sub rosa by naiveHA

sub rosa by naiveHA is an open-source security application for Android devices. It is designed to configure a YubiKey with a static password and use the hardware security key to enter that password. The configured key can be used with phones, tablets, and computers.

The application is intended for people who want to use a hardware security key when entering a password across these devices. It also supports programming OpenPGP keys to a compatible hardware security key. This places the app in the security category because it connects password and key handling with dedicated hardware.

Its central purpose is configuration rather than serving as a general-purpose password manager. A static password is stored on the hardware security key so that the key can provide it when needed. The Android version provides the mobile platform through which this setup is performed.

Because the project is open-source, its source code is available under an open-source license rather than being distributed only as closed software. That licensing model allows the software to be examined and used according to the terms of its license. The app is relevant to users who already have a YubiKey and want to configure it from an Android phone or tablet.

It may also be useful to users who work with OpenPGP keys and want to program them onto supported hardware. MirrorNest distributes the official build of sub rosa by naiveHA by mirroring it directly on its own storage. Before publishing the mirrored build, MirrorNest scans it for malware.

This distribution process gives MirrorNest users a separately hosted copy while keeping the package tied to the official build. As an Android security utility, sub rosa by naiveHA focuses on hardware-based password entry and key configuration rather than unrelated device functions.
