 Creating a plug-in for Keepass2Android or enabling your app to query credentials from Keepass2Android is pretty simple. Please follow the steps below to get started. In case you have any questions, please contact me.
 
 ## Preparations 
-First check out the source code and import the Keepass2AndroidPluginSDK from [https://keepass2android.codeplex.com/SourceControl/latest#src/java/Keepass2AndroidPluginSDK/](https://keepass2android.codeplex.com/SourceControl/latest#src/java/Keepass2AndroidPluginSDK/) into your workspace.

You should be able to build this library project.
 
 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://keepass2android.codeplex.com/SourceControl/latest#src/java/Keepass2AndroidPluginSDK/src/keepass2android/pluginsdk/Strings.java](https://keepass2android.codeplex.com/SourceControl/latest#src/java/Keepass2AndroidPluginSDK/src/keepass2android/pluginsdk/Strings.java).

 ## Modifying the entry view
 You can add menu options for the full entry or for individual fields of the entry when displayed to the user. This is done, for example, by the QR plugin ([https://play.google.com/store/apps/details?id=keepass2android.plugin.qr](https://play.google.com/store/apps/details?id=keepass2android.plugin.qr)).

 ## 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).

+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.
