    CSC - Cloud Signature Consortium

    Build Status Dependency Status

    A CSC RSSP -Cloud Signature Consortium Remote Signature Service Provider-, written in Node.js using SoftHSMv2 as HSM. This application follows the CSC API V1.0.4.0 specification. It also includes an OAuth 2.0 server for your particular needs.

    Installing globally via npm:

    npm install -g csc-server


    1. Install Mongodb from

    2. Install OpenSC that is needed for interacting with the SoftHSMv2 dll module. We will use pkcs11-tool exe.

    3. Install SoftHSMv2 or just copy it from the project's release binaries to the resources folder.

    • Set environment variabile SOFTHSM2_CONF=%path_to_softhsm2\lib\softhsm2.conf%
    • In the file path\to\softhsm2.conf, set directories.tokendir=%path_to_softhsm2\tokens_folder%
    • Initialize a new softhsm2 token with %path_to_softhsm2\bin\softhsm2-util.exe%
    softhsm2-util --init-token --slot 0 --label "mytoken"
    1. Install OpenSSL or just copy it from the project's release binaries to the resources folder.
    • Generate a new certificate and private key for your https/SSL/TLS service and put them in the resources folder of the application (the one provided in config.json. See point 5):
    openssl req -x509 -newkey rsa:4096 -keyout keySSL.pem -out certSSL.pem -days 365

    In the release version you will find the following binaries:

    • OpenSSL 1.1.1.d x86 (used by the app)
    • SoftHSMv2 (used by the app)
    • PKCS11Admin - 0.5.0 (Optional GUI to help you see the token objects)
    1. Configure the service settings. See Configuration.

    After you successfully installed and configured all the prerequistes, you can proceed to Usage.


    Create your own user:

    csc-server --createUser --user="username" --pass="password" --pin="pin"

    If you plan to use OAuth 2.0, create your own client:

    csc-server --createClient --name=name --id=id --secret=secret --redirectUri=redirectUri

    Start CSC Server:

    csc-server -l

    Now you have a fully functional CSC server.

    Example Usage

       csc-server [options]
      --createUser    Create a user using the arguments below.
           --user           Username of the user.

           --pin            PIN associated with the generated private key.
      --createClient  Create an OAuth 2.0 client using the arguments below.
           --name          Name of the client application.
           --id            Client id.',
           --secret        Client_secret.
           --redirectUri   Redirect_uri.
      --listen, -l     Start the server
           --silent, -s     Suppress log messages from output.
      --version, -v    Print the version and exit.
      --help, -h       Print this list and exit.
       csc-server -l
       csc-server --createUser --user=username --pass=password --pin=pin
       csc-server --createClient --name=name --id=id --secret=secret --redirectUri=redirectUri
