strongSwan VPN Client
APK
Official Android port of the popular strongSwan VPN solution. # FEATURES AND LIMITATIONS # Uses the VpnService API featured by Android 4+. Devices by some manufacturers seem to lack support for this - strongSwan VPN Client won't work on these devices! Uses the IKEv2 key exchange protocol Uses IPsec for data traffic Full support for changed connectivity and mobility through MOBIKE (or reauthentication) Supports username/password EAP authentication (namely EAP-MSCHAPv2, EAP-MD5 and EAP-GTC) as well as RSA/ECDSA private key/certificate authentication to authenticate users, EAP-TLS with client certificates is also supported Combined RSA/ECDSA and EAP authentication is supported by using two authentication rounds as defined in RFC 4739 VPN server certificates are verified against the CA certificates pre-installed or installed by the user on the system. The CA or server certificates used to authenticate the server can also be imported directly into the app. IKEv2 fragmentation is supported if the VPN server supports it (strongSwan does so since 5.2.1) Split-tunneling allows sending only certain traffic through the VPN and/or excluding specific traffic from it Per-app VPN allows limiting the VPN connection to specific apps, or exclude them from using it The IPsec implementation currently supports the AES-CBC, AES-GCM, ChaCha20/Poly1305 and SHA1/SHA2 algorithms Passwords are currently stored as cleartext in the database (only if stored with a profile) VPN profiles may be imported from files Supports managed configurations via enterprise mobility management (EMM) Details and a changelog can be found in our documentation: https://docs.strongswan.org/docs/latest/os/androidVpnClient.html # PERMISSIONS # READ_EXTERNAL_STORAGE: Allows importing VPN profiles and CA certificates from external storage on some Android versions QUERY_ALL_PACKAGES: Required on Android 11+ to select apps to ex-/include in VPN profiles and the optional EAP-TNC use case # EXAMPLE SERVER CONFIGURATION # Example server configurations may be found in our documentation: https://docs.strongswan.org/docs/latest/os/androidVpnClient.html#_server_configuration Please note that the host name (or IP address) configured with a VPN profile in the app *must be* contained in the server certificate as subjectAltName extension. # FEEDBACK # Please post bug reports and feature requests via GitHub: https://github.com/strongswan/strongswan/issues/new/choose If you do so, please include information about your device (manufacturer, model, OS version etc.). The log file written by the key exchange service can be sent directly from within the application.

sub rosa by naiveHA
APK
Uncomplicated simple: if you manage your long, complicated and secure passwords in a password manager app (like KeePassDroid) on your Android device, you can now "type" them easily on any other device, be it a phone, tablet, or PC running Windows, Linux, or MacOS. sub rosa allows you to program (over USB or NFC) the static password of your YubiKey which then can be used to "type" the password with the touch of a finger. Once you are done "typing" your long, complicated and secure password, remember to wipe clean your YubiKey...

tagdrop
APK
TagDrop turns small files — text, HTML pages, images, audio, SVGs — into self-contained QR codes that work completely offline. Print one on a sticker or sheet of paper and leave it somewhere; anyone with the TagDrop app (or any QR scanner that follows tagdrop: links) can scan it and view the content immediately, with no internet connection, server, or account required. Think of it as a digital geocache: instead of a logbook in a box, the "cache" is the QR code itself. What you can do with it Drop a single page — encode text, an HTML page, an SVG image, or JSON into one QR code, either in-app (Create Cache) or with the web generator. Drop a whole "paper" — a printable sheet with a directory QR code (a paper manifest) plus one QR per file, built in-app (Create Paper) or with the web generator. Pages can link to each other with ordinary relative links, so a small static site survives being printed and scanned back in. Spread large content across multiple codes — split a payload too big for one QR into multiple sector codes placed along a trail. The app collects sectors in any order, reassembles and verifies them, and can recover a single missing sector from an optional parity code. Build trails, collections, and replies — link papers together with location hints, tag a loose set of stickers with a shared collection so they group into one card on the home screen and map, or mark a code as a reply to another to thread a conversation across drops. Browse offline — scanned pages render in an in-app viewer, with search and #hashtag filtering, and a hex/CBOR inspector for the curious. The Collections, History, and Map tabs let you revisit, locate, and manage everything you've found, and a single file can back up or restore it all. Tap instead of scan — write any TagDrop code to a blank or rewritable NFC tag, then read it back with a tap instead of the camera. How it works Every code carries a tagdrop: URI — a CBOR sequence (version, type, and payload map), Base41-encoded so it packs efficiently into a QR code's alphanumeric mode. Content can optionally be DEFLATE-compressed. IDs are content-addressed (SHA-256 based), so identical content always gets the same ID regardless of who created it. Status V2.1 — CBOR-sequence envelope encoding with content split into sectors plus optional parity recovery, paper manifests with multi-file directories and relative-link navigation, geographic trails via "related" hints, ad-hoc collections, reply threading, an in-app scanner with a live scan board, NFC tag read/write, search and #hashtag filtering, full backup/restore, and a Map tab for located finds.

toodoo
APK
Features of toodoo Tasks: You can create, change and delete tasks. Each task has a name, a category, a priority (HIGH, MEDIUM, or LOW), and a completion-status (i.e. it is either OPEN or DONE). Optionally, each task can also have a description (arbitrary text), a due_date and a due_time. In order to avoid unintentional deletion, a task can only be deleted if it is DONE. Categories: You can create as many categories as you need. The category a task belongs to can be changed. A category can be renamed. This will affect all tasks that belong to that category. Unused categories can be deleted. I.e. deletion is only possible if the category has no tasks, and if it is not used in the current filter. Filtering tasks: It is possible to restrict the tasks displayed in the list, e.g. completed tasks only, or tasks with low priority only, etc. In general, the tasks to be displayed in the list can be filtered by * completion_status * due_date/due_time * priority * category or any combination of these. For due_date there are several predefined filter options, e.g. TODAY, CURRENT_WEEK, OVERDUE, TASKS_WITHOUT_DATE, etc. For priority and category, it is possible to filter with more than one option. E.g. you can choose to show tasks with priorities HIGH or MEDIUM. Or you can display all tasks that have either category "Family" or "Friends". Sorting tasks: The task list can be sorted by: * completion_status * due_date/due_time * priority * category * name Any sort order is possible. E.g. first by due_date/time, then by completion status, category, priority and name. Or any other order you prefer. Searching tasks: Tasks can be searched by text. The search text you enter can be applied to the task name, the task description, or both. Case-sensitive search is possible. In the list of search results, when displaying details of a task, the search string is highlighted in the task name and / or description. Convenience: There are shortcuts for often used actions. E.g. * From the context menu of a category you can jump to a list of all tasks for that category. * From the context menu of a task you can change its completion_status, set it to DONE (or OPEN respectively), or set its due date to today or tomorrow. * When the task list is filtered by "tasks due TODAY", you can easily move to the previous / next day by swiping right / left. * Similarly, by swiping you can easily move to the previous / next week (when the task list is filtered by "tasks due CURRENT_WEEK"), or to the previous / next category (when all tasks for a category are displayed). Display: Tasks due in the past, today, or in the future have different background colors, so they are easily discernible. The color scheme adapts to the display mode of the underlying android. I.e. if dark mode is selected (provided your android does support dark mode), a dark color scheme is used also for toodoo. Import / Export: All user data (i.e. tasks, categories, filters and sort criteria) can be exported to an external file (xml-format). Vice versa, data can be imported from an external file. Technical: Your data is stored locally on your device. No connection to the internet needed. No ads. No tracking. Restrictions toodoo is minimalistic. It focuses on managing, categorizing, filtering, and sorting tasks (however, more features may be added in future releases.) Thus, there are some restriction, i.e.: * The user interface is in English only. * Name of folder and file for export data are fixed (i.e. /Download/toodoo/toodooData-yyyy-mm-dd-hh-mm-ss) * Settings are currently fixed, e.g. - date format is yyyy-mm-dd, time format is 24 hours. - first day of week is Monday. - within a day, tasks without due_time are sorted behind tasks with due_time.
