If this Step 2 fails as well, please proceed to the Step 3 below. The contents of infile must be a public key previously generated from a key pair file using -p.
Do not use the -t[p] option to extract the token directly from a key pair file. To save space, the common language runtime stores public key tokens in the manifest as part of a reference to another assembly when it records a dependency to an assembly that has a strong name. The -tp option displays the public key in addition to the token.
If the AssemblySignatureKeyAttribute attribute has been applied to the assembly, the token is for the identity key, and the name of the hash algorithm and the identity key is displayed. Note that this option does not verify the assembly signature and should not be used to make trust decisions. This option only displays the raw public key token data.
Displays the public key token for assembly. The assembly must be the name of a file that contains an assembly manifest. To save space, the runtime stores public key tokens in the manifest as part of a reference to another assembly when it records a dependency to an assembly that has a strong name.
The -Tp option displays the public key in addition to the token. Test-signs the signed or partially signed assembly with the key pair in infile. Test-signs the signed or partially signed assembly with the key pair in the key container container.
Verifies the strong name in assembly , where assembly is the name of a file that contains an assembly manifest. Verifies the strong name in assembly. Unlike the -v option, -vf forces verification even if it is disabled using the -Vr option.
Creates a registration entries. The rules for assembly naming that apply to the -Vr option apply to —Vk as well. For information about the userlist and infile options, see the —Vr option. Registers assembly for verification skipping. Optionally, you can specify a comma-separated list of user names the skip verification should apply to. If you specify infile , verification remains enabled, but the public key in infile is used in verification operations.
For strongname , specify the string of hexadecimal digits representing the tokenized form of the public key. See the -t and -T options to display the public key token. PKC use public key and private key concept. Following are the step to generate a strong name and sign an assembly:. This wills popup the command prompt for you. Step3: This will create the file at the following location. When you open the file that has been generated by the strong name tool.
This is not a readable format because of security reasons. We need to assign it to the project. Step5: This will assign the strong name to this project. Then compile the project again to reflect the changes.
To remove the assembly run this command. More about Strong Name: You assign an assembly a strong name by associating the assembly with a pair of 1,bit cryptographic public and private keys. The actual process varies slightly, depending on whether the developer has access to the private key. In larger, security-oriented corporations, most developers do not have access to the private key.
Instead, only a few members of a final QA or security team can access the private key. In order to assign one or more assemblies a strong name, you must first create the 1,bit public and private key pair. EXE , like so:. The resulting key file contains both the public and the private key. You can extract the public key from the file and place it in a separate file like this:.
Typically, you will only perform the above steps once per corporation or division because all assemblies you produce can use the same public and private keys as long as the assemblies have unique friendly text names. Next, you need to associate the 1,bit public key with an assembly. In effect, this makes the public key an extension of the friendly text name of the assembly.
Alternatively, when you only have access to the key file that contains just the public key, you must enable delay signing of the assembly. Sign up using Email and Password. Post as a guest Name.
