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 properties:

  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.

    Warning

    If the file path contains accented characters, you will get an error message when running the Job. For more information on what to do when the accents are not supported, see the Talend Installation Guide.

  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 labelState.

  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.
