Encrypt txt and xls file on AL11 without PI. I have to use GPG as our OS is LINUX.

[virendra_kedia1]

Hello Experts!

I have read many posts on GPG encryption and I am not able to find the exact solution, hence raising a new thread.

Requirement: We have multiple files on AL11 directory we need to encrypt them and move the encrypted files to different folder (later to be consumed by third party).

What I have tried so far: I tried creating SM69 events with OS command as 'gpg', parameters of OS command '-e', additional parameters '-r <userid> <AL11 path of file>' - It is giving me error no public key.

Question 1: Where should I pass public key, with which command?

We have received public key which is around 1600 long characters and the FM 'SXPG_EXECUTE_COMMAND' additional parameters is only 255 characters.

Question 2: How to accommodate this along with file path?

Even I tried below code:

CALL 'SYSTEM' ID 'COMMAND' FIELD lv_cmd ID 'TAB' lt_tab[].

Where lv_cmd contains public key too alongwith AL11 path, But I am getting sy-subrc = 1, and lt_tab[] is empty.

FYI: GPG is installed @OS level.

Request you to guide me on correct path. I think I am very close to solution but very far too 😞

Any hint/help would be appreciated.

Why do you have to do this in SAP? It seems like an independent process that could be done at the OS level, outside of SAP ERP.

As an alternative, instead of calling GPG (exe?) you could create a BAT file, assuming the key is not something dynamically generated from SAP.

Hi,

Just suggesting , download your file to location and encrypt it using bat file. This BAT file can call using SAP. You have to call BAT file in same download program.Execute bat file using below BAPI. In the bat file execute your exe file or encrypt software.

 CALL METHOD CL_GUI_FRONTEND_SERVICES=>EXECUTE
    EXPORTING
*     DOCUMENT               = "'C:\test\encrypt.bat'
      APPLICATION            = 'C:\test\encrypt.bat'
      PARAMETER              = ''
      DEFAULT_DIRECTORY      = ''
      MAXIMIZED              = ' '
      MINIMIZED              = 'X' "If you need the DOS window to be minimized
    EXCEPTIONS
      CNTL_ERROR             = 1
      ERROR_NO_GUI           = 2
      BAD_PARAMETER          = 3
      FILE_NOT_FOUND         = 4
      PATH_NOT_FOUND         = 5
      FILE_EXTENSION_UNKNOWN = 6
      ERROR_EXECUTE_FAILED   = 7
      OTHERS                 = 8.

Undoubtedly, you should try GPG via Linux command line, and when OK, you will try to use SXPG_EXECUTE_COMMAND. Did you import the public key? It's nicely explained here for example: https://yanhan.github.io/posts/2017-09-27-how-to-use-gpg-to-encrypt-stuff.html?source=post_page-----...

Hello Sunil,

For this case we are uploading normal files in AL11 and then basis is encrypting it using some batch files with OS commands.
