1. Visual Studio Command Prompt Generate Certificate With Private Key Example
-->

Aug 05, 2019 Open a command prompt, change the directory to your folder with the configuration file and generate the private key for the certificate: openssl genrsa -out testCA.key 2048. This will create a file named testCA.key that contains the private key. This will be used with the next command to generate your root certificate. NOTE: Having created a root certificate from which client certificates will be generated, it is advisable to export this certificate along with its private key and keep somewhere safe. To generate a Self-Signed Client Certificate: Open the Visual Studio Express desktop Tools CMD line as Administrator. At the command prompt run the following.

Developer Command Prompt for Visual Studio enables you to use .NET Framework tools more easily. It's a command prompt that automatically sets specific environment variables. After opening Developer Command Prompt, you can enter the commands for .NET Framework tools such as ildasm or clrver.

Prerequisites

Search for the command prompt on your machine

You may have multiple command prompts, depending on the version of Visual Studio and any additional SDKs and workloads you've installed. If the following steps don't work, you can try to manually locate the files on your machine or start the command prompt from inside Visual Studio.

Windows 10

  1. Jun 22, 2014  Launch The Visual Studio Developer’s command prompt as Administrator. Most easy command to generate a certificate is. Makecert c:testCert.cer Ans here is complete one. Makecert -sk TestKey -pe -ss TestStore -sr CurrentUser -$ individual -n CN=Anupama Prabhakar c:testCert.cer Second command have exportable private key.
  2. Launch Visual Studio command prompt to use makecert. The name of my certificate authority is “Dev Certification Authority”. Below is the command to create the certificate authority. It will ask to set a password, go ahead and set it.
  1. Select Start and scroll to the letter V.

  2. Expand the Visual Studio 2019 folder.

  3. Choose Developer Command Prompt for VS 2019 (or the command prompt you want to use).

    Alternatively, you can start typing the name of the command prompt in the search box on the taskbar, and choose the result you want as the result list starts to display the search matches.

Windows 8.1

  1. Go to the Start screen, by pressing the Windows logo key on your keyboard for example.

  2. On the Start screen, press Ctrl+Tab to open the Apps list, and then press V. This brings up a list that includes all installed Visual Studio command prompts.

  3. Choose Developer Command Prompt for VS 2019 (or the command prompt you want to use).

Jun 09, 2019 This article describes how to recover a private key after you use the Certificates Microsoft Management Console (MMC) snap-in to delete the original certificate in Internet Information Services (IIS). You delete the original certificate from the personal folder in the local computer's certificate store.

Windows 7

  1. Choose Start and then expand All Programs.

  2. Choose Visual Studio 2019 > Visual Studio Tools > Developer Command Prompt for VS 2019, or the command prompt you want to use.

If you have other SDKs installed, such as the Windows 10 SDK or previous versions, you may see additional command prompts. Check the documentation for the individual tools to determine which version of the command prompt you should use.

Manually locate the files on your machine

Usually, the shortcuts for the command prompts you have installed are placed at the Start Menu folder for Visual Studio, such as in %ProgramData%MicrosoftWindowsStart MenuProgramsVisual Studio 2019Visual Studio Tools. But if, for some reason, searching for the command prompt doesn't produce the expected results, you can try to manually locate the shortcut on your machine. Try searching for the name of the command prompt file, such as VsDevCmd.bat, or go to the Tools folder, such as %ProgramFiles(x86)%Microsoft Visual Studio2019CommunityCommon7Tools (path changes according to your Visual Studio version, edition, and installation location).

Start the command prompt from inside Visual Studio

For easier access, you can add Developer Command Prompt, or any other command prompt, to the Tools menu in Visual Studio. To make the tool available, add it to the external tools list. Here are the steps:

  1. Open Visual Studio.

  2. On the start window, choose Continue without code.

  3. On the menu bar, choose Tools > External Tools.

  4. On the External Tools dialog box, choose the Add button. A new entry appears.

  5. Enter a Title for your new menu item such as Command Prompt.

  6. In the Command field, specify the file you want to launch, such as %comspec% or C:WindowsSystem32cmd.exe.

  7. In the Arguments field, specify where to find the specific command prompt you want to use, such as /k 'C:Program Files (x86)Microsoft Visual Studio2019CommunityCommon7ToolsVsDevCmd.bat'. This command launches the Developer Command Prompt that's installed with Visual Studio 2019 Community. Change this value according to your Visual Studio version, edition, and installation location.

  8. In the Initial directory field, specify the directory in which the command prompt will start. Choose a value such as Project Directory by selecting the arrow next to the field.

  9. Choose the OK button.

    The new menu item is added, and you can access the command prompt from the Tools menu.

Note

Although .NET Core supports strong-named assemblies, and all assemblies in the .NET Core library are signed, the majority of third-party assemblies do not need strong names. For more information, see Strong Name Signing on GitHub.

There are a number of ways to sign an assembly with a strong name:

  • By using the Signing tab in a project's Properties dialog box in Visual Studio. This is the easiest and most convenient way to sign an assembly with a strong name.

  • By using the Assembly Linker (Al.exe) to link a .NET Framework code module (a .netmodule file) with a key file.

  • By using assembly attributes to insert the strong name information into your code. You can use either the AssemblyKeyFileAttribute or the AssemblyKeyNameAttribute attribute, depending on where the key file to be used is located.

  • By using compiler options.

You must have a cryptographic key pair to sign an assembly with a strong name. For more information about creating a key pair, see How to: Create a public-private key pair.

Create and sign an assembly with a strong name by using Visual Studio

  1. In Solution Explorer, open the shortcut menu for the project, and then choose Properties.

  2. Choose the Signing tab.

  3. Select the Sign the assembly box.

  4. In the Choose a strong name key file box, choose Browse, and then navigate to the key file. To create a new key file, choose New and enter its name in the Create Strong Name Key dialog box.

Note

In order to delay sign an assembly, choose a public key file.

Create and sign an assembly with a strong name by using the Assembly Linker

Visual Studio Command Prompt Generate Certificate With Private Key Example

At the Developer Command Prompt for Visual Studio, enter the following command:

al/out:<assemblyName> <moduleName>/keyfile:<keyfileName>

Where:

  • assemblyName is the name of the strongly signed assembly (a .dll or .exe file) that Assembly Linker will emit.

  • moduleName is the name of a .NET Framework code module (a .netmodule file) that includes one or more types. You can create a .netmodule file by compiling your code with the /target:module switch in C# or Visual Basic.

  • keyfileName is the name of the container or file that contains the key pair. Assembly Linker interprets a relative path in relation to the current directory.

The following example signs the assembly MyAssembly.dll with a strong name by using the key file sgKey.snk.

For more information about this tool, see Assembly Linker.

Sign an assembly with a strong name by using attributes

  1. Add the System.Reflection.AssemblyKeyFileAttribute or AssemblyKeyNameAttribute attribute to your source code file, and specify the name of the file or container that contains the key pair to use when signing the assembly with a strong name.

  2. Compile the source code file normally.

    Note

    The C# and Visual Basic compilers issue compiler warnings (CS1699 and BC41008, respectively) when they encounter the AssemblyKeyFileAttribute or AssemblyKeyNameAttribute attribute in source code. You can ignore the warnings.

The following example uses the AssemblyKeyFileAttribute attribute with a key file called keyfile.snk, which is located in the directory where the assembly is compiled.

You can also delay sign an assembly when compiling your source file. For more information, see Delay-sign an assembly.

Sign an assembly with a strong name by using the compiler

Compile your source code file or files with the /keyfile or /delaysign compiler option in C# and Visual Basic, or the /KEYFILE or /DELAYSIGN linker option in C++. After the option name, add a colon and the name of the key file. When using command-line compilers, you can copy the key file to the directory that contains your source code files.

For information on delay signing, see Delay-sign an assembly.

The following example uses the C# compiler and signs the assembly UtilityLibrary.dll with a strong name by using the key file sgKey.snk.
