Our scenario is like this, we have to do digital sign on transaction part of the payload and signed data need to insert in header part of the payload that is signature tag.

What is the target adapter you are using? It could be supported off the shelf by the target adapter type.

Hello Murali,

From your data i can infer that you are sending pain 001 file. Is it to the Bank directly or through SWIFT?

And how did you add the signature field to your datatype? Is it a part of the pain 001 structure datatype?

Nitin

Hello Murali,

What is the UDF signData doing? And why you are not using the signing methods mentioned in previous replies?

Dear Nitin,

Signdata udf function will check the sign in canonical form which is another udf as per bank .

udf bellow

AbstractTrace trace = container.getTrace();

  Sign_Data sp = new Sign_Data();

  signedData = sp.Sign_data(data, KeyStoreview, KeyStoreCert, trace);

  return signedData;
