux, Solaris, ...).

It allows the user to manage passwords for many different purposes such as
network or internet accounts, credit-card-pin-numbers and password-secured-files. The accounts can be grouped hierarchically within a tree structure.

Each account can be described by multiple attributes (user name, URL, ...) and comments. The history of each password change can be tracked. Users can define their own account templates. Multiple file-attachments can be added to each account.

All passwords are stored in a single XML-file encrypted by a single "master- password". The encryption algorithm suffices the OpenPGP-standard, so you can verify the implementation with GPG or PGP. That means: You dont just have to believe me that your secrets are kept safe.

New passwords can be generated automatically in two distinct ways. The first is a secure approach generating totally randomized passwords, the second generates much more readable passwords.
