Jan 20, 2010  Generate a Key Pair. Before you do anything with GPG, you will need to generate a key pair for yourself. Once you have you own key pair, you can use your private key to sign artifacts, and distribute your public key to public key servers and end-users so that they can validate artifacts signed with your private key. Generate a key pair like this. Each key is a JSON Web Token with a defined length per the algorithm used for encryption and signing. In the event that keys are not generated by the deployer, CAS will attempt to auto-generate keys and will output the result for each respected key.

If you want to publish an application by using ClickOnce deployment, the application and deployment manifests must be signed with a public/private key pair and signed using Authenticode technology. You can sign the manifests by using a certificate from the Windows certificate store or a key file.

For more information about ClickOnce deployment, see ClickOnce security and deployment.

Signing the ClickOnce manifests is optional for .exe-based applications. For more information, see the 'Generate unsigned manifests' section of this document.

For information about creating key files, see How to: Create a public-private key pair.

Note

Visual Studio supports only Personal Information Exchange (PFX) key files that have the .pfx extension. However, you can select other types of certificates from the current user's Windows certificate store by clicking Select from Store on the Signing page of project properties.

Sign using a certificate

  1. Go to the project properties window (right-click the project node in Solution Explorer and select Properties). On the Signing tab, select the Sign the ClickOnce manifests check box.

  2. Click the Select from Store button.

    The Select a Certificate dialog box appears and displays the contents of the Windows certificate store.

    Tip

    If you click Click here to view certificate properties, the Certificate Details dialog box appears. This dialog box includes detailed information about the certificate and additional options. Click Certificates to view additional help information.

  3. Select the certificate that you want to use to sign the manifests.

    Many downloads like Smartmovie Player 4.15 may also include a crack, serial number, unlock code, cd key or keygen (key generator). If this is the case it is usually found in the full download archive itself. License

  4. Additionally, you can specify the address of a timestamp server in the Timestamp server URL text box. This is a server that provides a timestamp specifying when the manifest was signed.

Sign using an existing key file

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

  2. Click the Select from File button.

    The Select File dialog box appears.

  3. In the Select File dialog box, browse to the location of the key file (.pfx) that you want to use, and then click Open.

    Note

    This option supports only files that have the .pfx extension. If you have a key file or certificate in another format, store it in the Windows certificate store and select the certificate is described in the previous procedure. The selected certificate's purpose should include code signing.

    The Enter password to open file dialog box appears. (If the .pfx file is already stored in your Windows certificate store or is not password protected, you aren't prompted to enter a password.)

  4. Enter the password to access the key file, and then select Enter.

Note

The .pfx file cannot include certificate chaining information. If it does, the following import error will occur: Cannot find the certificate and private key for decryption. To remove the certificate chaining information, you can use Certmgr.msc and disable the option to Include all certificates when exporting the *.pfx file.

Sign using a test certificate

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

  2. To create a new certificate for testing, click the Create Test Certificate button.

  3. In the Create Test Certificate dialog box, enter a password to help secure your test certificate.

Generate unsigned manifests

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

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.

    Public key modulus and exponent Hi, I need to find the public keys modulus and exponent. I have loaded a private/public key generated by the openssl executable with the function PEMreadbioRSAPrivateKey and using the function PEMwriteRSAPUBKEY can print the private key. Reconstruct RSA public key from exponent and modulus Via ASN1 definition and OpenSSL. Create an asn1 definition file, replace the yellow color value with the value obtained in step (1). Openssl asn1parse -genconf def.asn1 -out pubkey.der -noout (5) Use OpenSSL to convert DER to PEM format. Openssl generate public key from modulus and exponent. The modulus and public exponent are in the last BIT STRING, offset 19, so use -strparse: This will give you the modulus and the public exponent, in hexadecimal (the two INTEGERs): That's probably fine if it's always the same key, but this is probably not very convenient to put in a script.

  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

    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.

In Preparing an App for Releasethe Archive Manager was used to build the app and place it in an archive forsigning and publishing. This section explains how to create an Androidsigning identity, create a new signing certificate for Androidapplications, and publish the archived app ad hoc to disk. Theresulting APK can be sideloaded into Android devices without goingthrough an app store.

In Archive for Publishing,the Distribution Channel dialog presented two choices fordistribution. Select Ad-Hoc:

In Archive for Publishing,the Sign and Distribute.. dialog presented us with two choices fordistribution. Select Ad-Hoc and click Next:

Create a New Certificate

After Ad-Hoc is selected, Visual Studio opens the SigningIdentity page of the dialog as shown in the next screenshot. Topublish the .APK, it must first be signed with a signing key (alsoreferred to as a certificate).

An existing certificate can be used by clicking the Import button and then proceeding toSign the APK. Otherwise, click the click the+ button to create a new certificate:

The Create Android Key Store dialog is displayed; use this dialogto create a new signing certificate that can use for signingAndroid applications. Enter the required information (outlined in red)as shown in this dialog:

The following example illustrates the kind of information that must be provided. Click Create to create the new certificate:

The resulting keystore resides in the following location:

C:UsersUSERNAMEAppDataLocalXamarinMono for AndroidKeystoreALIASALIAS.keystore

For example, using chimp as the alias, the above steps would create a new signingkey in the following location:

C:UsersUSERNAMEAppDataLocalXamarinMono for AndroidKeystorechimpchimp.keystore

Note

Be sure to back up the resulting keystore file and password in asafe place – it is not included in the Solution. If you lose yourkeystore file (for example, because you moved to another computer orreinstalled Windows), you will be unable tosign your app with the same certificate as previous versions.

For more information about the keystore, seeFinding your Keystore's MD5 or SHA1 Signature.

After clicking Ad-Hoc, Visual Studio for Mac opens the Android SigningIdentity dialog as shown in the next screenshot. To publish the .APK,it must first be signed it with a signing key (also referred to as acertificate). If a certificate already exists, click the Import anExisting Key button to import it and then proceed toSign the APK Otherwise, click the Create a NewKey button to create a new certificate:

The Create New Certificate dialog is used to create a new signingcertificate that can be used for signing Android applications. ClickOK after entering in the necessary information:

The resulting keystore resides in the following location:

~/Library/Developer/Xamarin/Keystore/alias/alias.keystore

For example, the above steps might create a new signingkey in the following location:

~/Library/Developer/Xamarin/Keystore/chimp/chimp.keystore

Sign the APK

When Create is clicked, a new key store (containing a newcertificate) will be saved and listed under Signing Identity as shownin the next screenshot. To publish an app on Google Play, clickCancel and go toPublishing to Google Play.To publish ad-hoc, select the signing identity to use for signing andclick Save As to publish the app for independent distribution. Forexample, the chimp signing identity (created earlier) is selectedin this screenshot:

Next, the Archive Manager displays the publishing progress. Whenthe publishing process completes, the Save As dialog opens to askfor a location where the generated .APK file is to bestored:

Navigate to the desired location and click Save. If the keypassword is unknown, the Signing Password dialog will appear toprompt for the password for the selected certificate:

After the signing process completes, click Open Distribution:

As seen here, a new certificate was added to the key store. To publishan app on Google Play, click Cancel and go toPublishing to Google Play.Otherwise click Next to publish the app ad-hoc (for independentdistribution) as shown in this example:

The Publish as Ad Hoc dialog provides a summary of the signed appbefore it is published. If this information is correct, clickPublish.

The Output APK file dialog will save the APK to the path specified. Click Save.

Next, enter the password for the certificate (the password that wasused in the Create New Certificate dialog) and click OK:

The APK is signed with the certificate and saved to the specifiedlocation. Click Reveal in Finder:

This opens the finder to the location of the signed APK file:

The APK is ready to copy from the finder and send to its finaldestination. It's a good idea to install the APK on an Android deviceand try it out before distribution. SeePublishing Independentlyfor more information about publishing an ad-hoc APK.
