Generate unsigned manifests

Signing the ClickOnce manifests is optional for .exe-based applications. The following procedures show how to generate unsigned ClickOnce manifests.

How

Important

Unsigned manifests can simplify development and testing of your application. However, unsigned manifests introduce substantial security risks in a production environment. Only consider using unsigned manifests if your ClickOnce application runs on computers within an intranet that is completely isolated from the internet or other sources of malicious code.

By default, ClickOnce automatically generates signed manifests unless one or more files are specifically excluded from the generated hash. In other words, publishing the application results in signed manifests if all files are included in the hash, even when the Sign the ClickOnce manifests check box is cleared.

To generate unsigned manifests and include all files in the generated hash

  1. To generate unsigned manifests that include all files in the hash, you must first publish the application together with signed manifests. Therefore, first sign the ClickOnce manifests by following one of the previous procedures, and then publish the application.

  2. On the Signing page, clear the Sign the ClickOnce manifests check box.

  3. Reset the publish version so that only one version of your application is available. By default, Visual Studio automatically increments the revision number of the publish version every time that you publish an application. For more information, see How to: Set the ClickOnce publish version.

  4. Publish the application.

To generate unsigned manifests and exclude one or more files from the generated hash

  1. On the Signing page, clear the Sign the ClickOnce manifests check box.

  2. Open the Application Files dialog box and set the Hash to Exclude for the files that you want to exclude from the generated hash.

    Note Aptana studio download for mac.

    Excluding a file from the hash configures ClickOnce to disable automatic signing of the manifests, so you do not need to first publish with signed manifests as shown in the previous procedure.

  3. Publish the application.

Since this lesson assumes that you don't yet have such keys, you are going to create a keystore named examplestore and create an entry with a newly generated public/private key pair (with the public key in a certificate).

Type the following command in your command window to create a keystore named examplestore and to generate keys:

You will be prompted to enter passwords for the key and keystore.

Subparts of the keytool Command

How Are Signing Keys Generated Money

Let's look at what each of the keytool subparts mean.

  • The command for generating keys is -genkey.
  • The -alias signFiles subpart indicates the alias to be used in the future to refer to the keystore entry containing the keys that will be generated.
  • The -keystore examplestore subpart indicates the name (and optionally path) of the keystore you are creating or already using.
  • The storepass value that you are promted for specifies the keystore password.
  • The keypass value that you are prompted for specifies a password for the private key about to be generated. You will always need this password in order to access the keystore entry containing that key. The entry doesn't have to have its own password. When you are prompted for the key password, you are given the option of letting it be the same as the keystore password.

Note: For security reasons you should not set your key or keystore passwords on the command line, because they can be intercepted more easily that way.

Distinguished-Name Information

If you use the preceding keystore command, you will be prompted for your distinguished-name information. Following are the prompts; the bold indicates what you should type.

Command Results

The keytool command creates the keystore named examplestore (if it doesn't already exist) in the same directory in which the command is executed. The command generates a public/private key pair for the entity whose distinguished name has a common name of Susan Jones and the organizational unit of Purchasing.

The command creates a self-signed certificate that includes the public key and the distinguished-name information. (The distinguished name you supply will be used as the 'subject' field in the certificate.) This certificate will be valid for 90 days, the default validity period if you don't specify a -validity option. Halo 2 pc cd key generator. The certificate is associated with the private key in a keystore entry referred to by the alias signFiles.

Self-signed certificates are useful for developing and testing an application. However, users are warned that the application is signed with an untrusted certificate and asked if they want to run the application. To provide users with more confidence to run your application, use a certificate issued by a recognized certificate authority.

Note: The command could be shorter if option defaults are accepted or you wish to be prompted for various values. Whenever you execute a keytool command, defaults are used for unspecified options that have default values, and you are prompted for any required values. For the genkey command, options with default values include alias (whose default is mykey), validity (90 days), and keystore (the file named .keystore in your home directory). Required values include dname, storepass, and keypass.
