-# How to build Keepass2Android
-
-## Overview
-
-Keepass2Android is a Mono for Android app. This means that you need Xamarin's Mono for Android to build it. However, it also uses several components written in Java, so there are also Android-Studio projects involved. To make things even worse, parts of the keyboard and kdb-library are written in native code.
-
-To build KP2A from scratch, you need:
-- Xamarin's Mono for Android (also included in Visual Studio)
-- Android SDK & NDK
-
-Prior to building Keepass2Android, you need to build some of its components (from command line). Then you can build the full project either through Visual Studio, or through command line.
-
-By using the command line, you can build on Windows, macOS or Linux.
-
-## Prerequisites
-
-### Common to all architectures
-- Install Android SDK & NDK (either manually with Google's [sdkmanager](https://developer.android.com/studio/command-line/sdkmanager), or through Android Studio). Visual Studio also installs a version of it, but in the end the directory must be writable and in a path without spaces (see below) so as to be able to build the components.
-- Fetch the main repository of Keepass2Android and all submodules
-    - Note that VisualStudio can do this for you, otherwise run:
-    - `git submodule init && git submodule update`
-
-### On Windows or macOS
-- Install Visual Studio (for example 2019) with Xamarin.Android (ie. with capability to build Android apps). This should provide the needed tools like
-    - Xamarin.Android
-    - MSBuild
-    - Java JDK
-- If you plan to build also from the command line:
-    - Install the MSVC build tools of visual studio. They provide the `vcvarsall.bat` file which among other things adds MSBuild to the PATH.
-    - Install [NuGet](https://www.nuget.org/downloads) to build also with "make". Alternatively, on Windows, if you use [chocolatey](https://chocolatey.org), run as administrator:
-      - `choco install nuget.commandline`
-    - Check that you have access to 'GNU make'.
-      - On Windows, it is usually not available by default. But the Android NDK provides it. You can find it in `%ANDROID_NDK_ROOT%\prebuilt\windows-x86_64\bin\make.exe`.  Alternatively, on Windows, if you use [chocolatey](https://chocolatey.org), run as administrator:
-        - `choco install make`
-      - On macOS, it is usually only installed if you have developer command line tools installed or if you use [homebrew](https://brew.sh) or [macports](https://www.macports.org/). As an alternative it may be available in the Android NDK at `%ANDROID_NDK_ROOT%/prebuilt/darwin-x86_64/bin/make`.
-
-### On Linux
-- Install Java's JDK
-    - On Debian, for example: `apt install default-jdk-headless`.
-
-- Install [Mono](https://www.mono-project.com/)
-    - This should provide `msbuild` & `xabuild` binary
-    - On Debian, after having added the repo from above, install with `apt install -t <repo_name> mono-devel msbuild`. A value for `<repo_name>` could be `stable-buster` for example, depending on which one you chose. You could also install the `mono-complete` package if you prefer.
-
-- Install Xamarin.Android
-  - ~~Option 1: Use the mono-project [CI builds](https://dev.azure.com/xamarin/public/_build/latest?definitionId=48&branchName=main&stageName=Linux)~~ **NOTE:** KP2A now requires Xamarin.Android v13, which is newer than the current CI build; until a more recent CI build is available, this option is unfortunately no longer viable.
-  - Option 2: [Build it from source](https://github.com/xamarin/xamarin-android/blob/master/Documentation/README.md#building-from-source)
-
-- Install NuGet package of your distribution
-    - On Debian/Ubuntu: `apt install nuget`
-
-- Install [libzip](https://libzip.org/) for your distribution for some Xamarin.Android versions
-  - This may not be relevant anymore: for example, with Xamarin.Android 11.4.99. this is not needed.
-  - Some versions of Xamarin may require `libzip4`. If you are in this case:
-    - On Debian/Ubuntu, install it with `apt install libzip4`.
-    - Other distributions ship only `libzip5`. As a dirty workaround, it's possible to symlink `libzip.so.5` to `libzip.so.4`. Luckily, it appears to be working. For example:
-      - `sudo ln -s /usr/lib/libzip.so.5 /usr/lib/libzip.so.4`
-      - or `sudo ln -s /usr/lib64/libzip.so.5 /usr/lib/libzip.so.4`
-
-## Building the required components:
-
-This is done on the command line and requires the Android SDK & NDK and Java JDK.
-
-### On Windows
-- Setup your environment:
-  - Set these environment variables for Android's SDK & NDK
-    - `ANDROID_HOME` (for example `set ANDROID_HOME=C:\PATH\TO\android-sdk`)
-    - `ANDROID_SDK_ROOT` (for example `set ANDROID_SDK_ROOT=C:\PATH\TO\android-sdk`)
-    - `ANDROID_NDK_ROOT` (for example `set ANDROID_NDK_ROOT=C:\PATH\TO\android-sdk\ndk\version`)
-    
-    **Note:** Care must be taken when setting the above variables to **not** include a trailing backslash in the path. A trailing backslash may cause `make` to fail.
-
-    **Note**: If the path to the Android SDK contains spaces, you **must** do one of these:
-    - either put the Android SDK into a path without spaces.
-    - or create a symlink to that path which doesn't contain spaces. Attention: this requires **administrator** priveleges. For example:
-
-        ```
-        IF NOT EXIST C:\Android ( MKDIR C:\Android ) && 
-        MKLINK /D C:\Android\android-sdk "C:\Program Files (x86)\Android\android-sdk" 
-        ```
-    This is because [Android NDK doesn't support being installed in a path with spaces](https://github.com/android/ndk/issues/1400).
-
-    **Note**: The Android SDK path will require to be writeable because during the build, some missing components might be downloaded & installed.
-
-- If you have "GNU make" available on your windows system, you may build by using the Makefile. You can also find a `make` executable in `%ANDROID_NDK_ROOT%\prebuilt\windows-x86_64\bin\make.exe`. To use it, see the instructions for Linux/macOS. Basically, just run `make` or `mingw32-make` depending on which distribution of GNU make for windows you have installed.
-
-- Otherwise proceed as below:
-
-    1. Build argon2
-
-        ```
-        cd src/java/argon2
-        %ANDROID_NDK_ROOT%/ndk-build.cmd
-        ```
-    1. Build the other java components
-
-        ```
-        cd src/build-scripts
-        build-java.bat
-        ```
-
-        `build-java.bat` will call `gradlew` for several Java modules.
-
-**Notes:**
-
- - For building the java parts, it is suggested to keep a short name (e.g. "c:\projects\keepass2android") for the root project directory. Otherwise the Windows path length limit might be hit when building.
- - Before building the java parts, make sure you have set the ANDROID_HOME variable or create a local.properties file inside the directories with a gradlew file. It is recommended to use the same SDK location as that of the Xamarin build.
- - On some environments, `make` can fail to properly use the detected `MSBUILD` tools. This seems to be due to long pathnames and/or spaces in pathnames. It may be required to explicitly set the `MSBUILD` path using 8.3 "short" path notation:
- 	- Determine the location of `MSBUILD` (e.g. `C:\Program Files\Microsoft Visual Studio\2022\Community\MSBuild\Current\Bin\MSBuild.exe`)
- 	- [Generate the "short" path](https://superuser.com/a/728792) of that location (e.g.: `C:\PROGRA~1\MICROS~2\2022\COMMUN~1\MSBuild\Current\Bin\MSBuild.exe`)
- 	- When running `make` specify the location of ``MSBUILD` explicitly (e.g.: `make MSBUILD="C:\PROGRA~1\MICROS~2\2022\COMMUN~1\MSBuild\Current\Bin\MSBuild.exe` 
-
-
-### On Linux/macOS
-
-- Setup your environment:
-  - Set these environment variables for Android's SDK & NDK

-
-## Building Keepass2Android:
-
-These are the basic steps to build Keepass2Android. You can also build Keepass2Android Offline. For this, configure the build by using the [Flavors](#Flavors).
-
-### With Visual Studio
-
-- On windows or on macOS open the src/KeePass.sln file with visual studio, and choose to build the project named 'keepass2android-app'
-
-### Command Line
-
-#### Windows, Macos & Linux
-to build the APK, simply run:
-
-```
-    make
-```
-
-or to skip building the APK:
-
-```
-    make msbuild
-```
-
-## Where is the APK ?
-The Apk can be installed on a device.
-It is located in `src/keepass2android/bin/*/*-Signed.apk`
-
-If you build with Visual Studio, the APK is not produced automatically. You need to perform some extra step. See the documentation of Visual Studio on how to proceed.
-
-## Flavors
-
-Keepass2Android is distributed in two flavors.
-  - Keepass2Android (aka `net`)
-  - Keepass2Android Offline (aka `nonet`)
-
-The flavor is set through a MSBuild Property named "`Flavor`". The possible values are '`Net`' and '`NoNet`'.
-
-The value of the Flavor property is used in 2 projects:
-  - `keepass2android-app` (in `src/keepass2android`)
-  - `Kp2aBusinessLogic` (in `src/keepass2android`)
-
-Its value is set inside the `*.csproj` file (XML format) of each project in the `Project`/`PropertyGroup`/`Flavor` node.
-By default its value is set to an empty string so that development is made with `AndroidManifest_debug.xml` on the '`net`' flavor.
-
-This is the behaviour of the build system depending on the value of Flavor:
-| Flavor                                     | What is built           | `AndroidManifest.xml` used  |
-| -----                                      | -----                   | -----                       |
-| `` (empty string): This is the default value. | Keepass2Android      | `AndroidManifest_debug.xml` |
-| `Net`                                      | Keepass2Android         | `AndroidManifest_net.xml`   |
-| `NoNet`                                    | Keepass2Android Offline | `AndroidManifest_nonet.xml` |
-
-### Select/Change flavor:
-
-When building, by default, the flavor is not set. So the value used is the value of the Flavor property in *.csproj file. This should result on doing a build of the 'net' flavor.
-
-You can force the Flavor by setting the Flavor property.
-
-Proceed this way:
-
-#### Command line
-
-##### Windows, Macos & Linux
-
-To force building 'net' with `make`, run:
-
-```
-    make Flavor=Net
-```
-
-To build 'nonet' with `make`, run:
-
-```
-    make Flavor=NoNet
-```
-
-##### MSBuild
-
-To build with MSBuild directly on the command line, set the flavor with `-p:Flavor=value` argument. For example:
-
-```
-    MSBuild src/KeePass.sln ... -p:Flavor=NoNet
-```
-
-#### Visual Studio
-When building with Visual Studio, edit the `*.csproj` file (XML format) and set the value in the `Project`/`PropertyGroup`/`Flavor` node. This is needed only for the projects that use the flavors.
-
-**Note:** When switching between flavors, be sure to clean the previous build before.
-
-## Makefile
-
-It is possible to override the project's default 'Flavor' (Net, NoNet) and 'Configuration' (Release, Debug) by passing it as argument to `make`. See the header of the Makefile to see what can be done.

-
-## TOTP in brief
-TOTP stands for [Time-based One-Time Password algorithm](https://en.wikipedia.org/wiki/Time-based_One-time_Password_algorithm) which is one of the most common way proposed by websites to do a [two-factor authentication (2FA)](https://en.wikipedia.org/wiki/Multi-factor_authentication).
-
-On these websites, this option will often be mentioned in the 2FA configuration menu as things like "_use code generated by an application_", "_use [Google] Authenticator app_".
-
-You're prompted to scan a QR code with the app, which essentially contains a code called "_seed_", usually with a form like "_AZER TYUI OPQS DFGH JKLM_", used to generate TOTPs. The seed can be also directly copied if there is no scanning option on the app.
-
-Most common apps: 
-
-- Google Authenticator
-- Authy
-- Microsoft Authenticator
-- FreeOTP
-- LastPass Authenticator
-
-## TOTP in KeePass and benefits
-In KeePass (by Dominik Reichl) there is are several ways to enable this Authenticator app ability: 
-
-- built-in TOTP support: https://keepass.info/help/base/placeholders.html#otp
-- [KeePassOTP plugin](https://keepass.info/plugins.html#kpotp)
-- [KeeOtp plugin](https://keepass.info/plugins.html#keeotp)
-- [KeeTrayTOTP plugin](https://keepass.info/plugins.html#keetraytotp) (note the name "_TrayTOTP_" on this one for later)
-
-KeePassXC also supports TOTP: https://keepassxc.org/docs/KeePassXC_UserGuide#_adding_totp_to_an_entry
-
-The greatest benefits are:
-
-- the seed stays available contrary to the above apps (for which it's more or less hard to backup/restore/switch with another app)
-- TOTPs are available wherever the KeePass database is available. But conceptually it's not really 2FA anymore (all things are stored in the same place).
-
-The different implementations use different ways of storing the TOTP seed (or secret, or key) and optional settings (e.g. the length of the TOTP to generate) within an entry inside the kdbx database. Keepass2Android attempts to be able to read the different formats, but can only write one:
-
-## TOTP in Keepass2Android 
-
-If you use any of the tools mentioned above, you can set up TOTP entries with them. Keepass2Android can read those entries and generate TOTPs if any of the following styles are used:
-
-* Keepass2 style: used when there are TimeOtp-Secret(-XXX) fields in the entry
-* KeeOtpPlugin style: used when there is an otp field containing a query string in the form of key=abc&step=X&size=Y (step and size are optional)
-* KeeWebOtp/Key Uri Format style: used when entry contains a URL starting with otpauth://totp/, e.g. otpauth://totp/?secret=abc (https://github.com/google/google-authenticator/wiki/Key-Uri-Format)
-* KeeTrayTotp style:
-  * requires a non-empty seed field (default key is "TOTP seed", can be changed in KP2A settings), value is base32 encoded data
-  * requires a non-empty settings field (default key is "TOTP Settings", can be changed as well), value is expected to be a csv-separated array with [Duration];Length(;TimeCorrectionURL). Length is either an integer value or "S" to indicate Steam encoding
-
-In order to view the generated TOTP code in KP2A, open the corresponding entry. You can then
- * use a dynamically generated field called "_TOTP_" containing the TOTP  or
- * use the "Copy TOTP" button on the system notification for the selected entry or
- * switch to the KP2A keyboard and use the TOTP button to insert the TOTP value into the target app or browser
-
-If you want to configure an entry to contain the TOTP fields, it is suggested to enter edit mode for the entry. Then click the "Configure TOTP" button. You can either enter the data manually or scan a QR code with the information.
- 
-### Spaces in otp field
- Make sure that the URI doesn't contain spaces, otherwise KeePass2Android will fail to generate TOTPs as a space is an invalid character. If your URIs have spaces, check [this comment](https://github.com/PhilippC/keepass2android/issues/1248#issuecomment-628035961)._

 Now add a reference to the PluginSDK library from your existing app or add a new plug-in app and then add the reference. 
 
 ## Authorization
 
-Keepass2Android stores very sensitive user data and therefore implements a plug-in authorization scheme based on broadcasts sent between the plug-in and the host app (=Keepass2Android or Keepass2Android Offline). Before your app/plug-in gets any information from KP2A, the user will have to grant your app/plug-in access to KP2A. As not every app/plug-in requires access to all information, you must specify which scopes are required by your app. The implemented scopes can be found in [https://github.com/PhilippC/keepass2android/tree/master/src/java/Keepass2AndroidPluginSDK2/src/keepass2android/pluginsdk/Strings.java](https://github.com/PhilippC/keepass2android/tree/master/src/java/Keepass2AndroidPluginSDK2/src/keepass2android/pluginsdk/Strings.java).

 ## Querying credentials
 KP2A 0.9.4 adds a great opportunity for third party apps: Instead of prompting the user to enter credentials or a passphrase, the app should try to get the data from KP2A if it is installed: If the user grants (or previously granted) access for the app,  KP2A will automatically retrieve the matching entry. User action is only required if the KP2A database is locked (user will usually unlock it with the short QuickUnlock code) or if no matching entry is found (user can then create a new entry or select an existing one. in the latter case KP2A will offer to add entry information so that the entry will be found automatically next time).

-# SFTP Open/Create Database Credentials Documentation
-
-## Basic Settings
-* **Host** -- the hostname or IP address of the SFTP server to connect to
-* **Port** -- the listening TCP port of the SFTP server to connect to (default: 22)
-* **Username** -- the user/account name on the SFTP server that has access to the database
-* **Initial directory** -- The path on the SFTP server that will be used as a starting point when choosing the remote database file
-
-### Authentication Modes
-
-#### Password
-Authenticate using a password
-
-* **Password** -- the password associated with **username** used to log into the SFTP server
-
-#### K2A Private/Public Key
-Authenticate using a private/public key pair that is generated internally by KP2A
-
-* **SEND PUBLIC KEY...** -- Opens a standard Android "Share" screen containing the KP2A public key content. This allows for the public key to be sent via email, SMS, etc. This public key will need to be added to the SFTP server's user's "authorized keys" to allow private/public key authentication.
-
-#### Custom Private Key
-Authenticate using an existing private/public key pair. Use this option instead of *K2A Private/Public Key* if you wish to use a key pair that is already set up for this **username** on the SFTP server.
-
-* **Selected private key** -- a combo-box containing a list of custom private keys that KP2A knows about, and a special `[Add new...]` option.
-##### Add A New Private Key
-* Select `[Add new...]`
-* Enter a name for the new key in **New key name**
-* Enter the private key contents (text) into **New key content**. **TIP:** The easiest way to accomplish this is to open the private key file in a text editor on the device, **Select All**, **Copy** to the clipboard, and paste it into **New key content**.
-* Tap **SAVE PRIVATE KEY** to add the new key to the known list.
-
-##### Use An Existing Private Key
-* To use a private key that has already been imported into KP2A, simply select it from the list of keys.
-
-##### Remove An Existing Key
-* To remove a private that has been imported into KP2A, select it from the list and tap **DELETE PRIVATE KEY**.
-
-A **key passphrase** can be supplied (if the key pair requires it)
-
-## Advanced Settings
-* **Connection timeout seconds** -- the number of seconds to wait for a connection to the server before giving up and considering the server as unavailable/unreachable
-
-### Key Algorithm Manipulation
-**NOTE: It is very rare that these fields need to be (or should be) specified. Use at your own risk!**
-
-* **Key Exchange (KEX) Algorithm(s)** -- Explicitly set or modify the ordered list of Key Exchange algorithms that the SSH/SFTP client library will try to use
-* **Server Host Key Algorithm(s)** -- Explicitly set or modify the ordered list of Server Host Key algorithms that the SSH/SFTP client library will try to use
-
-#### How It Works
-The SSH/SFTP client has a pre-defined ordered list of algorithm names that it will use to negotiate with the server to handle key exchange. In rare cases there are compatibility issues where Android OS has not properly implemented full support for algorithms listed. This can result in a connection failure, even if there is a suitable algorithm available (of lesser priority in the list).
-
-The fields listed above allow these lists to be manipulated in the following ways to overcome/workaround such problems. The value is a comma-separated list of "algorithm spec" entries. Specs can be one of:
-
-* Direct replacement of values -- Ex: `primary_alg,secondary_alg`
-* Prepend to values -- Ex: `+try_first_alg`
-* Append to values -- Ex: `try_last_alg+`
-* Remove a specific value -- Ex: `-bad_alg`
-* Remove values matching prefix -- Ex: `-bad_starting_with*`
-* Remove values matching suffix -- Ex: `-*bad_ending_with`
-* Remove values matching substring -- Ex: `-*bad_middle*`
-* Remove values matching prefix and suffix -- Ex: `-alg_begin*end`
-
-For example, assume the system's KEX algorithm list is:
-`ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group-exchange-sha256,diffie-hellman-group16-sha512,diffie-hellman-group18-sha512,diffie-hellman-group14-sha256`
-
-These are various outcomes (user KEX field -> result):
-
-* Prefix removal: `-ec*` --> `diffie-hellman-group-exchange-sha256,diffie-hellman-group16-sha512,diffie-hellman-group18-sha512,diffie-hellman-group14-sha256`
-* Suffix removal, appending: `-*256,+first_alg,almost_last_alg+,last_alg+` --> `first_alg,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group16-sha512,diffie-hellman-group18-sha512,almost_last_alg,last_alg`
-* Direct replacement: `first_alg,middle_alg,last_alg` --> `first_alg,middle_alg,last_alg`
-
-## Selecting A Database
-Once all applicable fields have been entered and/or options selected, tapping **OK** will attempt to connect to the SFTP server. First time connections may pop up a dialog window asking to accept the host's authenticity (tap **yes** if the host is trusted), as well as potentially creating a new `known_hosts` file (tap **yes** to do so). If the connection is successful, a remote file browser screen will open. Navigate and select the Keepass database to open.
