    Aegis Authenticator

    Aegis Authenticator

    A free, secure and open source app for Android

    Aegis Authenticator is a free and open-source two-factor authentication (2FA) app for Android that helps users secure their online accounts by generating cryptographic one-time passwords (OTPs) such as TOTP and HOTP codes. Unlike many proprietary MFA apps, Aegis is designed with user privacy and local control in mind, storing secrets only on the device in an encrypted vault protected by PIN or biometric unlock, and offering features like backups encrypted with a user-chosen passphrase. It supports importing accounts from QR codes, exporting encrypted backups for safe storage, and grouping or labeling tokens so managing dozens of accounts is simple. Aegis also offers options for custom token configuration, including changing issuer names, digits, and intervals, and includes a robust recovery mechanism in case a device is lost. It has a material design interface that makes navigation intuitive, and its open-source license ensures transparency.

    IOS6 and recent iTunes updates have broken a few features. We have made some partial fixes, but they are not complete. If you'd like to help support our development, or take over the development please let us know. Explore the internal file structure of your iphone (or of a seized phone in the case of forensic teams) using either the iphone's own backup files or (for jail broken iphones) ssh. Viewing of plist, sqlite, and hex are supported. IOS 5 is now supported iOS 6 only partially works at the moment (some features fail or are missing). Unfortunately paid work means we can't fix this right now, but would welcome anyone else submitting patches.

    hyperion-project

    hyperion-project

    An open source ambient light for many systems

    Hyperion is an open source ambient light implementation controlled primarily by an Raspberry Pi. The main features of Hyperion are: 1. Low CPU load. For a led string of 50 leds the CPU usage will typically be below 2% on a non-overclocked Pi. 2. Json interface which allows easy integration into scripts. 3. A command line utility allows easy testing and configuration of the color transforms (Transformation settings are not preserved over a restart at the moment...). 4. Priority channels are not coupled to a specific led data provider which means that a provider can post led data and leave without the need to maintain a connection to Hyperion. This is ideal for a remote application (like our Android app). 5. HyperCon. A tool which helps generate a Hyperion configuration file. The tool will also remember your settings from the previous run. 6 Android remote control to set a static color. 7.Kodi-checker which checks the playing and screensaver status of Kodi
