Free secret of eternia software for linux

Secret of Eternia project is a 2D RPG using ClanLib.
The eaisest way to get started is to use an example map from the game itself. Open up (File-Open) the first map in the maps/ folder (maps/1.fmp). You will notice that the map looks exactly like the first screen of the game demo!
You will notice the screen is divided into 2 main sections. The larger section is the preview of the map you are working on. The left side menu is a listing of all avaliable blocks that you currently have in the map. You can click on a block to set it as your current brush. This is similar to choosing a paint color in a paint program. Once you select a block, you can then edit the map by clicking in the map area. This is the generic way to edit the map.
Play around with this map to create some different landscapes and such using many blocks. You can even save the map and start up SoE to see your changes! (Make sure you have a backup of the original map, or you will have to download the game again).
Enhancements:
- Bug fixes! See the forum for detailed information.
- Lua support is added in. (see docs/ for how to use this)
- Lighting effects are here!
- Fully Working Windows Support

Secret Squirrel project is a password manager.
Secret Squirrel is a basic password management application written in Java.
It uses Blowfish and SHA-384, performs password generation using the Java secure random object (fully configurable), and supports password groups
Main features:
- JavaBlowfish encryption
- SHA-384 of passwords
- Password generation (fully configurable)
- Password groups
- Cross-platform (java)
- Software keyboard to bypass key capture programs
- Double-click to put password into clipboard

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.

Secret::Simple are secure secrets in configurations and code.

SYNOPSIS

# OOP style
my $ss = Secret::Simple->new();
my $ciphertext = $ss->encrypt($plaintext);
my $plaintext = $ss->decrypt($ciphertext);

# procedural style
my $ciphertext = ssencrypt($plaintext);
my $plaintext = ssdecrypt($ciphertext);

This module implements a straightforward interface for encrypting and decrypting secret information such as user IDs and passwords (e.g. database connection or remote account credentials). Secret::Simple can also be used on a limited basis to protect arbitrary data. By default the ciphertext returned is Base 64 encoded so as to be easily embedded within configurations or scripts.

A command-line utility called sstool is included to facilitate easy manipulation of cipher and plaintext snippets. The encryption mechanism utilizes the strong AES algorithm, so any weaknesses in Secret::Simple predominantly lie in how keys are protected. A balance must be struck between key accessibility, key protection, and overall complexity. The calling code can supply a key, series of keys, key files, or a combination. If no key information is explicitly passed, the module will attempt to use the OS users private SSH DSA key file by default if it exists.

The major goal of this module is to be as secure as possible while being simple and convenient enough to encourage its use. Psychology does factor in: simple is a very important consideration. If the security methods are too onerous or complicated to use, many sysadmins or developers may simply use plaintext (no protection other that OS file permissions) or simple ciphers like rot13. The security of the Secret::Simple method is not perfect, but it does represent a significant improvement over commonly-used nonsecure methods of embedding credentials and other secrets in Perl configurations and scripts. If used appropriately, Secret::Simple can greatly improve application and configuration security. Even so, care must always be taken to protect files and file permissions.

GREYCstoration is an image regularization algorithm which processes an image by locally removing small variations of pixel intensities while preserving significant global image features, such as sharp edges and corners.
The most direct application of image regularization is denoising. By extension, GREYCstoration can also be used to inpaint or resize images.
GREYCstoration is based on state-of-the-art methods using nonlinear multi-valued diffusion PDEs (Partial Differential Equations) for image regularization. This kind of method generally outperforms basic image filtering techniques (such as convolution, median filtering, etc.), classically encountered in painting programs.
Other image denoising plugins are available (for instance, Noise Ninja, Neat Image ) but are not free, and the corresponding algorithms are kept secret.
Enhancements:
- This release consumes far less memory than the previous version (2.4.2), so it can deal with very large images.
- There are now processing modes for 16-bit/components and 32-bit float-valued images, as well as multi-thread support.
- A brand new plug-in for the GIMP is provided.

Crypt::Util is a lightweight Crypt/Digest convenience API.

SYNOPSIS

use Crypto::Util; # also has a Sub::Exporter to return functions wrapping a default instance

my $util = Crypto::Util->new;

$util->default_key("my secret");

# MAC or cipher+digest based tamper resistent encapsulation
# (uses Storable on $data if necessary)
my $tamper_resistent_string = $util->tamper_proof( $data );

my $verified = $util->thaw_tamper_proof( $untrusted_string, key => "another secret" );

# If the encoding is unspecified, base32 is used
# (hex if base32 is unavailable)
my $encoded = $util->encode_string( $bytes );

my $hash = $util->digest( $bytes, digest => "md5" );

die "baaaad" unless $util->verify_hash(
hash => $hash,
data => $bytes,
digest => "md5",
);
