Verisign signing - Java ME
Inorder for a commercial application which requires access to some specific APIs like JSR 75,JSR 205, JSR 135 etc requires the application to be signed by a professional certificate from third party certificate providers like Verisign or Thawte. Before buying out any certificate from these third parties, you have to make sure that the target phone's of your device supports these certificate. You can check it in the settings session of the target Mobile device.
I also came across this requiremnt of signing the application. For this I had gone for verisgn certificate & here is the procedure on how to get a Verisign certificate & Test your application
Step 1: you should have the latest JDK installed in the system.
Create a keystore
You have to generate a public/private key pair, for this enter the following command, specifying a name for your keystore and an alias as well.
C:\jdk1.3\bin\keytool -genkey -keyalg rsa -keystore <keystore_filename> -alias <alias_name>
Keytool prompts you to enter a password for your keystore, your name, organization, and address. The public/private key pair generated by keytool is saved to your keystore and will be used to sign J2ME applications. This key is never sent to VeriSign and is required to sign code. So you should make a copy of the public/private key pair and store it in a safe deposit box or other secure location. If the key is lost or stolen, contact VeriSign immediately to have it revoked.
Create a CSR
You need to generate a Certificate Signing Request (CSR) for the enrollment process.
1. The following command requests Keytool to create a CSR for the key pair in the keystore:
C:\jdk1.3\bin\keytool -certreq -file certreq.csr -keystore <keystore_filename> -alias <alias_name>
2. Begin the enrollment process for a Code Signing ID from the products and services section of the VeriSign Web site. 3. Copy the contents of the CSR and paste them directly into the VeriSign enrollment form. Open the file in a text editor that does not add extra characters (Notepad or Vi are recommended).
This is the end of requesting the certificates from Verisign.
Now Comes the signing part:
After verisign has verified your request, they will send an email with the digital id attached. You have to import it to the keystore.
To import your Sun Java Signing Code Signing Digital ID into your keystore, enter the following code with the path correct name for your file (for example, "cert.cer") to your Code Signing Digital ID.
C:\jdk1.3\bin\keytool -import -trustcacerts -keystore <keystore_filename> -alias <alias_name> -file cert.cer
Now sign the application by the two command prompt
java -jar JadTool.jar [ -addcert -alias keyAlias [ -keystore keystore ] [ -storepass password ] -inputjad inputJadFile -outputjad outputJadFile ]
java -jar JadTool.jar [ -addjarsig [ -jarfile jarFile ] -alias keyAlias [ -keystore keystore ] -storepass password -keypass keyPassword -inputjad inputJadFile -outputjad outputJadFile ]
