Global Variables

Global Variables

FILE: the name of the output file. This is a Flow
variable and it returns a string.

FILEPATH: the path of the output file. This is a Flow
variable and it returns a string.

ERROR_MESSAGE: the error message generated by the
component when an error occurs. This is an After variable and it returns a string. This

Decrypting a GnuPG-encrypted file and display its content

The following scenario describes a three-component Job that decrypts a GnuPG-encrypted
file and displays the content of the decrypted file on the Run console.


Dragging and linking the components

  1. Drop a tGPGDecrypt component, a tFileInputDelimited component, and a tLogRow component from the Palette to the design workspace.
  2. Connect the tGPGDecrypt component to the
    tFileInputDelimited component using a
    Trigger > OnSubjobOk link, and connect the tFileInputDelimited component to the tLogRow component using a Row > Main link.

Configuring the components

  1. Double-click the tGPGDecrypt to open its
    Component view and set its


  2. In the Input encrypted file field, browse
    to the file to be decrypted.
  3. In the Output decrypted file field, enter
    the path to the decrypted file.


    If the file path contains accented characters, you will get an
    error message when running the Job.

  4. In the GPG binary path field, browse to
    the GPG command file.
  5. In the Passphrase field, enter the
    passphrase used when encrypting the input file.
  6. Double-click the tFileInputDelimited
    component to open its Component view and
    set its properties:


  7. In the File name/Stream field, define the
    path to the decrypted file, which is the output path you have defined in the
    tGPGDecrypt component.
  8. In the Header, Footer and Limit fields,
    define respectively the number of rows to be skipped in the beginning of the
    file, at the end of the file and the number of rows to be processed.
  9. Use a Built-In schema. This means that it
    is available for this Job only.
  10. Click Edit schema and edit the schema for
    the component. Click twice the [+] button
    to add two columns that you will call idState and
  11. Click OK to validate your changes and
    close the editor.


  12. Double-click the tLogRow component and
    set its properties:


  13. Use a Built-In schema for this scenario.
  14. In the Mode area, define the console
    display mode according to your preference. In this scenario, select
    Table (print values in cells of a

Saving and executing the Job

  1. Press Ctrl+S to save your Job
  2. Press F6 or click Run from the Run tab to run


The specified file is decrypted and the defined number of rows of the decrypted
file are printed on the Run console.
