How to get OPDA Cer & Key file-How to sign applications-Tutorial-Step by Step-100% working

What is Code Signing / Application Signing?

Application Signing is the digital process of confirmation of the software author and guarantee that the code has not been altered or corrupted since it was signed by use of a cryptographic hash. Code signing helps us in many features. The most common use of code signing is to provide security when deploying.

Why we need signing?

In most symbian phones whenever you try to install new software/application. It shows an error message i.e.

Certificate error. Contact to the application supplier. 

This message caused lot of frustration.  Because it is too difficult to find a application first for download. Then save it to memory card, after all of this time taking procedure when you find this type of message you caused lot of tension. This problem will be solved by signing your application.

How can you sign a file?

This tutorial helps you to find the way to sign your unsigned Files/Applications. There are three ways to sign a application
  • Online Signing means that you upload a unsigned Application on any online website who offers online signing (OPDA). And get a signed application after online signing. This is time taking process.
  • Computer Signing needs PC software for signing and two other files Cer file and Key file on your computer to complete your mobile application signing. This is famous method to sign your unsigned applications.
  • Mobile Signing required Mobile signing application and the two files Cer file and Key file. Easy way to sign your mobile applications from your mobile phones. 

How to get OPDA Certificate and Key files with the New System?

There are many online websites who offers you to get certificate and key file. But OPDA is one and only website which I recommend you to download certificate and key file.
Step 1: Visit the site of OPDA
Click on "Register" on the top right corner to register yourself
Step 2: A registration form will be open. Fill this form.
After all of this a message box will shown on the screen. "Registered Successfully"
Step 3: After Register Successfully a Login page will open. The thing you have to do is to enter your login information in the required fields. As shown below.
Step 4: This "Certificate" page shows your certificate information. You have no certificate yet. To get certificate click on the highlighted button "Apply Certificate"
 Step 5: Fill the form carefully as shown through image below.
After apply certificate successfully you a new window will be shown on the screen. Which shows information about your applied certificate information. If no window opens then click on this link to check your certificates. The thing important in this page to check the state of your certificate. If it shows "Normal". Its mean every thing is ok. If it is not "Normal" then there is some problem in your "Apply Certificate Form"
Note: If you click on the cer or key as highlighted with a red box in the image below then a new window will be open, asking for Donation. To avoid this Donation i found a hack and i explained this hack below in Step 6.
Step 6: Click on the top right corner on Chinese word to change the language of the page into the "Chinese".
Step 7: Now click the button as shown in the below image with highlighted circle, to "Login"
A new "Login" window will be open. Fill the form and enter the button highlighted in the box below in the image to login yourself.
A New window again shows your Applied Certificate information. Please note the Highlighted box in the image below. Here you found "cer" and "key". Click on them to download your certificate and key file with out any donations.
 Select the required path to save your files.
Note: Your certificate is just for your device, which is valid for about four years from the moment of creation.
Now you can use these files to Sign your Unsigned Applications on your PC or on your mobile phone..

Friends don't fall in his trap. He himself is a culprit of cyber crimes. Certificate will never get produced....he just want to know your mobiles IMEI number issued by Nokia, Samsung etc....and use it in criminal activities such as bank frauds, credit card fraud, selling the original IMEI numbers to cheap & fraud chinese mobile companies. Kick that bastard's ass wherever you find him & handle him to police immediately !!!
