Hash Droid is a free utility to calculate a hash from a given text or from a file stored on the device. In this application, the available hash functions are : Adler-32, CRC-32, Haval-128, MD2, MD4, MD5, RIPEMD-128, RIPEMD-160, SHA-1, SHA-256, SHA-384, SHA-512, Tiger and Whirlpool. The calculated hash can be copied to the clipboard to be reused elsewhere. The first tab enables to calculate the hash of a given string. The second tab helps you to compute the hash of a file located on the internal or external memory of your device. The size of the file and the last date modified are also displayed. The last feature helps you to compare the calculated hash with another given hash but more generally, you can compare any hashes by just pasting them. A hash (also called checksum or digest) is a digital fingerprint, uniquely identifying a string or a file. Hash functions are often used in cryptography to generate strong passwords. They are also employed to check the integrity of files. Hash Droid is often used to check an Android ROM before flashing it.

Haven is a Free and Open-Source app that leverages the "Work Profile" feature of Android to provide an isolated space that you can install or clone apps into. Haven uses the application id io.github.kennethchoinfosec.haven, so it installs as a separate app and does not upgrade or replace existing installs of the original app. The main use-cases of Haven include: - Installing apps inside a work profile for isolation - "Freeze" apps inside the work profile to prevent them from running or being woken up when you are not actively using them - Installing two copies of the same app on the same device Note that Haven depends on the Work Profile feature of the Android system, so any bugs related to Work Profiles in the Android-derived system you are using will affect Haven. In addition, Haven can only be as secure as the Work Profile implementation.

Haven is an app for people needing a way to protect their private sphere and possessions without compromising their own privacy. It turns the on-device sensors of any Android phone into a motion, sound, vibration and light detector, alerting you of unexpected guests and intruders in your physical spaces. By combining monitoring and device storage, with secure communications technologies, like Signal and Tor, it prevents the worst kind of people from silencing citizens without getting caught in the act. By protecting investigative journalists, human rights defenders, and people at risk of forced disappearance, a new kind of herd immunity is created.Safety through SensorsHaven only saves images and sound triggered by motion or volume, storing everything locally on your device. Position the device’s camera to capture visible motion, or place your phone somewhere discreet to listen just for noises. Get secure notifications of intrusion events instantly, and access logs remotely at any time.Sensors monitored for measurable change, recorded to the device event log:Accelerometer: Motion and vibration of phoneCamera: Motion in the phone’s visible surroundings from front or back cameraMicrophone: Noises in the environmentLight sensor: Triggered by sudden light changesPower: Detect device being unplugged, running out of battery or being shut downProject TeamHaven is a collaboration between the Guardian project, and the Freedom of the Press Foundation, which generously funded the Prototype stage. Continued work can be funded through their site: https://freedom.press/donate-support-haven-open-source-project

HiddenProtectedWorkProfile is copy of ProtectedWorkProfile app, which, unlike original, is hidden in work profile and launched via notification. Since app hides all other apps when screen turns off, hiding itself leads to hiding entire profile from launcher. This app creates work profile that will be frozen (encryption keys will be evicted from RAM) and that hide apps when your screen turns off. This app not visible in profile.

HideDroid allows the per-app anonymization of collected personal data according to a privacy level chosen by the user.In a nutshell, HideDroid collects all the network traffic generated by the invocation of API calls belonging to analytics libraries, and extract the exported data. Then, it anonymizes the personal and device data using a generalization technique, and the data related to the user’s behavior using an approach based on the concept of local differential privacy, in a way that preserves as much data semantics as possible. Finally, the anonymized data are sent to the expected recipients by mimicking the original network calls.

This is a simple Tool allowing you to share media and text with another Android User Profile as easily as forwarding it to another App. Android's User Profiles allow isolating Apps from each other such that users are able to keep sensitive applications separate from less trustworthy ones. No profile can access the apps, app data or files of another profile, but that also means that there's no easy way for for users of profiles to exchange information. With this App you'll be able to select which information you'd like to share with other profiles on the same device. Notifications about the shared data will be shown in the other profiles allowing you to download, share or copy it from the profile the data is located in. All inter-profile communications happen locally without requiring an Internet connection, the use of servers, or involvement of 3rd party services. No Ads. No Tracking. No In-App Purchases. Free Open Source Software.

Preserves privacy, prevents tracking, and provides access to restricted and hidden online content.InviZible Pro combines the strengths of Tor, DNSCrypt, and Purple I2P to provide a comprehensive solution for online privacy, security, and anonymity.Tor is responsible for privacy and anonymity. It acts like an unlimited free VPN proxy, but does so in the most secure way possible. Tor uses military-grade encryption and routes your internet traffic through a network of volunteer-run proxy servers. This helps protect your identity and location by hiding your IP address. It allows you to browse the internet anonymously, access websites that are otherwise restricted, and communicate privately. Tor also allows access to websites hosted on the Tor network, known as "onion services" or dark web, which are not accessible through regular browsers.DNSCrypt is responsible for security. Every phone uses DNS (Domain Name System) when visiting online resources. But this traffic is usually not encrypted and can be intercepted and spoofed by third parties. DNSCrypt ensures that your DNS traffic is encrypted and secure. It prevents unauthorized access and tampering of your DNS queries, providing an additional layer of protection against surveillance and data interception.I2P (Invisible Internet Project) provides secure and anonymous access to internal I2P websites, chat forums and other services that are not available through regular browsers. You may know it as the deep web. It works by routing your internet traffic through a network of volunteer-run proxy servers, allowing you to hide your identity and location.
