1. Create a Keystore Rule in Pega:

   • Ensure you have created a Keystore rule in Pega where the PKCS12 certificate is stored, and the client inputs the password.

2. Add PDFBox Library:

   • Include the necessary PDFBox JAR files in your Pega application to handle PDF operations.

3. Write Java Code to Access Keystore:

   • Use the Java KeyStore API to load the keystore and retrieve the certificate and private key. Here’s an example code snippet:

   import java.io.FileInputStream;
   import java.security.KeyStore;
   import java.security.PrivateKey;
   import java.security.cert.Certificate;
   
   public class KeystoreUtil {
       public static void main(String[] args) {
           try {
               // Load the keystore
               FileInputStream is = new FileInputStream("path/to/keystore.p12");
               KeyStore keystore = KeyStore.getInstance("PKCS12");
               keystore.load(is, "keystorePassword".toCharArray());
   
               // Retrieve the private key
               PrivateKey privateKey = (PrivateKey) keystore.getKey("alias", "keyPassword".toCharArray());
   
               // Retrieve the certificate
               Certificate cert = keystore.getCertificate("alias");
   
               // Use the private key and certificate for signing
               // Your signing logic here
   
           } catch (Exception e) {
               e.printStackTrace();
           }
       }
   }
   

4. Retrieve Keystore Filepath and Password:

   • Ensure that the filepath and password are correctly retrieved from the Pega Keystore rule. You can use Pega's API to get these details.

5. Handle Exceptions:

   • Add appropriate exception handling to manage any errors that occur during the keystore loading and certificate retrieval process.

Example Usage in Pega Activity

1. Create a Custom Activity:

   • Create a new activity in Pega and add a Java step to call the KeystoreUtil class.

2. Set Parameters:

   • Pass the keystore filepath and password as parameters to the Java step.

3. Call the Java Code:

   • Use the KeystoreUtil class to load the keystore and retrieve the certificate and private key.
