Resolve UCI or move to direct APIs to send SMS

[aakashyadav-kgp]

Description: We use CDAC in himachal pradesh to send SMS. But recently we have not been able to send SMS via UCI. We have verified that the UCI-ODK-adapter is working properly. Chakshu said the CDAC API is not working that's why the issue. I tried to use the CDAC API directly via postman but got error 416.

API collection: Link

Now we want to update the key and test again using the Postman API to see if we need to fix something on UCI or CDAC integration end.

CDAC integration doc: https://mgov.gov.in/SMSServices

Acceptance criteria:

1. We want to receive 9/10 SMS to 4-5 different numbers. This can be tested by adding students in a school and triggering SMS via e-Samwad app to their parents.

key has to be generated from the function provided in https://mgov.gov.in/SMSServices and the value in key was actually secureKey.

Following is the hashGenerator function used.

public class App {

  public static String hashGenerator(
    String userName,
    String senderId,
    String content,
    String secureKey
  ) {
    // TODO Auto-generated method stub
    StringBuffer finalString = new StringBuffer();
    finalString
      .append(userName.trim())
      .append(senderId.trim())
      .append(content.trim())
      .append(secureKey.trim());
    // logger.info("Parameters for SHA-512 : "+finalString);
    String hashGen = finalString.toString();
    StringBuffer sb = null;
    MessageDigest md;
    try {
      md = MessageDigest.getInstance("SHA-512");
      md.update(hashGen.getBytes());
      byte byteData[] = md.digest();
      //convert the byte to hex format method 1
      sb = new StringBuffer();
      for (int i = 0; i < byteData.length; i++) {
        sb.append(
          Integer.toString((byteData[i] & 0xff) + 0x100, 16).substring(1)
        );
      }
    } catch (NoSuchAlgorithmException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
    }
    return sb.toString();
  }

  public static void main(String[] args) {
    System.out.println("Hello World!");
    System.out.println(
      hashGenerator(
        "hpgovt-hpssa",
        "HPGOVT",
        "Test 2",
        "5e92f23b-0d09-46ef-a428-dcd7cae79169"
      )
    );
  }
}

@aakashyadav-kgp will check on whether to use UCI or directly send messages through CDAC.

Talk to @suresh about moving to CDAC services directly and the future implementations. Needs to be picked up soon. @aakashyadav-kgp to create ticket for the same.
