encrypt data in ABAP

Former Member — Thu, 20 Apr 2006 08:10:14 GMT

Hallo,

ich will send data from HR via an email-attachment (.txt) to an external Company. The data are selected and send in a Abap-Report. Because there sensitive Data, i will encrypt them in Abap. The Receiver shell decrypt the attachment without Abap, only in Windows by a special Key, Pin etc.

Has anyone an Idea to solve this Problem?

Thanks for help.

Regards,

Dieter

Hi Dieter,

You can try CL_BSP_UTILITY=>ENCODE_STRING, it was mentioned in the BSP Advanced Programming book, but I don't have with me now and I don't remember the details:-(

As far as I remember it uses a commonly used encryption type, so probable you can find a windows based decrypter application.

Hallo,

sorry Sharath and Peter but we have 4.6C, and the Class/Function isn't in our System.

I think i have to describe my problem in more detail.

First i read in Abap some Data and put it in an internal table. Then i send it via "SO_DOCUMENT_SEND_API1" with

Receiver Typ "U" to an external Receiver as an Attachment. This Attachment shell be secuered by Cryptation or by Password.

The Receiver shell open this Attachment with Password

or any other Key.

Thanks for Help.

Regards,

Dieter

I had a similar problem and the below code worked for me.

you can try this.
