+# Vereign C++ Client Library
+
+## Overview
+
+Vereign C++ Client Library allows for digitally signing emails and documents, data encryption,
+and key-based authentication.
+
+FIXME: Add more info about the software architecture.
+
+## Build
+
+The project uses git submodules for the gRPC protobuf definitions.
+
+So after cloning run `git submodule update --init`.
+
+The protobuf definitions and the generated C++ gRPC client/server are located in
+[https://code.vereign.com/code/vcl-proto](https://code.vereign.com/code/vcl-proto) project and 
+are added as submodule at `proto` subdir.
+
+### Windows
+
+You need Visual Studio 2019 or alternatively install just the build tools and c++ compiler - go to
+[https://visualstudio.microsoft.com/downloads/](https://visualstudio.microsoft.com/downloads/)
+then scroll and open `Tools for Visual Studio 2019` and download/install `Visual Studio Build Tools 2019`.
+The 2019 build tools include cmake, and currently it is 3.16.19112601-MSVC_2.
+They also include Ninja build tool.
+
+**NOTE: Currently only builds with Ninja are tested under Windows**
+
+#### Build the third party dependencies
+
+Go to the `vcl/cpp` directory.
+
+First configure the cmake build.
+Open `x64 Native Tools Command Prompt` it is preconfigured with all the needed tools including cmake
+and ninja.
+
+```shell
+> mkdir cmake-build-vendor-debug
+> cd cmake-build-vendor-debug
+> cmake -G Ninja -DCMAKE_BUILD_TYPE=Debug ../vendor
+```
+
+Next build the dependencies.
+Note that this will take a while, and that it could be slowed a lot by the windows defender.
+You can configure the windows defender to the project directory.
+
+```shell
+> ninja
+```
+
+#### Build the vereign library
+
+Go to the `vcl/cpp` directory.
+
+```
+> mkdir cmake-build-debug
+> cd cmake-build-debug
+> cmake -G Ninja -DCMAKE_BUILD_TYPE=Debug ..
+> ninja vereign -v
+```
+
+The `vereign.dll` will be created inside `cmake-build-debug\bin\Debug` directory.
+
+### C API Usage
+
+For C/C++ users, the library has a single header file located in `include\vereign` directory.
+
+The service is started with `vereign_service_start`. This will start a gRPC server in its own thread(s).
+The call returns immediately.
+
+After the service is started you can use your favorite language generated gRPC client to communicate
+with the service.
+
+Use the `vereign_service_selected_port` function to get the listen port of the gRPC server.
+
+When you are finished with the service, for example upon shutdown of the application, one must use
+the `vereign_service_shutdown` API. It will shutdown the service and free any acquired resources.
+Afterwards the returned `vereign_service` pointer from the start call is invalid and must not be used anymore.
+
+For more detailed info check the source code documentation in the header
+[include/vereign/vereign.h](cpp/include/vereign/vereign.h).
+You can also look at C++ usage example in the C API integration test
+[tests/integration/integration_test.cc](cpp/tests/integration/integration_test.cc).
+
+The gRPC APIs are located here [https://code.vereign.com/code/vcl-proto/-/tree/master/proto%2Fvereign%2Fclient_library](https://code.vereign.com/code/vcl-proto/-/tree/master/proto%2Fvereign%2Fclient_library).
+
+FIXME: Add sample integration - for example for C#.
+
+
+TODO: Add more documentation/reference; instructions to generate doxygen reference.

+# Vereign C++ Client Library Storage Spec {#vcl_storage_spec}
+
+## Overview
+
+The Vereign C++ Library Storage is used for securely store locally user's identity and profile
+certificates.
+
+The storage is a key/value storage where the values are encrypted with `master key` using
+`AES256-GCM` cypher.
+
+The current backend of the storage is sqlite3, where the database file is normally located at 
+`${HOME}/vereign/db`.
+
+The `master key` key is provided in different way depending on the operating system.
+
+## windows master key
+
+Under windows [CNG](https://docs.microsoft.com/en-us/windows/win32/seccng/about-cng) is used for 
+generating a persistent RSA key pair 2048 bits long. The name of the key in the windows storage by 
+default is `vereign_key`. This key is used to encrypt a randomly generated AES256 key, and the 
+encrypted key is saved in the storage under a special key `__master_key`.
+
+## linux master key
+
+Under linux the user must provide a password (pin code).
+This password along with randomly generated salt is used to derive a master key using
+`PKCS5_PBKDF2_HMAC` with `SHA256` where the salt is 16 bytes and the iterations are 2^18.
+The salt and the iterations are stored in the storage under special keys `__master_key_salt` and
+`master_key_iterations`. Note that these are stored in plain form without encryption.
+
+## locking and storage tag
+
+Every time the storage is going to be modified the whole storage must be locked, which with the 
+sqlite3 backend is achieved with so called exclusive transaction.
+This is needed in order to have consistency when more then a single application use the same storage.
+
+But locking is not enough to achieve consistency. If an application A already had opened the storage,
+and application B reset the identity (changing the master key), and after some time A writes to the
+storage it will overwrite values written by B leaving the storage in a state where different values
+are encrypted with different keys.
+
+In order to prevent this, when the master key is created for the first time a 16 byte long random
+tag is generated and stored encrypted with the master key into a special key `__tag`.
+Then whenever a value must be written after the storage is locked additionally the `__tag` is read
+and decrypted. If the tag retrieval or decryption fails, and error is triggered and the write is
+cancelled.
+
+## encrypted values encoding
+
+As already mentioned the values are encrypted with `AES256-GCM`.
+
+The encrypted values are encoded according to the BNF grammars described below.
+
+The primitives used are:
+* `uint8` - a single byte.
+* `uint64` - unsigned 64 bit integer in Little Endian.
+* `bytes` - a sequence of bytes.
+
+### encoding version 1
+
+```
+Bytes = Size Data
+  Size = uint64
+  Data = bytes
+
+EncryptedValue = Version IV Tag EncryptedData
+  Version = uint8
+  IV = bytes
+  Tag = bytes
+  EncryptedData = bytes
+```
