How to find the public key token for a .NET DLL or assembly

Public Key Tokens with sn

Just run sn -T followed by your DLL or assembly. Here’s an example:

PS > sn -T "C:\dev\System.Data.SQLite.dll"

Microsoft (R) .NET Framework Strong Name Utility  Version 3.5.30729.1
Copyright (c) Microsoft Corporation.  All rights reserved.

Public key token is db937bc2d44ff139

Public Key Tokens with gacutil

If the DLL is in the GAC, you can do the same thing with gacutil:

PS > gacutil -l System.Data.SQLite
Microsoft (R) .NET Global Assembly Cache Utility. Version 4.0.30319.1
Copyright (c) Microsoft Corporation. All rights reserved.

The Global Assembly Cache contains the following assemblies:
System.Data.SQLite, Version=1.0.84.0, Culture=neutral, 
PublicKeyToken=db937bc2d44ff139, processorArchitecture=AMD64
