Visual studio sn tool

Note: This option does not verify that the input is only a public key. If the infile contains a key pair with a private key, the private key is also extracted.

Extracts the public key from the key pair in infile and stores it in outfile , optionally using the RSA algorithm specified by hashalg. When an assembly is delay-signed, only the public key is set at compile time and space is reserved in the file for the signature to be added later, when the private key is known. Extracts the public key from the key pair in container and stores it in outfile. If you use the hashalg option, the RSA algorithm is used to extract the public key.

Specifies whether the strong-name bypass policy is enforced. If you specify y , strong names for full-trust assemblies are not validated when loaded into a full-trust AppDomain. If you specify n , strong names are validated for correctness, but not for a specific strong name. The StrongNameIdentityPermission has no effect on full-trust assemblies. You must perform your own check for a strong name match.

The default is y. Note: On bit computers, you must set this parameter in both the bit and the bit instances of Sn. Re-signs a previously signed or delay-signed assembly with the key pair in infile.

If -Ra is used, hashes are recomputed for all files in the assembly. Re-signs a previously signed or delay-signed assembly with the key pair in container. If -Rca is used, hashes are recomputed for all files in the assembly.

Displays the token for the public key stored in infile. 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.

You do not want to negatively affect performance of apps using your assembly, so you want the assembly to be domain neutral. This requires strong-naming because a domain-neutral assembly must be installed in the global assembly cache. You want to centralize servicing for your app by applying publisher policy, which means the assembly must be installed in the global assembly cache. NET Core and. The runtime never validates the strong-name signature, nor does it use the strong-name for assembly binding.

If you are an open-source developer and you want the identity benefits of a strong-named assembly for better compatibility with. NET Framework, consider checking in the private key associated with an assembly to your source control system.
