Destiny is an end-to-end encrypted file transfer app. No sign-ups. Opensource and TransparentDestiny is an end-to-end encrypted file transfer app. It allows people to securely send files without needing to reveal their identity to each other, or the service provider. No sign-up is needed.The user selects a file on their device and shares the generated code with the intended recipient for safe delivery.Destiny is based on the Magic Wormhole protocol.Key security features:- End-to-end encryption: Files are end-to-end encrypted and only the sender and recipient can read them.- Identity-less: No need to disclose identity information (such as name, email address, or phone number) to be able to transfer files.- Peer-to-peer file transfer: Destiny attempts to make a direct network connection to the other party. When this isn’t possible (for example, if neither party has a public IP address), then our relay server is used. However, that server sees only encrypted packets.- Full-strength keys: Although our codes are short and human-memorable, they are part of an online “Password Authenticated Key Exchange” (PAKE) which only allows a single guess – and yields a 256-bit full-strength symmetric key.

Mill Game program, which supports rule variants.Rules:* A player who aligns three pieces on a board line has a mill and may remove his opponent's piece(s).* Any player reduces to two pieces and has no option to form new mills and thus loses the game.* If a player cannot move one of his pieces (is locked up), he has lost the game.Features:* Support rule variants, such as Nine Men's Morris, Twelve Men's Morris,  "flying" rule, or no "flying" rule.* Play against the AI, or play both sides.* Adjustable playing strength.* Import/export move list.* Highly configurable.* Color themes.* Support accessibility.* Supports 45+ languages, such as English, Persian, German, Hungarian, Russian, Arabic, Czech, Romanian, Spanish, Portuguese, French, Italian, Polish, Turkish, Chinese, Japanese, Korean, and Hindi.Some strategy tips for beginners:* Playing on the cross points because they offer more way mobility to the pieces.* Corners are weak, as the player can only move in fewer directions.* Giving the piece space to move.* Do not make mills straight away. Usually, the first player to make a mill in the placement phase will easily get blocked.* Black has an advantage because it gets to place the last piece strategically.* Double attacks - be aware that players can attack two points simultaneously.




Sanmill is an open-source, UCI-like Mill/Morris/Merrills/Mühle/Malom (and its variants) program with CUI, Flutter GUI and Qt GUI, sharing and freely distributing the code, tools and data needed to deliver this mill game.

Protect your privacy and make free mobile phone calls over the internet with Simlar. Your calls are fully encrypted. Simlar is very easy to use. Just select your contact and call them! After installation, all of your contacts who also use Simlar will be listed in the app automatically. Maybe some of your friends already have Simlar. It is also available for other smartphone platforms.Simlar is based on the established end-to-end encryption protocol ZRTP. No one can listen to your conversation, not even us. During your first call, you need to match a short code with the person you are speaking to. This protects against man-in-the-middle attacks and only needs to be done once per contact. The app development is driven by the open source community. You can find the source code at simlar.org. Simlar is free of charge. All you need is an internet connection. The more stable your connection is, the better is your sound quality. The average “traffic” corresponds to 1 megabyte for a 2-minute call. For more details see simlar.org.
