Download Sn.exe ##BEST##

I want to experiment with signing my .Net assemblies with a strong name. So I downloaded and installed the windows SDK, and then did Dir /s sn.exe in order to find the one directory where it was installed.

OK .. I think I see what I did here. According to Hans' comment there should already have been a copy of sn.exe lying around on my computer. In hindsight I believe that I missed it when I scanned for it before installing the SDK.

To use a Microsoft Dynamics NAV Windows client control add-in on a Microsoft Dynamics NAV Windows client page, you must register the assembly that contains the control add-in on the Control Add-ins page of the Microsoft Dynamics NAV 2016 database. To register an assembly, you provide the assembly's public key token. The public key token is a unique 16-character key that is given to the assembly when it is built and signed in Microsoft Visual Studio. To determine the public token key, you can run the Strong Name tool (sn.exe) on the assembly. The sn.exe is available with the Microsoft .NET Framework SDK. For more information about how to sign assemblies, see Strong Name Signing (sn.exe) or How to: Create a Windows Client Control Add-in.

In case you reset your key container to a new one, and forget where it is.. you can reset the key container for the strong name utility using sn.exe -c. So, if the account access fix doesn't work, you may be using an alternate key store so a reset may be in order.

You tell whether an Assembly/DLL has been successfully strong-named using the Strong Name Tool (sn.exe) (which can be found somewhere like here: C:\Program Files\Microsoft SDKs\Windows\v7.0A\bin\sn.exe) by running the following at the command line:

Note that the Public key in the output from sn.exe matches the highlighted public key in the image immediately above it (of course you should ignore the spaces between pairs of digits in the screen shot).

Of course, you can use sn.exe and signtool.exe together (one after another) to examine an assembly to ascertain both whether it is strongly named and whether it has been digitally signed.

System.Security.Cryptography provides functions to work with RSA keypairs. These functions are wrappers on the Win32 Crypto API. However, the methods provided in the 1.1 Framework do not easily parse SNK keyfiles created by sn.exe. The reason is that none of the methods will accept a PRIVATEKEYBLOB or PUBLICKEYBLOB structure directly. Therefore, it is necessary to write some extra code to parse those structures. Furthermore, there are additional (some would say obscure) tweaks on CpParameters required to get an SNK keyfile to import correctly.

You can make a new assembly keypair by running sn.exe which is available from the Framework SDK. To make a new keypair run "sn.exe -k keypair.snk". To export just the public key from your keypair, use "sn.exe -p keypair.snk pubkey.pub".

The guts of the app lie in RSA1024Util.cs. I hardcoded the class to use 1024 bit encryption because currently sn.exe only generates 1024 bit keyfiles. (As an aside, I wonder why 2048 bits aren't supported for assembly keys? Cryptographers have lately been warning about the eventual fall of 1024 bit keys..)

There is one other not-well-documented switch that needs to be thrown in order to get the SNK file to be imported correctly. Keys generated by sn.exe have the KeyNumber set to 2, which is "AT_SIGNATURE". For more information see

To get started you need to download sn.exe and all referenced management packs. For OpsMgr 2007, these can be found in the Program Files\Operations Manager folder. For OpsMgr 2012, these can be found on the installation media. I have uploaded sn.exe and the management packs you need. Download them from here.

sn.exe, also known as a Microsoft .NET Strong Name Utility file, was created by Microsoft for the development of Microsoft .NET Framework. EXE files fall under under the Win64 EXE (Executable application) file type category.

The first version of sn.exe was released for the Windows 10 Operating System on 04/12/2010 inside Microsoft Visual Studio 2010 Ultimate 2010. This file version is latest update offered from Microsoft, according to our records.

In this short article, you will discover detailed file information, steps for troubleshooting EXE file problems with sn.exe, and list of free downloads for every version that exists in our comprehensive file directory.

Runtime errors are Microsoft Visual Studio 2010 Ultimate errors that occur during "runtime". Runtime is pretty self-explanatory; it means that these EXE errors are triggered when sn.exe is attempted to be loaded either when Microsoft Visual Studio 2010 Ultimate is starting up, or in some cases already running. Runtime errors are the most common form of EXE error you will encounter using Microsoft Visual Studio 2010 Ultimate.

In most cases, sn.exe runtime errors occurring while the program is running will result in the program terminating abnormally. Most of these sn.exe error messages mean that Microsoft Visual Studio 2010 Ultimate was either unable to locate this file on startup, or the file is corrupt, resulting in a prematurely-aborted startup process. Generally, Microsoft Visual Studio 2010 Ultimate will be unable to start without resolving these errors.

Finding the source of the sn.exe error is key to properly resolving these errors. Although most of these EXE errors affecting sn.exe will happen during startup, occasionally you will encounter a runtime error while using Microsoft .NET Framework. This can occur due to poor programming on behalf of Microsoft Corporation, conflicts with other software or 3rd-party plug-ins, or caused by damaged and outdated hardware. Also, these types of sn.exe errors can occur if it has been accidentally moved, deleted, or corrupted by a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.

When the first two steps haven't solved your issue, it might be a good idea to run Windows Update. Many sn.exe error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

If none of the previous three troubleshooting steps have resolved your issue, you can try a more aggressive approach (Note: Not recommended for amateur PC users) by downloading and replacing your appropriate sn.exe file version. We maintain a comprehensive database of 100% malware-free sn.exe files for every applicable version of Microsoft Visual Studio 2010 Ultimate. Please follow the steps below to download and properly replace you file:

GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve sn.exe problems. To avoid data loss, you must be sure that you have backed-up all of your important documents, pictures, software installers, and other personal data before beginning the process. If you are not currently backing up your data, you need to do so immediately.

CAUTION : We strongly advise against downloading and copying sn.exe to your appropriate Windows system directory. Microsoft typically does not release Microsoft Visual Studio 2010 Ultimate EXE files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing sn.exe and all other EXE files for Microsoft Visual Studio 2010 Ultimate. An incorrectly installed EXE file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.

1) I give the assembly a strong name.

(By specifying a key-file in the AssemblyInfo.cs-File)/using sn.exe.2) I compile the assembly without strong name.

Afterwards I attach a signature to the binary using signcode.exe

(like it is done for COM)Thank youFlorian Zug

I was stunned and looked all around to try and figure this out. After all, I can create an asymmetric key from a file. You use some other program to create the key files, like sn.exe from the Visual Studio resource kit, but you apparently can't get this key back out of SQL Server once it's in there.

To sign the library we need to generate a strong name key. To do that we open the Visual Studio console and change main directory to main library project directory and use sn.exe tool provided with Microsoft.

After much panicked running in circles, screaming and shouting I found the sn.exe tool - this is used to validate/add strong names to assemblies. When running it against the Win.Misc DLL, it did in fact have a bad "strong name". I then checked another copy of the same DLL in a different location, and it came back as being ok. The byte count between the two files was identical, but the MD5 hashes were different.

First of all, you need the .NET Framework SDK (any version) because we will be using 3 tools that are part of it, namely : sn.exe, tlbimp.exe and gacutil.exe. The .NET Framework SDK (any version) is a free download on the Microsoft website.

This external assembly reference is missing the all-important public key token reference. Before we can add it, we need to know what the public key token is for Bar.dll. To determine this, we can use the sn.exe utility, like so:

To accomplish this task we will use the sn.exe utility. As we saw before we can use sn.exe -Tp to view the public key token, so what we are going to do now to drop the assembly verification is running sn.exe the following way (as administrator).

You can use full path of sn.exe or set the path of sn.exe in your Path of System Environment Variable Path in Window settings.

In my computer it is installed by Visual Studio in: C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.7.2 Tools\x64.

In this example, the PFX file name is key.pfx.

We use a simple windows container with just sn.exe and an azure agent on a servercore:ltsc2022 image. We have some custom scripts that run install some MSIs and copy some test data, and use VSTest to run, all hooked up through a release pipeline. You might be asking why a release pipeline - currently we do this because we want to execute our release code via the installer for our testing. ff782bc1db
