How to encrypt single field in a file

[sahithi_moparthi]

Hi,

  I have a scenario where i have to encrypt a single field in the file ?Could you please suggest best approach to design this interface.

Data :

File is coming with Bank and credit card details like:

<Record>

    <Field1> Creditcard Number </Field1>

   <Field2> Bank Name</Field2>

   <Field3> Address </Field3>

</Record>

I have to encrypt creditcard number only.How is it possible?

AFAIK with PGP encryption we can encrypt whole payload.

Please provide your valuable inputs.

Hi Hareesh,

I have gone through the document and that is the exact scenario i'm looking.I have a query on the Jar libarraies mentioned in the document.

when i'm implementing the scenario,i could not find the Jar files mentioned in the document.

com.sap.aii.af.cpa.svc.api.jar: <bin>/services/com.sap.aii.af.cpa.svc/lib

com.sap.aii.af.lib.mod.jar: <bin>/ext/com.sap.aii.af.lib\lib

com.sap.aii.af.ms.ifc_api.jar: <bin>/interfaces/com.sap.aii.af.ms.ifc/lib

com.sap.aii.af.svc_api.jar: <bin>/services/com.sap.aii.af.svc/lib

sap.com~tc~logging~java~impl.jar: <bin>/system

I have found the jar files in NWDS -> Plugins,but the libraries seems different than above:

Also tried to download the Jar files online but could not find the right one.

Please suggest where to get the jar files mentioned above to start the interface.

Thanks a lot for your timely response!!!

Hi Sahithi,

Please use the below code and map as per that screenshot.

and before you start write the code, pls import an jar/zip file in import archives in same namespace.

and add that as mentioned below

also dont forget add imports in import instructions(sun.misc.BASE64Encoder)

Note: you can get jar file from link : Download sun.misc.BASE64Decoder.jar : sun&amp;nbsp;&amp;laquo;&amp;nbsp;s&amp;nbsp;&amp;laquo;&amp;...

Sahithi,

Have you added jar in Archive used tab ?

Yes,

Hi,

1.In your UDF Encrypt, change the argument Name to input instead of encoder

2. Remove calculate1, calculate2 functions if you are not using it

its wont make sence if we do encript and again decript data in PI itself, the reason receiver system people ask is to secure/protect the data and the same time reciever system people should be able to decript the data.
