+  <!-- 
+    Microsoft ResX Schema 
+    
+    Version 2.0
+    
+    The primary goals of this format is to allow a simple XML format 
+    that is mostly human readable. The generation and parsing of the 
+    various data types are done through the TypeConverter classes 
+    associated with the data types.
+    
+    Example:
+    
+    ... ado.net/XML headers & schema ...
+    <resheader name="resmimetype">text/microsoft-resx</resheader>
+    <resheader name="version">2.0</resheader>
+    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
+    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
+    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
+    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
+    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
+        <value>[base64 mime encoded serialized .NET Framework object]</value>
+    </data>
+    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
+        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
+        <comment>This is a comment</comment>
+    </data>
+                
+    There are any number of "resheader" rows that contain simple 
+    name/value pairs.
+    
+    Each data row contains a name, and value. The row also contains a 
+    type or mimetype. Type corresponds to a .NET class that support 
+    text/value conversion through the TypeConverter architecture. 
+    Classes that don't support this are serialized and stored with the 
+    mimetype set.
+    
+    The mimetype is used for serialized objects, and tells the 
+    ResXResourceReader how to depersist the object. This is currently not 
+    extensible. For a given mimetype the value must be set accordingly:
+    
+    Note - application/x-microsoft.net.object.binary.base64 is the format 
+    that the ResXResourceWriter will generate, however the reader can 
+    read any of the formats listed below.
+    
+    mimetype: application/x-microsoft.net.object.binary.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
+            : and then encoded with base64 encoding.
+    
+    mimetype: application/x-microsoft.net.object.soap.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
+            : and then encoded with base64 encoding.
+
+    mimetype: application/x-microsoft.net.object.bytearray.base64
+    value   : The object must be serialized into a byte array 
+            : using a System.ComponentModel.TypeConverter
+            : and then encoded with base64 encoding.

+    Microsoft ResX Schema 
+    
+    Version 2.0
+    
+    The primary goals of this format is to allow a simple XML format 
+    that is mostly human readable. The generation and parsing of the 
+    various data types are done through the TypeConverter classes 
+    associated with the data types.
+    
+    Example:
+    
+    ... ado.net/XML headers & schema ...
+    <resheader name="resmimetype">text/microsoft-resx</resheader>
+    <resheader name="version">2.0</resheader>
+    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
+    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
+    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
+    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
+    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
+        <value>[base64 mime encoded serialized .NET Framework object]</value>
+    </data>
+    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
+        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
+        <comment>This is a comment</comment>
+    </data>
+                
+    There are any number of "resheader" rows that contain simple 
+    name/value pairs.
+    
+    Each data row contains a name, and value. The row also contains a 
+    type or mimetype. Type corresponds to a .NET class that support 
+    text/value conversion through the TypeConverter architecture. 
+    Classes that don't support this are serialized and stored with the 
+    mimetype set.
+    
+    The mimetype is used for serialized objects, and tells the 
+    ResXResourceReader how to depersist the object. This is currently not 
+    extensible. For a given mimetype the value must be set accordingly:
+    
+    Note - application/x-microsoft.net.object.binary.base64 is the format 
+    that the ResXResourceWriter will generate, however the reader can 
+    read any of the formats listed below.
+    
+    mimetype: application/x-microsoft.net.object.binary.base64
+    value   : The object must be serialized with 
+            : System.Serialization.Formatters.Binary.BinaryFormatter
+            : and then encoded with base64 encoding.
+    
+    mimetype: application/x-microsoft.net.object.soap.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
+            : and then encoded with base64 encoding.
+
+    mimetype: application/x-microsoft.net.object.bytearray.base64
+    value   : The object must be serialized into a byte array 
+            : using a System.ComponentModel.TypeConverter
+            : and then encoded with base64 encoding.

-# The Bouncy Castle Crypto Package For C Sharp
-
-The Bouncy Castle Crypto package is a C\# implementation of cryptographic algorithms and protocols, it was developed by the Legion of the Bouncy Castle, a registered Australian Charity, with a little help! The Legion, and the latest goings on with this package, can be found at [http://www.bouncycastle.org](http://www.bouncycastle.org). In addition to providing basic cryptography algorithms, the package also provides support for CMS, TSP, X.509 certificate generation and a variety of other standards such as OpenPGP.
-
-The Legion also gratefully acknowledges the contributions made to this package by others (see [here](http://www.bouncycastle.org/csharp/contributors.html) for the current list). If you would like to contribute to our efforts please feel free to get in touch with us or visit our [donations page](https://www.bouncycastle.org/donate), sponsor some specific work, or purchase a support contract through [Crypto Workshop](http://www.cryptoworkshop.com).
-
-Except where otherwise stated, this software is distributed under a license based on the MIT X Consortium license. To view the license, [see here](http://www.bouncycastle.org/licence.html). The OpenPGP library also includes a modified BZIP2 library which is licensed under the [Apache Software License, Version 2.0](http://www.apache.org/licenses/). 
-
-**Note**: this source tree is not the FIPS version of the APIs - if you are interested in our FIPS version please contact us directly at  [office@bouncycastle.org](mailto:office@bouncycastle.org).
-
-## Mailing Lists
-
-For those who are interested, there are 2 mailing lists for participation in this project. To subscribe use the links below and include the word subscribe in the message body. (To unsubscribe, replace **subscribe** with **unsubscribe** in the message body)
-
-*   [announce-crypto-csharp-request@bouncycastle.org](mailto:announce-crypto-csharp-request@bouncycastle.org)  
-    This mailing list is for new release announcements only, general subscribers cannot post to it.
-*   [dev-crypto-csharp-request@bouncycastle.org](mailto:dev-crypto-csharp-request@bouncycastle.org)  
-    This mailing list is for discussion of development of the package. This includes bugs, comments, requests for enhancements, questions about use or operation.
-
-**NOTE:**You need to be subscribed to send mail to the above mailing list.

-## Feedback 
-
-If you want to provide feedback directly to the members of **The Legion** then please use [feedback-crypto@bouncycastle.org](mailto:feedback-crypto@bouncycastle.org), if you want to help this project survive please consider [donating](https://www.bouncycastle.org/donate).
-
-For bug reporting/requests you can report issues here on github, via feedback-crypto if required, and we also have a [Jira issue tracker](http://www.bouncycastle.org/jira). We will accept pull requests based on this repository as well.
