SeedCrackerX
Minecraft mod designed to reverse-engineer
SeedcrackerX is a Minecraft mod designed to reverse-engineer and determine a world’s seed by analyzing in-game structures and environmental data. It operates by collecting information from structures such as shipwrecks, temples, and monuments, then using that data to progressively narrow down possible seeds until the correct one is identified. The mod automates much of this process, initiating cracking procedures once sufficient data has been gathered, often requiring only exploration of specific structures. It includes a graphical configuration interface that allows users to control which structures are used and how data is collected. The system can also integrate with a shared database to contribute discovered seeds, enabling collaborative data gathering across users. Advanced features include brute-force algorithms that refine seed candidates based on structural patterns and hashed seed calculations. -

Google Authenticator Android
Open source fork of the Google Authenticator Android app
Google Authenticator for Android is the open-source two-factor authentication app that generates time-based (TOTP) and counter-based (HOTP) one-time codes entirely on the device. It’s designed to be simple, offline, and standards-compliant, so any service that supports OATH OTP can interoperate with it. The app streamlines enrollment via QR codes or manual key entry, then displays rotating numeric codes with clear account labels to reduce mistakes during login. Because secrets are stored on the device and codes are computed locally, it works even without a data connection and avoids server-side dependencies. The UI focuses on clarity and safety cues—timers, account naming, and basic management—to make 2FA adoption accessible to non-experts. For developers, the project doubles as a reference implementation of OTP enrollment, storage, and code generation on Android. -

Hypatia
A realtime malware scanner
Hypatia is a free and open-source malware scanner for Android that aims to provide on-device, real-time scanning with minimal battery and resource impact using signature-based detection inspired by ClamAV style databases. Designed as an Android app, it scans user filesystems and installed applications either on demand or in real time when files are written or renamed, operating completely offline aside from occasional signature database downloads. The project is offered under an AGPL-3.0 license and is archived in its original repository, reflecting a historical effort to create a community-reviewable FOSS security tool for Android devices. Hypatia’s design targets performance and efficiency, keeping memory usage modest and enabling users to control which signature sets are active. Its real-time file observation uses multi-threaded scanning to leverage device CPU resources while striving for a negligible user experience impact. -
